U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Summary
International trade is a critical component of the U.S. economy, with U.S. merchandise imports
amounting to $2.4 trillion and exports to $1.6 trillion in 2014. The efficient flow of legally traded
goods in and out of the United States is thus a vital element of the country’s economic security.
U.S. Customs and Border Protection (CBP), within the Department of Homeland Security (DHS),
is the primary agency charged with monitoring, regulating, and facilitating the flow of goods
through U.S. ports of entry (POEs). CBP’s policies are designed to (1) ensure the smooth flow of
imported cargo through U.S. POEs; (2) enforce trade and customs laws designed to protect U.S.
consumers and business and to collect customs revenue; and (3) enforce import security laws
designed to prevent weapons of mass destruction, illegal drugs, and other contraband from
entering the United States—a complex and difficult mission. Congress has a direct role in
organizing, authorizing, and defining CBP’s international trade functions, as well as appropriating
funding for and conducting oversight of its programs. In the Senate, on May 14, 2015, S. 1269
was incorporated into H.R. 644 (renamed the Trade Facilitation and Trade Enforcement Act of
2015) and subsequently passed by a vote of 78-20. Bills introduced in the House include H.R.
1907 (Tiberi; introduced April 21, 2015); and H.R. 1916 (Levin; introduced April 21, 2015).
Laws currently authorizing the trade facilitation and enforcement functions of CBP (as outlined in
the Customs Modernization and Informed Compliance Act, Title VI of P.L. 103-182) emphasize a
balanced relationship between CBP and the trade community based on the principles of “shared
responsibility,” “reasonable care,” and “informed compliance.” Since the 9/11 terrorist attacks of
2001, Congress has placed greater emphasis on import security and CBP’s role in preventing
terrorist attacks at the border. Legislation addressing customs procedures and import security
includes the Homeland Security Act of 2002 (P.L. 107-296), the Security and Accountability for
Every (SAFE) Port Act of 2006 (P.L. 109-347), and the Implementing Recommendations of the
9/11 Commission Act of 2007 (P.L. 110-53).
CBP’s current import strategy emphasizes a risk management approach that segments importers
into higher and lower risk pools and focuses trade enforcement and import security procedures on
higher-risk imports, while expediting lower-risk flows. CBP’s “multi-layered” risk management
approach means that security screening and enforcement occur at multiple points in the import
process, beginning before goods are loaded in foreign ports (pre-entry) and continuing long after
the time goods have been admitted into the United States (post-entry).
How effectively CBP has performed its import policy mission is a matter of some debate. Some
participants in CBP’s “trusted trader” programs argue that the concessions (e.g., expedited
processing; fewer container inspections) CBP provides at the border do not adequately justify the
effort and expense to certify their supply chains. Questions have also been raised about CBP’s
management of trade facilitation, especially the means through which the Automated Commercial
System (ACS) trade data management system is being phased out in favor of the newer
Automated Commercial Environment (ACE). Some critics also assert that CBP has not
adequately fulfilled its trade enforcement role, especially its duties for preventing illegal
transshipments, protecting U.S. intellectual property rights, and collecting duties. Still others
criticize CBP’s performance of its security functions, especially because it does not yet physically
scan 100% of maritime cargo as mandated by the SAFE Port Act of 2006, as amended. In May
2014, DHS Secretary Jeh Johnson extended the deadline for an additional two years.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Introduction
International trade is a critical component of the U.S. economy, with U.S. goods trade amounting
to about $4 trillion in 2014, with merchandise imports of $2.4 trillion and exports of $1.6 trillion
(see Appendix B).1 The efficient flow of legally traded goods in and out of the United States is
thus a vital element of the country’s economic security. While U.S. trade in imports depends on
the smooth flow of legal cargo through U.S. ports of entry (POE), the goal of trade facilitation
often competes with two additional goals: enforcement of U.S. trade laws and import security.
How to strike the appropriate balance among these three goals is a fundamental question at the
heart of U.S. import policies.
Striking the appropriate balance among competing import policy goals is made more difficult due
to the volume and complexity of trade inflows. U.S. Customs and Border Protection (CBP), the
agency charged with managing the import process at the border, admitted about 30.4 million
import entries2 per year through over 300 U.S. POEs, in fiscal year (FY) 2013.3 The largest
volume of imports comes through land (truck and rail) and maritime flows, which together
account for over 25 million shipping containers per year. Air cargo consists mainly of lower
volume, higher value goods.4
This report describes and analyzes CBP’s role in the U.S. import process. (The report does not
cover CBP’s role in the U.S. export control system.) The first section of the report describes the
three overarching goals of U.S. import policy and the tension among them. Second, the report
summarizes recent legislative developments and provides a legislative history of customs laws,
followed by an overview of the U.S. import process as it operates today. Third, the import process
and CBP’s role in it are discussed.
Congress has a direct role in organizing, authorizing, and defining CBP’s international trade
functions, as well as appropriating funding for and conducting oversight of its programs. Thus,
the final section highlights several policy issues that Congress may consider in its oversight role
or as part of customs or trade legislation, including measures seeking to provide additional trade
facilitation benefits to importers and others enrolled in “trusted trader” programs, to improve
enforcement of intellectual property and trade remedy laws, to strengthen cargo scanning
practices, and/or to promote modernization of customs data systems, among other issues.

divided among sea (49%), air (23%), and land (26%) inflows, based on data presented in Table B-1. Although certain
issues raised in this report apply to the import process in general, this report focuses on containerized (as opposed to
bulk) goods, and does not address imports and exports in foreign trade zones. This report also does not address the
Transportation Security Administration’s role in air cargo security, which is discussed in CRS Report RL33512,

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Overarching Import Policy Goals
U.S. import policy seeks to balance three overarching policy goals. First, import policy promotes
trade facilitation. Trade facilitation refers to efforts to simplify and streamline international trade
procedures to allow for the easier flow of legitimate goods across international boundaries and
thereby to reduce the costs of trade.5 Trade facilitation includes the availability of advanced
customs rulings, transparent and efficient procedures, elimination of “red tape,” clear
information, effective communications, and cooperation between border agencies, among other
provisions.6
Trade facilitation is a priority for CBP and the trade community because trade represents a key
component of the U.S. economy. International trade accounts for about a quarter of the U.S.
economy, with merchandise trade (i.e., cargo) accounting for more than three-quarters of all U.S.
trade flows.7 Most economic research finds that while international trade may impose short-term
costs on certain sectors and industries that compete with imports, in the long run, trade promotes
efficiency, reduces costs to consumers, and increases economic growth due to competitive
advantage.8 With the production of goods increasingly organized into global supply chains, in
which the manufacture and final product assembly often occur in two or more countries,
intermediate components during the manufacturing process are a significant percentage of total
imports and exports in most countries, and a wide variety of U.S. manufacturers depend on the
efficient import and export of these inputs.9
Partly for this reason, trade facilitation has been a priority issue for the United States and its
international partners in organizations such as the World Trade Organization (WTO) and the
World Customs Organization (WCO), and in free trade agreement negotiations (FTAs). Within
the WTO Doha Development Round of multilateral trade negotiations, for example, the United
States has pursued “the shared objective of a rules-based, transparent, and efficient approach to
goods crossing the border.”10 In the WTO, the United States was instrumental in negotiating
binding disciplines on trade facilitation included in the December 2013 multilateral “Bali
Agreement.” The United States and other members of the WCO are encouraging the use of
electronic systems to expedite the clearance of merchandise entries and to ensure effective
customs controls, including the adoption of a “single window” data system through which
multiple cross-border regulatory agencies can clear merchandise entries (see “Interagency
Coordination”).11

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

There is an inherent tension between efforts to promote efficient trade flows, and a second goal of
U.S. import policy: the enforcement of trade laws designed to protect U.S. consumers and
business against illegal imports and to collect customs revenue. In general, U.S. trade laws seek
to protect U.S. consumers by enforcing health and safety standards, and to protect U.S. businesses
by enforcing patent, trademark, and copyright laws and by collecting anti-dumping and
countervailing duties (AD/CVD).12 Trade enforcement policies also govern the collection of
tariffs, fees, and taxes; CBP generated more than $36 billion in revenue in FY2013, including
more than $31 billion in customs duties.13
The third overarching goal of U.S. import policy is import security, or preventing the entry of
chemical, biological, radiological, and nuclear (CBRN) weapons and related material; illegal
drugs; and other contraband. While customs agencies have always played a role in protecting
public safety, including through narcotics enforcement in particular, the terrorist attacks of
September 11, 2001 (9/11), caused many Americans to place even greater emphasis on
transportation and port security. Thus, security measures enacted after 9/11 placed additional
responsibilities on customs officials to pro-actively prevent weapons of mass destruction and
other threats to the homeland from entering the United States and have made import security a
central feature of U.S. trade policy (see “Major Post-9/11 Import Security Legislation”). Import
security also has become an important feature of international efforts, and the United States and
its partners in the WCO have adopted new security protocols for tracking, inspecting, and
screening containerized imports and exports.14
Trade facilitation is in tension with trade enforcement and import security because trade
facilitation involves promoting faster and more efficient trade flows, while trade enforcement and
import security involve identifying and preventing illegal flows—tasks that often involve slower
cargo flows and reduced efficiency for the importer. These competing pressures make the
implementation of import policy a complex and difficult task, which CBP addresses through a
process of risk management, as described below (see “The Import Process”).
Many policy questions with respect to the import process concern how Congress and CBP
balance these three goals. Some U.S. importers and some in Congress have criticized CBP for
neglecting trade facilitation in favor of import security and trade enforcement. For example, some
in the trade community view the paperwork and additional reporting requirements imposed on
U.S. importers as overly burdensome, and they assert that these requirements run counter to U.S.
interests by threatening America’s economic security.15 Others argue that infrastructure issues,
scanning, and inspections at land ports of entry result in unacceptably long and unpredictable
border wait times. Delays have been described as particularly onerous at the U.S.-Mexico border,
where trade has increased more than sixfold since the North American Free Trade Agreement
(NAFTA) was implemented in 1994.16 Several studies have estimated the economic consequences

of border crossing delays, including a 2008 draft report by the Department of Commerce that
estimated that crossing delays at the U.S.-Mexico border resulted in $5.8 billion in lost economic
output, $1.4 billion in lost wages, 26,000 lost jobs, and $600 million in lost tax revenues—and
would result in losses twice this size by 2017.17 A review of nine additional studies concluded that
“one message comes through quite clearly—long and unpredictable wait times at the POEs are
costing the United States and Mexican economies many billions of dollars each year.”18
At the same time, others in Congress and in the trade community assert that the United States
may remain vulnerable to a terrorist attack against a port of entry—with potentially catastrophic
results—and that CBP should place greater emphasis on import security, even if the economic
costs are high. Some Members have expressed frustration, for example, that the great majority of
cargo containers are not scanned or physically inspected prior to arrival at a U.S. port.19 Similarly,
some manufacturers have alleged that CBP has not adequately investigated allegations of duty
evasion, product mislabeling, fraudulent country of origin declarations, or deliberate
misclassification of shipments;20 and some assert that their intellectual property rights (IPR) are
being violated by ever growing imports of counterfeit goods, and that CBP efforts in
collaboration with the private sector in identifying and enforcing IPR violations have been
inadequate.21 In short, how Congress and CBP balance trade facilitation, trade law enforcement,
and import security has important implications for homeland security, public safety, and virtually
every sector of the U.S. economy. To varying degrees, this tension underlies most aspects of U.S.
import policymaking.
Legislation in the 114th Congress
Several bills have been introduced in the 114th Congress to reauthorize CBP’s customs-related
activities, including S. 1269, the Trade Facilitation and Trade Enforcement Act of 2015 (Hatch;
introduced May 11, 2015); related bill H.R. 1907 (Tiberi; introduced April 21, 2015); and H.R.
1916 (Levin; introduced April 21, 2015). S. 1269 was reported by the Senate Finance Committee

on May 13, 2015; and H.R. 1907 was marked up and ordered reported by the House Committee
on Ways and Means on April 23, 2015.
In the Senate, on May 14, 2015, S. 1269 was incorporated into H.R. 644 (which was renamed the
Trade Facilitation and Trade Enforcement Act of 2015) and subsequently passed by a vote of 78-
20.
Title I of S. 1269,22 H.R. 1907, and H.R. 1916 would require CBP to, among other things, work
with the private sector and other federal agencies to ensure that all CBP partnership programs
provide meaningful trade benefits to program participants; require CBP to establish key
performance measures on modification; carry out facilitation and trade enforcement functions;
require CBP and Immigration and Customs Enforcement (ICE) to establish joint educational
seminars (with private sector input authorized) for enforcement personnel at POEs; and require
CBP and ICE, in consultation with federal agencies, other law enforcement agencies,
international organizations, and other interested parties, to develop and report to Congress on a
biennial joint strategic plan for trade facilitation and enforcement.
Title I would also authorize CBP programs, including customs modernization efforts such as the
Automated Commercial Environment (ACE) and the International Trade Data System (ITDS), the
Commercial Customs Advisory Committee (COAC), the Centers of Excellence and Expertise
(CEEs), and targeting and analysis groups to focus on each of CBP’s Priority Trade Issues (PTIs).
The Government Accountability Office (GAO) and CBP would also be required to report on CBP
improvements in areas including trade enforcement, tracking merchandise in-bond, and drawback
simplification.
Additionally, Title I of these bills would require CBP to strengthen internal controls, in part, by
developing criteria for assigning importer-of-record identification numbers; and would provide
CBP with the authority to strengthen enforcement controls over new importers, including
ensuring collection of duties, fees, and penalties through risk-based bonding. H.R. 1907 and H.R.
1916, in similar, but not identical language, would also require CBP to collect additional
information on “nonresident importers” and would require customs brokers to collect information
on the identity of importers.
Title II of S. 1269, H.R. 1907, and H.R. 1916 address import health and safety. Title II would
establish an interagency import safety working group, chaired by the Secretary of Homeland
Security. The group would be responsible for developing a joint import safety rapid response plan
to establish protocols and practices that CBP, in conjunction with other federal, state and local
authorities, must use when responding to cargo that poses a threat to the health or safety of U.S.
consumers. Title II also requires joint exercises with these entities and training for CBP port
personnel in enforcement of import health and safety laws.
Title III of S. 1269, H.R. 1907, and H.R. 1916 addresses intellectual property rights (IPR)
enforcement. First, Title III would amend customs laws to authorize and direct CBP (except in
cases that would compromise an ongoing law enforcement or national security investigation) to
share information with rights holders so that they could help to quickly identify whether a product

22 The text of S. 1269, Trade Facilitation and Trade Enforcement Act of 2015, was incorporated into H.R. 644 and
subsequently passed by the Senate. In order to differentiate between the House and Senate bills, however, this text
refers to the Senate bill as S. 1269.

entering the United States at a POE is in violation of a copyright or trademark. Second, CBP
would be authorized to seize merchandise if it is found to be in circumvention of IPR laws, and
would require CBP to notify an injured right holder if they are included on an annually revised,
CBP-maintained list. Third, the Secretary of DHS is directed to enforce copyrights on goods for
which the owner has submitted a copyright application in the same manner as if the copyright
were already registered. Title III would also establish a National Intellectual Property Rights
Coordination Center within CBP.
Title IV of S. 1269, and H.R. 1907, and Title V of H.R. 1916, address antidumping (AD) and
countervailing duty (CVD) evasion. One major difference between S. 1269 and H.R. 1907 is that
even though both bills would require the investigation of allegations of AD and CVD evasion
within specific deadlines and requirements, S. 1269 would require CBP to investigate the
allegations, while H.R. 1907 would require the Department of Commerce to carry out the
investigation.23 H.R. 1916 would assign primary investigative duties of AD/CVD evasion to CBP.
Also related to AD/CVD laws, H.R. 1907 would establish a Trade Remedy Law Enforcement
Division in CBP, direct CBP to identify evasion, authorize increased data sharing between CBP,
the Department of Commerce, and the U.S. International Trade Commission for enforcement
actions against evasion, and direct CBP to enter into agreements with customs officials in foreign
countries to increase cooperation in combatting evasion. H.R. 1907 would also require CBP to
assign sufficient personnel to prevent and investigate evasion, require CBP to submit an annual
report to Congress detailing evasion policies and activities, terminate the ability of new shippers
to post bonds during new shipper AD/CVD reviews, and require the Government Accountability
Office (GAO) to submit a report to Congress on the effectiveness of CBP efforts in investigating
and preventing AD/CVD duty evasion.
Title V of S. 1269 seeks to amend AD and CVD laws, in part, by clarifying and expanding the
methods that the International Trade Administration of the Department of Commerce (ITA) and
the U.S. International Trade Administration (USITC) may use to make determinations in
AD/CVD investigations. For example, Title V would clarify that the ITA, in cases in which an
exporter, manufacturer or producer of the targeted merchandise fails to cooperate by providing
information needed to calculate the duty rate, that the highest applicable dumping or subsidy rate
may be used. The amendment would also clarify and expand the calculation methods that the ITA
may use to calculate AD/CVD rates if there are particular market situations that may distort prices
or costs. Title V would also clarify the authority of the ITA to limit the number of foreign
exporters, manufacturers, or producers for which it calculates individual duty rates24 if it finds
that an investigation is unduly burdensome due to the complexity of the issues or information
presented, among other factors.
With regard to the USITC’s injury phase of AD/CVD investigations, Title V would amend the
definition of “material injury” to provide that a negative determination of material injury may not
be found solely on the basis of domestic industry profitability or recently improved performance.
The section would further expand the criteria that the USITC must use to evaluate the impact of

23 Antidumping (AD) and countervailing duty (CVD) laws are found in Title VII of the Tariff Act of 1930 (19 U.S.C.
1671-1677n). The International Trade Administration of the Department of Commerce (the administering authority in
the statute) investigates the existence and amount of dumping or subsidies, and the U.S. International Trade
Commission investigates material injury with respect to the U.S. industry petitioners.
24 Foreign exporters, producer, and manufacturers often request that their individual U.S. sales be calculated because
they could receive a lower duty rate than the overall AD/CVD rate.

investment, return on assets, and utilization of capacity.” Title V would also revise the “captive
production test” that the USITC must use to assess injury if the targeted product is a component
used in a downstream finished good.25
Title V of H.R. 1907 and Title VI of S. 1269 would also address additional trade enforcement
priorities by requiring the administration, in close consultation with Congress, to identify these
priorities and to more regularly consult with Congress on enforcement strategies. The
administration would be directed to address trade enforcement issues that, if eliminated, would
have the most impact on positive U.S. economic growth. The enforcement provisions in these
bills would also authorize the administration to reinstate the suspension of concessions under
Article 22 of the WTO dispute settlement agreement under certain conditions. The bills would
also require the USITC to provide an Internet-based database to provide information on the
volume and value of imports; and would require the Department of Commerce to provide reports
on quarterly changes in the volume and value of imports.
Title VI of the Senate customs bill would also establish a Trade Enforcement Trust Fund to be
used by the USTR and other agencies to enforce U.S. trade agreements and trade rights under the
WTO and U.S. free trade agreements (FTAs). The trust fund could also be used for trade capacity
building efforts. Title VI of S. 1269 would also require CBP and ICE to institute certain measures
to stop illegal honey transshipment; and require that the two agencies train and employ sufficient
personnel to detect, identify, and seize cultural property, archeological or ethnological materials,
and other fish, wildlife or plants that violate U.S. laws. Title VI would also codify the
establishment of the Interagency Trade Enforcement Center (ITEC).26
Regarding IPR enforcement, S. 1269 would add countries that deny adequate protection of trade
secrets to the USTR’s priority watch list, and require the USTR to develop an action plan for each
country that has been on the list for at least one year. S. 1269 would also establish at USTR a
Chief Innovation and Intellectual Property Negotiator with the rank of Deputy USTR.
Title VII of S. 1269 addresses issues regarding currency undervaluation. Among other things,
Title VII would require the ITA to investigate alleged currency undervaluation in AD/CVD
investigations and would provide a method for calculating the amount of undervaluation. The bill
would also require the administration to actively engage with those countries found to manipulate
exchange rates in order to urge implementation of monetary policies that would address the issue.
Title VIII of S. 1269 would provide a process for Congress, in conjunction with the USITC, to
receive and consider a miscellaneous trade bill (MTB) containing proposed duty suspensions and
reductions in 2015 and 2018. The process would require Congress to post on the Internet a
process for submission and consideration of proposed duty suspensions for possible inclusion in
the MTB, and also require the USITC to publish in the Federal Register and on the Internet a
notice requesting MTB submissions from the public.27

25 Captive products are items designed specifically for use with another product. Many captive products are necessary
to the function of the core product. For example, a razor cannot function without blades (a captive product).

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Title IX of S. 1269, Title VI H.R. 1907 and Title IV of H.R. 1916 address miscellaneous customs
provisions. All three bills would raise the de minimis value (currently $200) for unaccompanied
cargo to $800.28 The bills would also require DHS to consult with Congress no later than 30 days
after proposing and 30 days prior to finalizing, any DHS policies, initiatives, or actions that
would have a major impact on trade and customs revenue functions. Other provisions include
adding committing or conspiring to commit an act of terrorism to the list of offenses that are
grounds for removal of a customs broker’s license, amending Harmonized Tariff Schedule
chapter 98 to reduce the record-keeping burden on U.S. goods entering without improvement
abroad, and allowing for the subtraction of the value of U.S. components assembled in goods that
are exported and returned after being improved abroad. Miscellaneous provisions also include
making bulk cargo residue exempt from duty and implementing drawback simplification. All
three bills would eliminate the “consumptive demand” exception to the prohibition on
importation of goods made with convict, forced, or indentured labor.29 As passed in the Senate, S.
1269 would also provide offsets for the proposal by temporarily extending an increased customs
user fee, among other things.
Legislative History of U.S. Customs and Trade
Facilitation, Enforcement, and Import Security
Policies

The U.S. Customs Service (USCS),30 the agency historically responsible for trade facilitation and
enforcement, was established by an act of Congress on July 31, 1789 (1 Stat. 29), and on
September 2, 1789, was placed under the Secretary of the Treasury.31 At that time, the primary
role of the service was to collect U.S. customs tariffs, which were the major revenue source for
the U.S. government until the federal income tax was established in 1913. Key laws establishing
and authorizing the trade functions of the USCS included provisions in the Tariff Act of 1930,32
the Customs Simplification Act of 1953,33 and the Reorganization Plan of 1965.34
More recent customs legislation can be categorized into two components. The first is focused on
the Customs Service’s traditional role of trade facilitation and enforcement, and the second,
which emerged following the 9/11 terrorist attacks, has focused on the issue of import security.
The Homeland Security Act (P.L. 107-296) placed all or parts of 22 different federal departments

28 The de minimis value level (19 U.S.C. 1321, as amended), is the value threshold below which unaccompanied
shipments may enter U.S. commerce without the need for formal entry procedures or payment of customs duties.
29 Section 307 of the Tariff Act of 1930 (19 U.S.C. 1307), as amended, prohibits the importation of goods made by
convict labor, forced labor, child labor, and indentured labor. The law, however, excludes products that “are not mined,
produced, or manufactured in such quantities in the United States as to meet the consumptive demands of the United
States.
30 In this report, the U.S. Customs Service or USCS is used to refer to the legacy customs agency (before the Homeland
Security Act of 2002 and the subsequent reorganization modification plan changed the name of the agency). When
referring to legislation after 2002, Customs and Border Protection, or CBP, is used.

and agencies, including the Customs Service, into the Department of Homeland Security (DHS).35
DHS’s bureau of Customs and Border Protection (CBP) has been the lead agency facilitating,
enforcing, and securing trade flows since 2003.
Major Trade Facilitation and Enforcement Legislation
The last time that the then-USCS’s trade functions were fundamentally reorganized was in 1993,
in Title VI of the North American Free Trade Agreement Implementation Act (P.L. 103-182), also
known as the Customs Modernization and Informed Compliance Act, or “Mod Act.” Other major
legislation addressing these functions was Title IV of the Security and Accountability For Every
(SAFE) Port Act of 2006 (P.L. 109-347) that addressed trade facilitation and enforcement by
reorganizing DHS’s trade functions, requiring increased interaction with the trade community,
and providing for greater congressional oversight.
The “Mod Act” of 1993 (Title VI of P.L. 103-182)
The Mod Act, implemented on December 8, 1993, amended many sections of the Tariff Act of
1930 that applied to USCS’s role in trade enforcement. The law was the culmination of a multi-
year effort among Congress, the USCS, and the Joint Industry Group (a coalition of private-sector
firms involved in international trade), to develop legislation on Customs modernization.36 While
the main purpose of the law was to streamline, automate, and modernize USCS’s commercial
operations, the law was also intended to improve compliance with U.S. customs laws, and to
provide safeguards, uniformity, and due process rights for importers.37
The Mod Act addressed the tension between trade facilitation and trade enforcement by replacing
the historical “agency-centric” model of trade enforcement with a “shared responsibility”
approach.38 Thus, whereas USCS previously had monitored imports and determined the level of
customs duties owed by each importer, under the shared responsibility approach USCS (now
CBP) is required to inform importers of their rights and responsibilities under the customs
regulations and related laws; and importers of record are required to be aware of their legal
obligations and to make their own duty determinations through the concept of “informed
compliance.”39 Importers are also required to exercise “reasonable care” when classifying and

38 The previous model employed by USCS resembled utility companies’ billing model, which measures usage and
sends customers a statement; while the current model resembles tax collection by the Internal Revenue Service, which
requires businesses and individuals to estimate their own tax liabilities.
39 NAFTA Report, p. 106. In meeting the “reasonable care” standard, House lawmakers suggested that importers
consider using assistance when bringing products into the United States. These aids could include seeking advance
rulings from Customs, consulting with a customs broker or trade attorney, using in-house employees with a knowledge
of customs laws, or obtaining analyses from accredited labs (NAFTA Report, p. 120).

determining the value of imported merchandise. If importers have questions about the country of
origin, classification, or valuation of merchandise, they may apply to CBP for a binding
determination (known as a customs ruling) prior to importation.40
The Mod Act placed a greater administrative burden on the importer, and shifted USCS’s focus to
the collection of data and post-entry enforcement (i.e., audits) to ensure that all legal requirements
have been met.41 By reducing USCS’s role in duty determination, the act freed up agency assets
to modernize the import process and improve post-entry enforcement.42 Private industry
stakeholders accepted these increased responsibilities because the law also provided for a quicker
and more transparent import process through streamlined and automated customs operations.
Title IV of the Security and Accountability for Every (SAFE) Port Act of 2006
(P.L. 109-347)

Title IV of the SAFE Port Act addressed the organization, management, and oversight of CBP
enforcement functions. Title IV required DHS to designate a senior official to ensure the
coordination of the trade and customs revenue functions in DHS and with other federal
departments and agencies; and that CBP’s trade functions were not diminished and kept pace with
the level of trade entering the United States.
Title IV also required additional consultation with representatives of the business community,
including CPB’s Commercial Operations Advisory Committee (COAC) on DHS policies and
actions that could have significant impact on international trade and customs revenue functions;
and established an Office of International Trade (OIT) within CBP; required DHS, the U.S. Trade
Representative (USTR) to work through the World Trade Organization (WTO), the World
Customs Organization (WCO), and other international organizations to align customs
requirements to the extent possible to facilitate the efficient flow of international trade.
Title IV also authorized the establishment of the International Trade Data System (ITDS) as part
of the Automated Commercial Environment (ACE), CBP’s interactive customs data management
system. ITDS is an intergovernmental project to coordinate and standardize the collection of trade
enforcement data by creating a single portal for the collection and distribution of import and
export data to be used by all 48 federal government agencies that play a role in trade enforcement.
The section required all federal agencies involved in trade enforcement to participate in the ITDS.
Major Post-9/11 Import Security Legislation
While previous customs legislation focused on the tension between trade facilitation and
enforcement, the 9/11 attacks focused America’s attention on homeland security. With the attacks
having been executed by foreign nationals traveling on commercial aircraft, an immediate priority
was to reorganize existing law enforcement resources related to immigration, transportation,
trade, and border security into a new federal Department of Homeland Security (DHS). At least

six laws enacted between 2002 and 2007 included provisions related to the trade process and
made import security a central feature of U.S. trade policy.
Trade Act of 2002 (P.L. 107-210)
Customs reauthorization legislation in the Trade Act of 2002 (Title III of P.L. 107-210, the
Customs Border Security Act of 2002) authorized appropriations for a number of noncommercial
and commercial CBP programs as well as CBP’s air and marine interdiction program. Funds were
also authorized to be appropriated for the Automated Commercial Environment (ACE; see “Pre-
Entry: Advanced Cargo Screening, Scanning, and Inspections”), for equipment and programs for
drug enforcement, and for the detection of terrorists and illicit narcotics along the U.S borders
with Mexico and Canada, and in Florida and Gulf Coast seaports.
The Trade Act also included one of the most significant additions to the customs clearance
process since 9/11: a requirement that importers and exporters submit advance cargo manifest
information prior to cargo arriving at a U.S. port of entry (POE). The law authorized the Secretary
of the Treasury to publish regulations requiring the submission of this information, and directed
the Secretary to consult with a broad range of import and export stakeholders and to base the
regulations on the Secretary’s determination of what is “reasonably necessary to ensure aviation,
maritime, and surface transportation safety and security.”43 CBP uses this advance cargo
information to conduct risk-based targeting through the Automated Targeting System (ATS; see
“Automated Targeting System”).
Maritime Transportation Security Act of 2002 (P.L. 107-295)
The Maritime Transportation Security Act of 2002 (MTSA, P.L. 107-295) expanded DHS’s
authority under the Trade Act of 2002 to collect and share advance cargo data, and took several
steps to strengthen port security.44 Section 102 of the MTSA established a new chapter of the U.S.
Code (46 U.S.C. 701) to establish DHS’s overall role in port security. Among other things, the
law required DHS to assess vessel and port security and to develop national and regional
maritime transportation security plans,45 required certain ports and vessels to develop security and
incident response plans to be approved by DHS,46 and established a Department of Transportation
grant program to help ports implement their security plans.47
The MTSA also established new security requirements for U.S. and foreign ports and for ships
operating in U.S. waters. Within the United States, the law required DHS to establish regulations
to prevent individuals from entering secure areas of vessels or ports unless the individuals hold
security cards. The port security cards are known as Transportation Worker Identity Credential
(TWIC) cards, and are administered by the Transportation Security Administration (TSA) along

with the U.S. Coast Guard.48 With respect to foreign ports (where Congress has no direct
authority), the law required DHS to assess port security at foreign ports and to notify foreign
ports if they are found to lack appropriate counter-terrorism measures.49 DHS is authorized to
restrict the entry of vessels arriving from foreign ports that fail to maintain effective counter-
terrorism measures.50 With respect to ships and other vessels operating in U.S. waters, the law
required that certain vessels be equipped with an automatic identification system while operating
in U.S. waters, and that DHS also develop and implement a long-range automated vessel tracking
system for certain vessels.51
Homeland Security Act of 2002 (P.L. 107-296)
The Homeland Security Act of 2002 (HSA, P.L. 107-296) created a framework for the transfer of
all or part of 22 different federal departments into the Department of Homeland Security (DHS),
including the USCS and the U.S. Coast Guard.52
Title IV of the act created within DHS a Directorate of Homeland Security headed by the Under
Secretary for Border and Transportation Security.53 The directorate was given responsibility for
preventing the entry of terrorists and the instruments of terrorism into the United States, and for
ensuring the speedy, orderly, and efficient flow of lawful traffic and commerce, among other
things. Title IV also established the U.S. Customs Service and the office of the Commissioner of
Customs within DHS.54 The act specified that certain customs revenue functions would be
retained by the Secretary of the Treasury, who may delegate the authority to the Secretary of
Homeland Security.55 Although the customs inspection and enforcement authority of the former
USCS were transferred to CBP, Section 412(b) of the HSA mandated that DHS could not
“consolidate, discontinue, or diminish” the trade and customs revenue functions of the USCS, or
reduce staffing levels or the resources attributable to these functions.56
The HSA directed the President, no later than 60 days after enactment of the act, to transmit to the
appropriate congressional committees a reorganization plan for the transfer of agencies,
personnel, assets, and obligations to the new Department of Homeland Security.57 The President

submitted an initial plan on November 25, 2002,58 and modified the plan shortly thereafter
following consultation with then Secretary of Homeland Security designate Tom Ridge.59 In the
modification plan, the USCS was renamed the Bureau of Customs and Border Protection (CBP),
and the Bureau of Border Security was renamed the Bureau of Immigration and Customs
Enforcement (ICE).60
Coast Guard and Maritime Transportation Act of 2004 (P.L. 108-293)
The Coast Guard and Maritime Transportation Act of 2004 (P.L. 108-293) contained a number of
maritime security provisions that amended the MTSA. Title VIII of the law added security
requirements to the import process provisions, including amendments to certain long-range vessel
tracking system requirements.61 DHS was also required to submit a plan for implementation of a
maritime intelligence system (previously authorized in the MTSA) to incorporate information on
vessel movements and assign incoming vessels a terrorism risk rating.62
Section 808 of the law required the Department of Transportation to “conduct investigations, fund
pilot programs, and award grants” to examine and develop certain equipment to enhance the
investigative ability of CBP, including equipment to accurately detect nuclear, chemical, or
biological materials; and tags and seals equipped with sensors that are able to track marine
containers throughout their supply chains and to detect hazardous and radioactive materials
within containers.63
The law also required DHS to report on several cargo import security issues, including the costs
to the government of vessel and container inspections, plans for implementing secure systems of
transportation, progress on the installation of radiation detectors at all major U.S. seaports, the
willingness of foreign seaports to utilize non-intrusive inspection (NII) techniques to inspect
cargo bound for the United States, and evaluation of the existing cargo inspection targeting
system for international intermodal cargo containers.64

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Security and Accountability For Every (SAFE) Port Act of 2006 (P.L. 109-347)
On July 22, 2004, the National Commission on Terrorist Attacks Upon the United States (the 9/11
Commission) published its report on the circumstances surrounding the 9/11 attacks and made
recommendations to guard against future attacks. The report expressed concern that the United
States lacked “a forward-looking strategic plan” that devoted adequate attention to maritime and
surface transportation.65
Congress responded by passing the Security and Accountability For Every Port Act of 2006
(SAFE Port Act, P.L. 109-347) and the Implementing Recommendations of the 9/11 Commission
Act of 2007 (The 9/11 Act, P.L. 110-53). Title I of the SAFE Port Act focused on port security.
The act updated several deadlines from previous legislation, including a deadline of April 1,
2007, for DHS to implement a long-range vessel tracking system,66 and a deadline of January 1,
2009, for issuing TWIC cards and for all ports to implement TWIC readers.67 In addition, the act
required by December 31, 2008, that all containers entering U.S. ports be subject to radiation
detection scanning.68
Title II of the SAFE Port Act focused on international supply chain security, defined by Section 2
of the act as the “end-to-end process for shipping goods to or from the United States beginning at
the point of origin (including manufacturer, supplier, or vendor) through a point of distribution to
the destination.” The Title includes five main provisions with respect to maritime cargo security,
which are summarized here and discussed in greater detail below:
• Section 203 authorized cargo to be screened through CBP’s Automated Targeting
System (ATS; see “Automated Targeting System”) and further authorized DHS to
require advanced electronic cargo data (see “Advance Electronic Cargo
Information”) as needed to improve ATS targeting.69
• Section 205 authorized the Container Security Initiative (CSI; see “Import
Security Scanning and Inspections”), designed “to identify and examine or search
maritime containers that pose a security risk before loading such containers in a
foreign port for shipment to the United States.” The section authorized DHS to
designate particular foreign seaports to participate in the CSI, and directed DHS
to establish criteria and procedures for nonintrusive inspection (NII) and for
nuclear and radiological detection systems at CSI ports.70

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

• Sections 211-223 authorized the Customs-Trade Partnership Against Terrorism
(C-TPAT; see “Trusted Trader Programs”) and set forth C-TPAT program
parameters. C-TPAT is a voluntary program that allows certain trade-related
firms to be certified by CBP as having secured the integrity of their supply
chains. The law established three tiers of C-TPAT membership, and described
potential membership benefits associated with each.71
• Section 231 directed DHS to establish pilot programs in three foreign seaports to
conduct NII and radiation detection scanning of cargo containers. Beginning one
year after enactment of the act (i.e., by October 2007), the section required that
DHS scan 100% of containers destined for the United States loaded in the three
pilot ports and that questionable or high-risk cargo be identified for further
inspection.72 The program is known as the Secure Freight Initiative (SFI; see
“Import Security Scanning and Inspections”).
• Section 232 required that 100% of cargo containers originating outside the
United States and imported into the United States be screened by DHS to identify
high-risk containers. As enacted, the section required DHS to ensure that
containers identified as high risk during the screening process also be scanned
through NII and radiation detection equipment before they arrive in the United
States (see “100% Scanning Requirement”).73
Implementing Recommendations of the 9/11 Commission Act of 2007
(P.L. 110-53)

The 9/11 Act of 2007 included two provisions with respect to the import process. Section 1602 of
the 9/11 Act required, by August 3, 2010, that 100% of air cargo bound for the United States or
traveling within the United States be subject to scanning or inspection commensurate with
standards established for passenger checked baggage.74
Section 1701 of the 9/11 Act amended the SAFE Port Act to require by July 1, 2012, that 100% of
maritime containers imported to the United States—that is, whether or not they are identified as
high-risk during the ATS screening process—be scanned by NII and radiation detection
equipment before being loaded onto a vessel in a foreign port. The act authorized the secretary of
DHS to extend the deadline by two years, and in additional two-year increments, by certifying
that scanning systems are not available, are insufficiently accurate, cannot be installed, cannot be
integrated with existing systems, will significantly impact trade and the flow of cargo, and/or do
not provide adequate notification of questionable or high-risk cargo (see “100% Scanning
Requirement”).75

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

The Import Process
Under the Homeland Security Act of 2002 (P.L. 107-296) as amended in 2003, CBP is the lead
agency charged with enforcing the trade laws under the Mod Act and the security measures under
the MTSA, the SAFE Port Act, and the other post-9/11 laws. CBP’s trade strategy emphasizes
risk management, which means that CBP collects advance information about shippers, importers,
and cargo to evaluate cargo for potential import security and trade enforcement risks, and focuses
enforcement efforts primarily on cargo and shippers identified as relatively high risk.76
Conversely, those deemed lower-risk imports (including, e.g., shipments of “trusted traders”) are
less likely to be targeted for CBP enforcement and may be eligible for expedited processing—
thus advancing CBP’s trade facilitation goal and freeing up resources for targeting higher-risk
imports.
Import Security and Trade Enforcement Terminology and Procedures
As discussed throughout this report, cargo being imported to the United States may be subject to multiple and varied
types of import security and trade enforcement reviews, including the fol owing:

Screening: A risk assessment based on an analysis of data elements (e.g., cargo manifest, country of origin,
shipper and consignee information) provided by an importer or carrier.

Scanning: An analysis of container contents based on non-intrusive inspection (NII) technologies, including
x-ray and gamma ray imaging systems and other technologies. NII scanning produces a high-resolution image of
container contents that is reviewed by law enforcement officers to detect hidden cargo and other anomalies that
suggest container contents do not match reported manifest data. If an officer detects an abnormality, containers
may be “cracked open” for a physical examination. Scanning may also refer to radiation detection.

Radiation detection: An analysis of container contents based on radiation portal monitors, handheld radiation
detection monitors, and/or other radiation detection technology to detect nuclear material that may be part of a
nuclear weapon or dirty bomb.

Examination: A physical examination of container contents (requires that the container be opened and, in
some cases, unpacked).

Primary inspection: A review of entry documents to determine whether cargo may be admissible to the
United States.

Secondary inspection: A review of container contents to confirm that cargo is admissible to the United
States. Secondary inspections may include NII scanning and/or a physical examination of container contents.

Liquidation: The final assessment of import-related taxes and fees; typically occurs a year or more after cargo
enters the United States.
Source: CRS analysis of the SAFE Port Act of 2006 (P.L. 109-347) and CBP briefing materials.
CBP’s trade strategy also emphasizes layered enforcement, meaning that risk assessment and risk-
based enforcement happen at a number of different points in the import process, beginning well
before cargo arrives at a U.S. port of entry, and continuing long after cargo has been formally
admitted to the United States. CBP attempts to target high-risk flows as early as possible in the
import process, but its ability to conduct enforcement activities at different stages of the import
process is designed to create multiple opportunities to interdict illegal imports.
The import process includes three main stages, as illustrated in Figure 1. First, prior to entry at a
U.S. POE, importers and carriers file paperwork and provide advance electronic cargo

information, and all imports are subject to risk-based screening. Based on the results of this
screening, certain goods are subject to import security scanning and inspection in foreign ports
and/or upon arrival at a U.S. port. Second, importers file “entry documents” when cargo reaches a
U.S. port, and cargo may be subject to additional scanning and inspection for import security and
trade enforcement purposes. Admissible cargo is released from the port, and importers file an
additional set of “entry summary” documents, which CBP uses to calculate customs duties and to
make an initial assessment of taxes, fees, and duties owed. Third, following cargo entry, importers
may challenge the assessment for up to a year, or longer under certain circumstances, until the
final assessment of taxes and fees, a process known as liquidation. Trade enforcement activities
may continue through audits and other post-entry investigations.
Figure 1. The U.S. Import Process

Source: CRS presentation of information provided by CBP.
Notes: Import security includes screening, scanning, and inspections to detect chemical, biological, radiological,
and nuclear (CBRN) weapons, il egal drugs, and other contraband; trade enforcement includes screening,
scanning, and inspections to detect trademark and copyright violations, unsafe products, and illegal agricultural
products, and to ensure proper collection of tariffs, fees, and anti-dumping and countervailing duties (AD/CVD).
Pre-Entry: Advanced Cargo Screening, Scanning, and Inspections
The import process begins well before cargo arrives at a U.S. port of entry (POE). During the pre-
entry stage of the process, importers of record submit electronic cargo manifests and other
shipment data to CBP. This information may be submitted through CBP’s Automated Customs
System (ACE) or its Automated Customs Environment (ACE; see “Text Box: CBP’s Data
Management Systems,” below). CBP uses these advanced filing data to pre-clear cargo for
admission, facilitate inflows, and target certain cargo for import security and trade enforcement.
Cargo may be subject to import security scanning and inspections in foreign ports prior to being
loaded on U.S.-bound ships and/or upon arrival at a U.S. port of entry (POE).

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

CBP’s Data Management Systems
Each stage of the import process involves an ongoing exchange of information between CBP and importers. CBP
manages two systems for tracking this information and for managing the col ection of import duties and other trade-
related fees: the Automated Commercial System (ACS) and the Automated Commercial Environment
(ACE)
. Both of these systems serve as data management systems for CBP and as contact points for trade partners to
submit electronic data to CBP, to receive information about the status of their shipments, and to make payments and
manage customs accounts.
The ACS began operating in 1984 and relies on mainframe computer hardware and software that are considered at
least a generation out of date, factors which reportedly limit ACS functionality and reliability. The U.S. Customs
Service created ACE in 2001 to begin replacing ACS, a transition known as “customs modernization.” The challenge
in the customs modernization process is to create a new data management system that meets all of CBP’s trade
enforcement and import security needs, while supporting a streamlined import process for legitimate importers, and
to test and implement the new system without disrupting trade flows during the transition period.
To this end, CBP has initiated ACE as a series of modules that encompass discrete phases of the import process. In
general, as new ACE modules are introduced, importers initially are permitted to use either ACS or ACE for the
affected task; and once the new ACE component has been tested and proven effective, importers are required to use
the ACE components as certain ACS functions are disabled. CBP’s eventual goal is to eliminate the ACS, and for ACE
to provide a single point-of-access and data management system covering the entire trade process for al U.S.
importers.
According to CBP’s office of legislative affairs, trade users may use their ACE accounts to pay duties and fees and to
generate 125 downloadable and customized reports. As of March 2012, electronic manifest data for truck, rail, and
ocean shipments may be filed through ACE at al U.S. POEs. Air and multi-modal integration is anticipated, but not yet
planned. On September 29, 2012, ACE became the only CBP-approved Electronic Data Interchange (EDI) for
submitting rail and sea manifests.
On October 18, 2014, CBP added a new ACE Automated Brokers Interface (ABI) query capability to request entry
record status, cargo and manifest information on file with ACE. On January 3, 2015, a series of new ACE capabilities
were launched including the transmission of antidumping and countervailing duty entries; electronic bond processing
for both Single Transaction Bonds and Continuous Bonds; and the deployment of an import air manifest. CBP plans
on completing trade processing capabilities in ACE and decommissioning similar capabilities in its other system by the
end of 2016.
CBP is working to transition cargo processing to the ACE, which is being developed as the primary system CBP and
all federal partner government agencies (PGAs) will use as a “single window” to track, control, and process all
imported and exported goods. To that end, CBP has announced three key dates. On May 1, 2015, CBP will require
mandatory use of ACE for all electronic manifest filing. On November 1, 2015, use of ACE will be mandatory for all
electronic cargo release and related entry summary filing. On October 1, 2016, all remaining electronic portions of
the CBP cargo process will be required to be completed through ACE.

Deployment D–January 2015 Release Capabilities for the Trade Community”.
Trusted Trader Programs
One of CBP’s primary tools for risk management is the use of trusted trader programs, including
the Customs-Trade Partnership Against Terrorism (C-TPAT), which was established in November
2001, after the 9/11 attacks, and subsequently authorized as part of the SAFE Port Act of 2006
(see “Security and Accountability For Every (SAFE) Port Act of 2006 (P.L. 109-347)”). Trusted
trader programs are voluntary public-private partnership programs that permit certain import-
related businesses to register with CBP, follow instructions prescribed by the agency to secure
their supply chains, and thereby become recognized as low-risk actors and become eligible for
expedited processing and other benefits. These programs are described in greater detail in the text
box below.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

CBP Trusted Trader Programs
Customs-Trade Partnership Against Terrorism (C-TPAT)

C-TPAT is open to U.S. importers, customs brokers, and port and terminal operators; Mexican and Canadian
manufacturers and certain other foreign manufacturers; rail, sea, air, and truck carriers; and U.S. consolidators
and certain other logistics providers.

Businesses may apply to join C-TPAT by filling out an on-line application and submitting a supply chain security
profile that meets or exceeds minimum standards established by CBP. The security profile includes a narrative
description of measures in place to ensure the security of cargo at all stages of the company’s supply chain,
including procurement, production, packing, storage, loading, and transportation of goods for import. CBP
reviews profiles within 90 days and reviews company compliance histories. Upon a favorable review, the
company is certified as a Tier I C-TPAT partner.

Within one year of a C-TPAT partner being certified, CBP conducts a physical examination of the company’s
supply chain to validate that the security measures described in the profile are in place. Companies that meet
minimum security criteria are validated as Tier II C-TPAT partners, and companies that show a sustained
commitment beyond minimal security expectations are validated as Tier III partners.

Membership in C-TPAT reduces an importer’s ATS risk score, with greater reductions for Tier II and Tier III
members. C-TPAT members are less likely than non-members to be selected for security or trade related
scanning.

Certified C-TPAT members are also eligible for expedited processing at POEs and for expedited treatment when
containers are selected for scanning or inspection. C-TPAT permits stratified exams, so that if an entry with
multiple line items is selected for secondary inspection, only the selected container(s) are detained for
inspection, minimizing importers’ storage costs. (For non-C-TPAT members, multiple containers may be delayed
when a single container must be examined.) CBP’s business-resumption plans also cal for C-TPAT members to
have front-of-the-line privileges in the event of a future port closure.

As of September 30, 2013, over 10,662 trade partners were certified as C-TPAT members and 2,235 companies
were validated or re-validated in FY2013, according to CBP.
Free and Secure Trade System (FAST)

FAST is open to commercial truck drivers who have completed background checks and fulfill eligibility
requirements and whose imports have supply chains that are fully C-TPAT certified.

FAST members are eligible to use dedicated FAST lanes at certain land POEs. FAST lanes generally have shorter
wait times and faster processing.

More than 78,000 commercial drivers are enrol ed in the FAST program, and 17 ports at the northern and
southern borders have FAST lanes.
Importer Self-Assessment Program (ISA)

The ISA is open to C-TPAT members who are residents of the United States, have a two-year import history,
and are known importers that have businesses physical y established, located, and managed within the United
States.

Importers must demonstrate a willingness to maintain an ongoing, mutually beneficial trade relationship with
CBP, the ability to manage and monitor their ongoing compliance with trade laws through self-assessment, and
the willingness to demonstrate an ongoing compliance through internal controls and annual risk assessments.

Accepted ISA importers are assigned a National Account Manager who serves as a liaison between CBP and the
importer, and identifies and resolves issues through consultation.

ISA members receive guidance from CBP upon request and are exempted from the comprehensive audit pool
known as Focused Assessment Audit (single issue audits may be conducted to address specific concerns).

As of November 17, 2014, CBP reports that 308 companies participate in the Importer Self-Assessment
Program, accounting for 23% of U.S. imports by value.
Mutual Recognition Arrangements

As of June 27, 2014, CBP has established mutual recognition arrangements with Canada, the European Union,
Israel, Japan, Jordan,, Mexico, New Zealand, South Korea, and Taiwan.77 These arrangements allow C-TPAT
members and trusted traders to receive similar benefits in partner countries as those in the United States.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Advance Electronic Cargo Information
Under the Trade Act of 2002, as amended, importers and carriers seeking to import goods to the
United States must provide DHS with electronic manifest and other data prior to arrival in U.S.
ports. Carriers are required to provide names and addresses of shippers and consignees, detailed
descriptions of the goods being imported, information about the carrier, and information about the
day, time, and port of arrival. Specific filing requirements differ by mode of entry (truck, rail,
maritime, or air) and in some cases by country of origin (see text box below).

Deadlines for Submission of Electronic
Manifests and Other Shipping Data
Air Cargo (North America, Caribbean, Central America, and South America north of equator): Prior to aircraft
departure bound for the United States (wheels up)
Air Cargo (Other countries of origin): 4 hours prior to arrival
Rail Cargo: 2 hours prior to arrival
Truck Cargo: 1 hour prior to arrival, or 30 minutes prior to arrival for C-TPAT members
Maritime Cargo: Importer data due 24 hours before cargo is loaded on vessel bound for the United States; carrier
data due 24 hours prior to loading in a foreign port for containerized and break-bulk cargo or 24 hours prior to
arrival at the first U.S. port for bulk cargo, with updates as they occur.
Source: 19 C.F.R. §§4, 122-123.
Maritime Cargo: 10 + 2 Importer Security Filing
Maritime cargo is subject to additional reporting requirements under Section 203 of the SAFE
Ports Act and an interim final rule published by CBP on November 25, 2008.78 Under the rule,
maritime vessels must submit Importer Security Filings (ISF) and Additional Carrier
Requirements known collectively as “10 + 2” filings—so-called because they include 10 data
elements to be submitted by importers of record, plus 2 data elements to be submitted by carriers.
The 1079 data elements supplied by importers are
1. importer of record number;
2. consignee number;
3. seller name and address;
4. buyer name and address;
5. ship-to party name and address;
6. manufacturer (supplier) name and address;
7. country of origin;
8. Harmonized Tariff Schedule (HTS) 6-digit classification;

78 P.L. 109-347 §203; 19 C.F.R. §§4.7–4.7d; also see 73 Federal Register 71730.
79 Ten data elements are required for all maritime cargo destined for U.S. entry. If cargo is transiting through the United
States, only five elements are required: booking party name/address; ship to party; harmonized tariff schedule (HTS)
classification; foreign port of unlading; and place of delivery.

9. container stuffing location; and
10. consolidator (stuffer) name and address.
The two data elements provided by carriers are
1. the vessel stow plan; and
2. daily messages with information about any changes in container status.80
The first 8 importer data elements must be provided 24 hours prior to lading of the goods on a
vessel. Information on the stuffing location and the consolidator must be filed as soon as possible,
but no later than 24 hours before arrival in the United States. Regarding the carrier data, the
vessel stow plan must be provided no later than 48 hours after departure, and container status
messages must begin within 24 hours of creation or receipt of the container.
Automated Targeting System
Electronic manifests and other advanced data elements (including the 10+2 data elements
mentioned above) are forwarded to CBP’s Automated Targeting System (ATS). CBP officers
screen imports by comparing cargo and conveyance information against intelligence from CBP’s
National Targeting Center (NTC) and other intelligence and law enforcement databases. The ATS
assigns every incoming container a risk-based score related to weapons of mass destruction,
narcotics, and other contraband, as well as for the potential for commercial fraud, and other
customs violations.81 The rule-sets for assigning risk scores are designed to identify suspicious
activity or behavior and are updated on an ongoing basis in response to changes in intelligence
and previous enforcement records.
Import Security Scanning and Inspections Abroad
The SAFE Port Act of 2006 authorizes a pair of programs to conduct radiation detection and NII
scanning in foreign ports: the Secure Freight Initiative and the Container Security Initiative.
Secure Freight Initiative (SFI)
The Secure Freight Initiative (SFI) is a pilot program to test CBP’s ability, working with
international partners, to conduct radiation detection and NII scanning of 100% of cargo
containers being loaded on U.S.-bound ships in certain ports. The SFI employs an integrated
scanning system consisting of radiation portal monitors (provided by the Department of Energy)
and NII imaging systems (provided by CBP) in a single location. CBP officers review the

80 U.S.CBP, “Fact Sheet: New Cargo Security Requirements for Maritime Carriers and Importers,” November 24,
2008. Also see U.S. Government Accountability Office, Supply Chain Security: CBP Has Made Progress in Assisting

81 The ATS includes modules for inbound cargo and conveyances; outbound cargo and conveyances; air, ship, and rail
passengers; private vehicle land passengers; international cargo outside the United States; and a trend analytic module.
Only the inbound cargo and conveyance module is discussed in this report, though some features of the ATS are
common to more than one module.

scanning data to determine which containers should be subject to secondary inspections.
Secondary inspections, when called for, are conducted by host-state law enforcement agencies.
In 2007, Section 1701 of the Implementing Recommendations of the 9/11 Commission Act of
2007 (9/11 Act; P.L. 110-53) amended the SAFE Port Act to require that by July 1, 2012, 100% of
maritime containers imported to the United States—that is, from all ports, whether or not they are
identified as high-risk—be scanned by NII and radiation detection equipment before being loaded
onto a U.S.-bound vessel in a foreign port. Pursuant to law, the program began operation operated
in three foreign ports in 2007: Port Qasim in Pakistan, Puerto Cortes in Honduras, and
Southampton in the United Kingdom. The pilot was also subsequently implemented on a limited
basis in the larger ports of Port Salalah in Oman, Port Busan in South Korea, and Singapore.
Following DHS’s evaluation of the program, however, the program was scaled back and currently
operates only in Port Qasim.82
On May 2, 2012, however, then-DHS Secretary Janet Napolitano notified Members of Congress
that she would exercise her authority under the 9/11 Act to extend the deadline for 100%
scanning.83 In May 2014, DHS Secretary Jeh Johnson extended the deadline for an additional two
years.84 In the May 2014 letter, Secretary Johnson added that “DHS’s ability to fully comply with
this unfunded mandate of 100 percent scanning, even in [the] long term, is highly improbable,
hugely expensive, and in our judgment, not the best use of taxpayer resources to meet this
country’s port security and homeland security needs.”85 The Secretary also stated that he had
instructed CBP to fulfill the underlying objective of 100% scanning by, among other things,
making refinements to its layered-security/risk-management strategy86
Container Security Initiative (CSI)
The Container Security Initiative (CSI) is a partnership program among CBP, Immigration and
Customs Enforcement, and law enforcement agencies in CSI countries. Under the program, CBP
officers and other federal agents at the National Targeting Center–Cargo (NTC-C) in Herndon,
VA, review advanced sea cargo data and identify high-risk containers. High-risk containers are
targeted for radiation detection and NII scanning within CSI ports. Host state law enforcement
agents typically conduct physical scans in the foreign ports, and CBP personnel located in the

82 CBP, Report to Congress on Integrated Scanning System Pilots (Security and Accountability for Every Port Act of
2006, Section 231
). Also see DHS, Congressional Budget Justification–CBP Salaries and Expenses, FY2013, p. 48.
83 Letter from Janet Napolitano, Secretary of Homeland Security, to Hon. Joseph I. Lieberman, Senator, May 2, 2012.
The 9/11 Act permits the Secretary to extend the deadline by two years and in additional two-year increments by
certifying that two of the following conditions exist: that scanning systems are not available, are insufficiently accurate,
cannot be installed, cannot be integrated with existing systems, will significantly impact trade and the flow of cargo,
and/or do not provide adequate notification of questionable or high-risk cargo. In her notification to Congress,
Secretary Napolitano certified that the use of systems to scan containers would have a significant and negative impact
on trade capacity and cargo flows, and that systems to scan containers cannot be purchased, deployed, or operated at
overseas ports due to limited physical infrastructure.

port or in the United States evaluate the scan results. When an abnormality is detected, host state
law enforcement agents conduct a physical inspection before the container is loaded on a U.S.-
bound ship. CBP officers and ICE agents participate in such inspections either remotely or as
partners within foreign ports.
According to CBP, the CSI is operational in 58 foreign seaports in 30 countries; approximately
80% of all U.S. incoming maritime containerized cargo originates in or transits through a CSI
port.87 About 1% of all cargo passing through CSI ports bound for the United States is scanned
using radiation detection technology and NII scanning prior to being shipped to the United States
(also see “100% Scanning Requirement”).88 CBP reported that in FY2013, CBP officers reviewed
11,228,203 bills of lading and conducted 103,999 examinations of high-risk cargo in cooperation
with host country counterparts.89
Import Processing At Ports of Entry
Imported goods are not legally entered until after the shipment has arrived within the port of
entry, entry of the merchandise has been authorized by CBP, and all estimated duties have been
paid.90 The importer of record (i.e., the owner, purchaser, or a licensed customs broker) has the
option to enter the goods for consumption, enter them into a bonded warehouse at the port of
entry, or to transport the cargo in-bond to another port of entry for processing.
If goods are being entered for consumption (e.g., going directly into U.S. commerce) importers
are typically required to file entry documents within 15 calendar days of a shipment arriving at a
U.S. port of entry. These documents may include an entry manifest or other form of merchandise
release, evidence of the right to make entry, commercial invoices, packing lists, and other
documents necessary to determine admissibility. Since most cargo is released electronically,
however, packing lists and invoices are rarely requested.
Importers also must provide evidence that a bond has been posted with CBP to cover estimated
duties, taxes, and charges that may accrue. If the goods are to be released from CBP custody, an
entry summary must be filed and estimated duties deposited at the port within 10 days of the
entry of the merchandise.
Based on screening of the cargo and a review of the entry documents, CBP officers at the port
make a preliminary determination about cargo admissibility and either release or challenge the
shipment. For cargo that is challenged, importers may be required to provide additional
documents or take other steps to prove admissibility.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Import Security and Trade Enforcement at U.S. Ports
Radiation Scanning
The SAFE Port Act91 requires that 100% of cargo containers passing through U.S. POEs be
scanned for radioactive material prior to being released from the port. Containers typically pass
through drive-through portals at about five miles per hour, and radiation detection requires a few
seconds per container, apart from congestion.92 Portals are often placed at natural choke-points,
including near port exits or entrances to facilitate 100% radiation scanning. A radiation alarm may
be triggered by naturally occurring radiation found in granite and other stone or by radioactive
medical or scientific materials. When radiation is detected, further tests are conducted, including
more sophisticated scanning or physical inspection, to match the radioactive profile detected
against known radioactive materials in the shipment, or to identify and remove illegal radioactive
material.
As of August 2012, CBP reported that 100% of containerized cargo entering through Northern
and Southwest border land ports and 99.8% of containerized sea cargo is scanned through
radiation portal monitors (RPMs).93 According to a 2012 GAO report, however, radiation
scanning of international rail cargo mainly is conducted with less powerful portable, hand-held
scanners; and scanning may only be triggered when NII scanning indicates a cause for alarm.94
Another GAO report found that CBP’s radiation portal monitors may not detect certain nuclear
materials when they are lightly shielded, and that such shielding may not be detected in the
absence of NII scanning.95 GAO also has identified problems with the acquisition of RPMs by
CBP and by DHS’s Domestic Nuclear Detection Office.96
Non-Intrusive Inspection (NII) and Secondary Inspections in U.S. Ports
Within each port, officers in CBP’s Advanced Targeting Unit use the ATS to select containers at a
high risk for weapons of mass destruction, drugs, or other contraband for NII scanning.
Containers with risk scores above a certain threshold are automatically selected for such scans,
and officers also may select additional containers for NII scanning and/or physical inspection.

Notes: Data include inspections of empty and full containers. Secondary inspection includes non-intrusive
imaging (NII) scanning and/or opening a cargo container for physical inspection.
As Table 1 indicates, the majority of cargo containers between FY2005 and FY2013 entered by
ship (about 101 million out of 220 million containers, or 46%) or by truck (about 95 million, or
44%), with the remainder entering by rail (about 24 million, or 11%). Secondary inspection rates
vary greatly by mode of entry, with 91% of all rail containers being scanned or inspected, versus
28% of truck-mounted containers, and 5% of maritime containers. Overall, about 25% of all
incoming containers (6.1 million out of 24.3 million) were subject to secondary inspection in
FY2011.
The different NII scanning percentages may reflect differences in port infrastructure and the
shipping process, among other factors. While land ports are naturally structured as choke points
with a relatively limited number of trucking or rail lanes, sea ports are larger facilities, and
containers from any given ship may flow in multiple directions before being placed on another
ship, rail, or truck conveyance. Truck and rail cargo also may be more regular than maritime
cargo (i.e., one type of good per container), whereas maritime containers may be more likely to
include multiple shipments bundled into a single container, making NII scanning more time
consuming. The flow of maritime shipping is also less regular than land-based modes. Whereas
truck and rail traffic arrives in a relatively steady stream at ports of entry, maritime cargo arrives
in surges, with each incoming ship containing hundreds or thousands of containers that must
quickly be processed.
Some Members have expressed frustration that most cargo is not scanned before entering the
United States, including the great majority of maritime cargo. However, while NII scans take less
than one minute per container overall, evaluating NII images and comparing them to declared
cargo manifests is a labor-intensive process that may involve multiple officers and may require up
to several minutes per container, depending on the complexity of the cargo. Thus, substantially
Congressional Research Service
25

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

increasing the proportion of cargo scanned likely would be resource-intensive, and could slow the
flow of goods in and out of the United States. Moreover, CBP estimates that the overwhelming
majority of cargo entries are lawful,97 so that increased scanning may be of limited practical
benefit (also see “100% Scanning Requirement”).
Trade Enforcement Inspections
CBP trade specialists at POEs also target certain containers for trade enforcement inspections
based on ATS risk scores along with other intelligence and local enforcement considerations.
Goods may be selected for trade enforcement examinations related to concerns about product
safety, intellectual property violations (copyright or trademark infringement), counterfeit goods,
labeling violations, or anti-dumping and countervailing duty (AD/CVD) circumvention, among
other considerations. Trade enforcement inspections ensure that goods are correctly classified and
accurately weighed for duty assessment, and administrative corrections are made as necessary.
Trade specialists also look for evidence of trade-related fraud (e.g., false rules of origin labeling
or valuation of merchandise), which may trigger an investigation by CBP trade specialists, ICE
investigators, or other federal agents.
CBP’s trade enforcement efforts are focused on five priority trade issues (PTIs), or “high risk
areas that can cause significant revenue loss, hurt the U.S. economy, or threaten the health and
safety of the American people.”98 The five issues are antidumping and countervailing duties;
import safety; intellectual property rights; textiles and apparel; and trade agreements.99 According
to CBP, these PTIs serve as the core of CBP’s trade enforcement strategy, and CBP focuses
considerable resources and personnel on them. CBP’s Performance and Accountability Report,
Fiscal Year 2013
reported gains in identifying “threats, challenges, and vulnerabilities in each
step” of the duty collection process, and in targeting textile and apparel manufacturers overseas
whose trade preference claims could not be substantiated.
Trade enforcement examinations can be a time-consuming procedure, especially in the case of
containers with diverse contents, because CBP officers must physically unpack the container and
examine all of its contents or a sample of contents. In some cases, such as when containers
include certain food, plant, or animal products, CBP officers may be required to bring in
representatives from other federal agencies (e.g., the U.S. Department of Agriculture) to assist
with physical inspections, and to determine whether or not a good may be admitted or how it
should be classified. Any storage and transportation costs associated with trade enforcement
examinations are borne by the importer, and may also occur outside the port at a centralized
examination station. As noted, one benefit of C-TPAT membership is that large shipments subject

97 CBP projected the trade compliance rate (measured against transactional discrepancies) to be 98.9% in FY2012, and
the compliance rate averaged 98.0% for FY2006-FY2012; see CBP, Import Trade Trends: FY2011 Year End Report,
Washington, DC 2012, p. 17. Similarly, CBP’s audit of travelers at ports of entry found that about 99% of travelers at
air and land ports in FY2006 were in compliance with all relevant rules, laws, and regulations; see GAO, Border
security: Despite Progress, Weaknesses in Traveler Inspections Exist at Our Nation’s Ports of Entry
, GAO-08-219,
November 2007, p. 47. And in FY2007-FY2010, CBP’s Office of Field Operations made a total of 168,504 drug
seizures at ports of entry—a figure which amounts to less than 0.2% of all cargo entries, and less than 0.01% of all
cargo and travelers entering through POEs; see DHS Office of Inspector General, CBP’s Efficacy of Controls Over
Drugs Seizures

to secondary inspection may be eligible for stratified exams, minimizing storage costs in these
cases (see “Text Box: CBP Trusted Trader Programs”).
As Table 2 indicates, about 2% (3.2 million out of 140.5 million) of all cargo containers seeking
admission to the United States were physically examined at a POE in FY2005-FY2013; and
slightly less than half (1.5 million out of 3.2 million) of physical examinations were trade-related
(as opposed to security-related). These examinations resulted in a total of 157,905 trade-related
seizures during this period, meaning that seizures occurred in about 10% of examined containers.
Most seizures were related to intellectual property violations (122,355 cases; 77% of trade-related
seizures) and import safety violations (24,503 cases; 16% of trade-related seizures).

Cargo Release
Cargo that is found to be admissible and cleared through security and trade enforcement
inspections is formally released into U.S. commerce. In these cases, importers must file additional
entry summary documentation within 10 days to provide detailed information about the shipment
(including customs classification, weight, and duty rates) that CBP will use to determine that all
import requirements have been satisfied.100 Importers must pay storage and transportation costs

100 In certain cases, including certain produce and other merchandise from Mexico and Canada, shipments consigned to
the U.S. government, and articles for a trade fair, shipments may be delivered immediately to the consignee, rather than
being held between formal entry and delivery as in the standard procedure described above. In these cases, importers
file entry documents and entry summary documents and pay estimated duties at the same time within 10 working days
of the cargo’s release.

during the cargo release period, and must pay initial customs duties and fees assessed prior to
taking possession of imported goods.
Trade Facilitation
Several CBP programs are in place that are designed to facilitate lawful trade during and after the
entry process, including CBP “Simplified Entry” process, its Centers of Excellence and Expertise
(CEE), and the in-bond transportation system.
Automated Commercial Environment (ACE) Cargo Release
(formerly “Simplified Entry”)

In April 2011, CBP established a joint industry-CBP working group to establish a simplified entry
process intended to reduce the administrative burden for importers, while providing the necessary
documentation needed by CBP officials to do their jobs of identifying risks and collecting tariffs,
taxes, and fees. The “Simplified Entry” process proposed to reduce the number of duplicative
data elements required to obtain release of products for cargo. The process allows filers to submit
a streamlined data submission of 12 required and 3 optional data elements. These data may be
filed early in the import process to allow an expanded window of opportunity to identify potential
risks. Filers may also update entry information throughout the import process to provide CBP
more accurate data.101
In December 2011, CPB began a simplified entry pilot program for air cargo. CBP selected 9
customs brokers (out of 40 applicants) operating out of 3 POEs (Chicago, Atlanta, and the
Indianapolis Express Consignment Operation). In August 2012, CBP opened the program to all
self-filers who hold a Tier-2 or higher C-TPAT status, and all importers who use customs brokers
to file simplified entry information.102 As of September 2013, over 159,000 simplified entries had
been filed for more than 1,100 importers.103
In November 2013, CBP re-named the program the “ACE Cargo Release Test,” and dropped the
C-TPAT requirement to allow more importers to participate. Eligible applicants are now accepted
on a first-come, first-served basis, but if the volume of applicants exceeds CBP’s administrative
capabilities, CBP reserves the right to select individual participants to ensure a diverse pool.104 In
February 2014, the test was expanded to cargo entries by ocean and rail; and to limited truck
entries at 10 POEs on May 2014.105

Centers of Excellence and Expertise
To facilitate post-entry processing, CBP has launched several Centers of Excellence and Expertise
(CEEs or Centers) since October 2011 to serve as industry-specific single points of post-entry
processing for certain businesses enrolled in the C-TPAT and ISA trusted trader programs.106 The
Centers are designed as “one-stop-shops” to align customs practices with the demands of modern
business and to facilitate trade in the targeted industries. CBP-integrated staff in the Centers
process entry summaries, post-entry amendment and correction reviews, protests, and other
administrative work.107
The 10 CEEs operating as of November 2012 are as follows:
• Electronics in Los Angeles;
• Pharmaceuticals, Health and Chemicals in New York;
• Automotive and Aerospace in Detroit;
• Petroleum, Natural Gas, and Minerals in Houston;
• Apparel, Footwear, and Textiles in San Francisco;
• Agriculture and Prepared Products in Miami;
• Consumer Products and Mass Merchandising in Atlanta;
• Industrial and Manufacturing Materials in Buffalo;
• Base Metals in Chicago; and
• Machinery in Laredo.108
The Centers were designed so that the industries would receive fewer cargo delays, reduce costs,
and enjoy greater predictability, while CBP would be able to shift its emphasis at the ports of
entry to address higher-risk shipments and focus on trade enforcement issues. On a similar track,
an Account Executive (AE) pilot was established to work with selected trusted partners in the
electronics industry. At the end of these pilots, the two concepts were combined. The Centers also
support improved information sharing between industry representatives and CBP staff to lead to
more focused trade enforcement efforts.109
In-bond Transportation
In-bond transportation facilitates the efficient flow of goods trade into the United States by
allowing imported merchandise to arrive at one U.S. POE and be transported by a bonded carrier
to another U.S. POE, where it officially enters into U.S. commerce (duties are paid upon entry), is

106 The first two CEEs began as pilot programs in November 2010 when CBP established an Information Technology
and Consumer Electronics CEE in Los Angeles and a Pharmaceuticals, Health and Chemicals CEE in New York. After
evaluation, these CEEs were established permanently in October 2011. On May 10, 2012, CBP announced the creation
of two additional Centers: Automotive and Aerospace in Detroit, and Petroleum, Natural Gas, and Minerals in Houston.

exported out of the United States (duty payment is not required), enters a bonded warehouse
(duties are paid upon release), or is brought into a free trade zone for further processing (duties
are paid on the finished product upon entry).110 According to CBP, the four field offices that
process the most in-bond shipments are Los Angeles, New York, Miami, and Seattle.
Many in the trade community value the flexibility provided by the in-bond system as a way to
avoid congestion and delays at U.S. seaports, but a 2007 GAO report raised concerns that CBP
collects little information on in-bond shipments, does not know exactly how often the system was
used, and performs limited analysis on in-bond flows.111 As a result, CBP is reportedly unable to
identify systemic risks that could lead to revenue losses or to implement appropriate compliance
measures to mitigate such risks.112 GAO also found that many in-bound cargo shipments
remained unreconciled, and that regulatory flexibility that benefited the trade community created
challenges for CBP’s efforts to track in-bond shipments.113 Some in the trade community have
also commented that vulnerabilities in the in-bond system may allow the entry of contraband
goods, such as illegal apparel shipments or goods that violate international property rights laws.114
On February 22, 2012, CPB proposed regulatory changes to the in-bond process. Among other
things, the proposed changes would require electronic filing of in-bond applications, that
applications contain 6-digit Harmonized Tariff Schedule (HTS) classification of all in-bond
merchandise, a 30-day maximum arrival time for all in-bond shipments (except for pipelines),
and the disclosure of any information relevant to the safety and security of the shipment.115 As of
this writing, CBP has not made any announcements regarding the adoption or implementation of
these proposed rules. A public comment by the National Customs Brokers and Forwarders
Association of America pointed out, among other things, that some of the information that CBP
proposed to require for in-bond shipments were duplicative, as they were already required
pursuant to the Importer Security Filing and other CBP regulations.116
Post-Entry: Continued Trade Enforcement
CBP responsibilities do not end when a product has entered the United States. Importers have up
to 180 days from the date of entry to challenge CBP’s assessment of duties owed, after which
CBP makes a final determination of the rate and amount of duty owed, a process known as

liquidation, and importers pay additional duties or receive refunds to reconcile any differences
between estimated and final duties owed.117 CBP trade specialists and other federal agencies
involved in trade enforcement may conduct additional enforcement activities in the period after
cargo enters the United States, including audits of importers’ records to ensure compliance with
U.S. trade laws.
Liquidation
Liquidation is “the final computation or ascertainment of duties on entries for consumption or
drawback entries.”118 In most cases, the liquidation must take place within one year of the
merchandise entry, but may be extended if (1) CBP does not have the documentation for proper
appraisement, classification, or to ensure compliance with trade laws; or (2) the importer requests
an extension and shows good cause. Liquidation also may be suspended (meaning the final
assessment of duties is held open) in certain cases, including cases in which merchandise is
affected by a pending court case, products are suspected to be prohibited, or merchandise has not
been completely withdrawn from a customs warehouse or otherwise accounted for.119
Liquidation is suspended, for example, if imported merchandise is the subject of an ongoing
antidumping (AD) or countervailing duty (CVD) investigation.120 In AD and CVD investigations,
the suspension of liquidation begins as soon as the ITA makes an affirmative preliminary
determination of dumping or subsidies. Suspensions end, and final duties are collected, after an
administrative review of the investigation is conducted. In a Government Accountability Office
(GAO) investigation regarding CBP’s collection of AD/CVD duties, GAO investigators noted
that the long lag time between cash deposit of estimated duties and the collection of the final
duties assessed (on average 3.3 years, and in many cases much longer) made it difficult for CBP
to collect the duties. In fact, the longer the lag time and larger the amount of duty owed, the
greater the likelihood that CBP would be unable to collect the duties owed.121
Recordkeeping and Post-Entry Audits
As a general rule, CBP requires that all records regarding imports of merchandise be kept for a
period of five years after the date of entry.122 These documents must be made available to CBP

117 See 19 C.F.R. §174, 19 U.S.C. 1514 (c)(3) as amended.
118 19 C.F.R. §159.1.
119 19 C.F.R. §§159.52-159.57.
120 AD and CVD laws authorize the imposition of duties if (1) the International Trade Administration of the
Department of Commerce (ITA) determines that foreign merchandise is being, or likely to be, sold in the United States
at less than fair value or a foreign country or public entity has subsidized the merchandise; and (2) the U.S.
International Trade Commission (USITC) determines that an industry in the United States is materially injured or
threatened with material injury, or that the establishment of an industry is materially retarded, due to imports of that
merchandise. For a fuller discussion of AD and CVD issues, see CRS Report RL32371, Trade Remedies: A Primer, by

officials if they request an audit to determine if any additional duties, fees, and taxes are owed, or
to insure that the importer is in compliance with laws administered by CBP.123
Regulatory Audits
CBP conducts two main types of regulatory audits.124 First, focused assessment (FA) audits are
risk-based evaluations of a company’s CBP transactions. FAs begin with an assessment of the
company’s internal controls in order to identify system strengths and weaknesses and help predict
future compliance. If certain risk areas are identified, CBP auditors examine those areas. Second,
quick response audits (QRAs) are single-issue audits narrowly focused to address a specific
objective within a short period of time. Examples of QRAs could include an audit of an
importer’s operations to determine if unlawful transshipments may have occurred, or an audit of a
company’s internal controls on intellectual property rights.125 Both types of audits may result in
enforcement action and penalties if discrepancies are found.
Prior Disclosure
Any party who may have violated U.S. trade laws (including undervaluation, inaccurate
description of merchandise, AD/CVD duty evasion, or improper country of origin declarations or
markings) may choose to make a prior disclosure of the violation and thereby become eligible for
reduced penalties.126 In order to receive reduced penalties, the party must make a complete
disclosure before, or without knowledge of, a formal CBP investigation.127
Issues for Congress
Reauthorization of CBP’s trade, enforcement, and security functions has been the subject of
several hearings and legislative proposals in recent years. This section reviews selected issues
addressed in previous legislation and hearings related to import policy involving customs issues,

import security, along with customs modernization and interagency coordination. Many of these

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Trade Facilitation
Some in Congress have identified trade facilitation as a top priority with respect to U.S. customs
law and CBP’s import policies.128 Recent legislative attention has focused on the possible
authorization of existing CBP trade facilitation programs, on trusted trader program benefits, and
on proposals to reduce wait times at ports-of-entry, including through increases in CBP port-of-
entry staffing.
Authorization of Existing CBP Trade Facilitation Programs
Several CBP trade facilitation efforts have been initiated as pilot programs without explicit
legislative authorization. Examples include the Simplified Entry program (see “Automated
Commercial Environment (ACE) Cargo Release (formerly “Simplified Entry”), and the Centers
of Excellence and Expertise (see “Centers of Excellence and Expertise”). In February 2014, the
test was expanded to cargo entries by ocean and rail; and to limited truck entries at 10 POEs in
May 2014.
S. 1269 as reported on May 13, 2015 by the Senate Finance Committee and S. 1907, as ordered
reported by the House Ways and Means Committee on April 23, 2015, seek among other things,
to direct CBP to improve the benefits received by trusted trader program participants, and to
authorize the Centers of Excellence and Expertise.
Trusted Trader Program Benefits
CBP’s risk management approach to import policy emphasizes the use of trusted trader programs,
such as C-TPAT and FAST, in part, to identify and facilitate the entry of low-risk importers and
cargo, while focusing enforcement efforts on higher-risk flows. For this reason, some in Congress
and some CBP officials support maximizing participation in C-TPAT and related programs.
However, some businesses have described the benefits received by C-TPAT members as
inadequate, especially in light of the time and financial investments required to become certified
as C-TPAT members. In congressional testimony, some industry representatives have described
their constituents as “particularly unsatisfied” by CBP’s “one-size-fits-all approach” to risk
management.129 And while it appears that many large import-related businesses have joined
C-TPAT, CRS estimates, based on CBP data that only about 6% of all import-related businesses
and about 8% of customs brokers have joined the program.130

according to data provided by CBP Office of Legislative Affairs, August 24, 2012. By comparison, U.S. Census data
indicates that there were 181,648 U.S. importers in 2010 and CBP data indicate that there were 11,000 customs
brokers; see U.S. Census, “A Profile of U.S. Importing and Exporting Companies, 2009-2010,” http://www.census.gov/

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

One issue for Congress is whether to increase C-TPAT benefits or initiate other steps to
strengthen trusted trader programs in an effort to increase C-TPAT participation and to facilitate
trade flows.131
In practice, however, it may be difficult to substantially expand C-TPAT benefits. In the case of
land ports, the primary benefit of C-TPAT/FAST membership is access to dedicated lanes where
wait times may be shorter and more predictable. However, CBP may have limited capacity to add
lanes because many ports are located in urban areas with limited space for expansion.132 And even
if new lanes can be added at the border, carriers may confront ingress and egress bottlenecks that
limit the benefits of such investments. In the case of maritime imports, the primary benefit of C-
TPAT membership is that low ATS scores reduce the likelihood of an inspection. But with just 4%
of all maritime containers selected for secondary inspection (see Table 2), C-TPAT membership
may offer little practical advantage in this regard. In addition, some CBP officials have told CRS
that further reductions in C-TPAT inspections may raise security risks because smugglers may
establish clean companies and join the program in order to game the system.133 For these reasons,
the best way to encourage C-TPAT membership may be to increase enforcement against non-
members, thereby increasing the relative benefits of C-TPAT membership.
Wait Times at Land Ports of Entry
Some in Congress have expressed concern about delays and unpredictable wait times at land ports
of entry, particularly on the U.S.-Mexico border.134 Several governmental and nongovernmental
groups have examined this issue and recommended strategies for reducing wait times. A draft
Commerce Department report, for example, identifies three main strategies: (1) optimizing the
dispersal of demand across available capacity; (2) improving throughput within the existing
system through trusted trader programs and risk-management; and expanding capacity by adding
crossing lanes (physical infrastructure); and (3) increasing staffing and operating hours.135
Similarly, a Department of Homeland Security Southwest Border Task Force made 10
recommendations in 2009 for improving U.S.-Mexico commerce, including enhanced trusted
trader programs and risk management systems, faster throughput through improved scanning
systems and document reviews, expanded POE infrastructure, and additional POE officers.136 A

(...continued)
indicate that C-TPAT members account for 50-56% of all imports by value.
131 Certain C-TPAT benefits are described in statute under §§213-216 of the SAFE Port Act of 2006. During the 112th
Congress, the SAFE Port Act Reauthorization Act (S. 832, introduced April 14, 2011) and the Securing Maritime
Activities through Risk-Based Targeting (SMART) Port Security Act (H.R. 4251, passed House, June 28, 2012), for
example, would have directed CBP to provide additional incentives to joining C-TPAT by promoting an information
sharing program with certain C-TPAT members regarding potential supply chain vulnerabilities.

third set of taskforce recommendations presented in 2011 included a recommendation that CBP
take the lead on adopting best practices related to border inspections, including use of automated
risk management, establishing an automated release process, and developing a “single window”
approach so that all importers and customs brokers to provide all of the necessary data elements
at one U.S. government portal.137
While many strategies for promoting faster throughput may be in tension with security and trade
enforcement goals (i.e., because faster throughput means less time reviewing each case),
increasing port of entry personnel levels may speed flows while also increasing enforcement
capacity. Moreover, as Figure 2 illustrates, while staffing for enforcement between ports of entry
(i.e., U.S. Border Patrol) more than doubled between FY2004 and FY2012 (increasing from
10,819 to 21,394), DHS’s Office of Field Operations (OFO) staffing at ports of entry increased
just 20% during this period (from 18,110 to 21,790), even as enforcement responsibilities
increased substantially in the post-9/11 period.

use of technology and risk management (i.e., trusted trader programs), among other strategies, to
reduce border wait times.139
Trade Enforcement
CBP’s role in trade enforcement has been the subject of congressional attention, especially as it
relates to CBP’s collection of tariffs and fees and its enforcement of trade laws including
antidumping (AD) and countervailing (CVD) duty orders, U.S. intellectual property (IPR) laws,
textile and apparel trade violations (e.g., transshipment), and import safety regulations. Some in
Congress and some U.S. businesses assert that CBP does not adequately enforce these laws. Some
manufacturers also allege that CBP has not adequately investigated allegations of duty evasion,
product mislabeling, fraudulent country of origin declarations, or deliberate misclassification of
shipments.140 And some assert that their intellectual property rights have been violated by
growing imports of counterfeit goods, and that CBP collaboration with the private sector to
identify and enforce IPR violations has been inadequate.141 Manufacturers also have asserted that
CBP has not actively investigated alleged violations. CBP officials have responded that although
CBP would like to be as transparent as possible, the agency must also honor due process
requirements, which may require confidentiality.142
Import Security
The major policy question with respect to import security is how CBP can minimize the risk that
chemical, biological, radiological, and nuclear (CBRN) weapons, illegal drugs, and other
contraband will enter through U.S. POEs, while also limiting the costs and delays associated with
such enforcement.143
100% Scanning Requirement
The SAFE Port Act of 2006 (P.L. 109-347), as amended, required that as of July 1, 2012, that
100% of maritime cargo containers admitted into the United States be scanned through non-
intrusive inspection (NII) and radiation detection equipment in a foreign port prior to being
loaded on a U.S.-bound ship, unless the Secretary of DHS extends this deadline.144 On May 2,

2012, then-Homeland Security Secretary Napolitano notified Congress that she would exercise
her authority to extend the 100% scanning deadline.145 In May 2014, Homeland Security
Secretary Jeh Johnson extended the Department’s time to meet the requirement by an additional
two years.146With just 1% of cargo scanned before being loaded on U.S.-bound ships—and only
about 5% of cargo subject to NII scanning at any point (see Table 1)—some Members have
expressed frustration that DHS has made little progress toward implementing 100% scanning, and
questioned the department about plans to increase the percentage of cargo scanned.147
The decision to delay implementation of the 100% scanning program partly reflects the
department’s findings from the Secure Freight Initiative (SFI) 100% scanning pilot program. In
its final report to Congress on the program, CBP identified three main obstacles to implementing
100% scanning at all foreign ports.148 First, 100% scanning requires significant host state and
private sector cooperation, but some foreign governments and business groups do not fully
support 100% scanning. Second, 100% scanning would be logistically difficult. Initial pilots were
deployed in relatively low-volume ports with natural chokepoints, but many cargo containers pass
through large volume ports with more varied port architectures. Logistical challenges are
particularly burdensome given the priority that the modern shipping industry places on the rapid
and efficient movement of goods. Third, 100% scanning would be costly. In February 2012, the
Congressional Budget Office (CBO) estimated that implementing 100% scanning at foreign ports
would cost an average of $8 million per shipping lane, or a total of $16.8 billion to implement
100% scanning for all U.S.-bound containers.149 Port operators and foreign partners also absorb
costs associated with fuel and utilities, staffing, and related expenses.
100% Scanning Versus Risk-Based Scanning
In light of these challenges, Congress may consider provisions to allow DHS to scan less than
100% of U.S.-bound cargo. Two reasons to scan less than 100% of incoming cargo are to reduce

In her notification to Congress, Secretary Napolitano cites “diplomatic, financial, and logistical” obstacles to
implementing a 100% scanning system. Pursuant to §232(b)(4) of the SAFE Port Act, as amended, Secretary
Napolitano identified two conditions which necessitated the deadline extension: that the use of systems to scan
containers would have significant and negative impact on trade capacity and cargo flows, and that systems to scan
containers cannot be purchased, deployed, or operated at overseas ports due to limited physical infrastructure.

the costs of enforcement and to speed processing time. Some assert that the costs of 100%
scanning may be great enough to shift certain trade flows away from U.S. markets, potentially
harming the U.S. economy.
More generally, 100% scanning conflicts with DHS’s general approach to risk management,
which seeks to focus scarce inspection resources on the highest-risk containers.150 By scanning a
smaller number of containers, DHS may be able to devote additional resources to each individual
scan. This consideration is important because NII is labor-intensive, and scanning fewer
containers may allow DHS to subject individual scans to greater scrutiny, and to maintain a lower
threshold for opening containers with questionable NII images.
If illicit cargo is estimated to be limited to less than 1% of incoming containers, as CBP believes
to be the case, focusing enforcement on the likeliest containers may be the most effective
enforcement strategy. According to this line of thinking, rather than focus on 100% scanning,
people concerned about import security may emphasize risk-based scanning along with
investment in CBP intelligence to improve targeting, and/or increased CBP personnel, which
would allow ports to conduct a larger number of targeted special enforcement operations.151
Scanning Abroad Versus Scanning in U.S. POEs
If Congress were to revisit the 100% scanning requirement, a second question may be where
security scanning takes place. While the SAFE Port Act, as amended, requires cargo containers to
be scanned in foreign ports, most NII scanning now occurs within U.S. ports, where CBP and
DHS grant programs have supported investments in scanning equipment, and where Congress has
direct authority to impose scanning requirements. Efforts to implement 100% scanning abroad
may be difficult for the reasons discussed above.
With respect to radiation scanning to defend against a WMD attack, however, scanning cargo
within U.S. ports may come too late in the process to prevent an attack—that is, the threat that a
nuclear weapon or dirty bomb would be detonated within a port prior to being scanned. Given
that several major ports are located close to population centers, and given the costs that would be
associated with a significant disruption in port activities, a case can be made for conducting
radiation detection scanning in foreign ports, before cargo is shipped to the United States.152
Scanning within foreign ports may be a less urgent priority with respect to NII scanning to detect
drugs and other contraband. In this case, detection at any point prior to cargo being released from
a U.S. POE may still accomplish the enforcement goals of detection and interdiction.

150 See CBP, “CBP Trade Strategy: Fiscal Years 2009-2013,” Washington, DC: 2009.
151 Under a purely risk-based scanning system, DHS would scan only those containers identified as high risk. Although
such a system may offer the greatest cost savings and efficiency (i.e., would offer the greatest reduction in the number
of scans conducted), it also would be vulnerable to smugglers who study the scanning protocols or otherwise learn
about DHS’s risk modeling and intentionally adopt “low risk” profiles in order to avoid being scanned. Thus, any risk-
based scanning system may also require some amount of random scanning.

Transportation Worker Identity Credential (TWIC) Card Readers
Some Members have expressed frustration that DHS has not yet published final regulations
governing card readers for the Transportation Worker Identity Credential (TWIC) program.153
One issue for Congress is whether to encourage DHS through legislation to move ahead more
quickly with regulations to require that ports use TWIC card readers to restrict access to secure
areas.154
Yet Congress may also want to consider the overall effectiveness of the TWIC program. In 2011,
a GAO report identified several weaknesses with the TWIC program, including that internal
controls in the enrollment process and background checks may not limit cards to eligible
individuals or insure that they maintain their eligibility after cards are issued, that facilities were
vulnerable to security breaches in GAO’s covert testing, and that DHS has not adequately
assessed TWIC program effectiveness.155 DHS’s report on its TWIC pilot program also identified
strengths and weaknesses of the program, which may have contributed to the delay in publishing
regulations. On one hand, DHS found that TWIC readers functioned properly when installed and
operated in a manner that was consistent with a port’s operational needs, and that certain TWIC
readers verified card-holders’ credentials more efficiently than visual inspections by security
personnel. On the other hand, DHS also identified a number of problems that limited the overall
success of the pilot programs. In particular, some card readers were less efficient than visual
inspections; TWIC systems required more training than anticipated; some cards and card readers
malfunctioned; some facilities had problems installing TWIC readers; some readers had problems
scanning cards under certain environmental conditions; and some operators did not use the TWIC
readers correctly or consistently.156 In 2012-2013, GAO conducted a performance audit that
identified that many of the same weaknesses cited above persisted. GAO recommended, among
other things, that Congress should halt DHS’s efforts to promulgate a final regulation until the
successful completion security assessment of the effectiveness of using TWIC.157
Customs Modernization
Customs modernization refers to the transition from CBP’s Automated Commercial System
(ACS) to its Automated Commercial Environment (ACE) for managing trade-related data (see
“Pre-Entry: Advanced Cargo Screening, Scanning, and Inspections”), and the development of the
International Trade Data System (ITDS).158 This transition has taken longer than expected and has

2008 and May 2011, and published a final report on the TWIC card reader pilot program in August 2012.
154 In June 2012, for example, during the 112th session of Congress, the House passed the SMART Port Security Act
(H.R. 4251), which would direct DHS to publish a final regulation for the installation of TWIC readers.

substantially exceeded its original cost predictions,159 and not all import-related businesses have
established ACE accounts.160 Some Members of Congress and some business groups have
expressed frustration that ACE development lags behind expectations,161 however, CBP officials
report that most have expressed support for the plans that CBP has put forth to develop the
remaining core ACE processes in three years.162
In February 2014, the President issued Executive Order 13659, “Streamlining the Export Import
Process for America’s Businesses.”163 The Executive Order required the completion of the
International Trade Data System (ITDS), and automated “single window” through which
importers and exporters will be able to transmit data and coordinate with Federal trade-
participating government agencies (PGAs)164 regarding shipments of merchandise in an “efficient
and cost-effective” manner. The order mandated that by December 31, 2016: (1) PGAs would
have “capabilities, agreements, and other requirements” in place to utilize the ITDS; and (2) that
the Department of Homeland Security (DHS) would confirm the completion of operational
capabilities to enable trade community users to transmit import and export data to PGAs to
facilitate the release and clearance of goods, and to transition from paper-based to electronic
submission of data.165
CBP has designated ACE as the automated system that will become the platform for the “single
window” required by the Executive Order, and plans to integrate or disable all other electronic
functions by the end of December 2016.166 To that end, CBP has announced to the trade
community three key “mandatory use” dates in the development process:

(...continued)
2006.
159 The U.S. Customs Service initiated the transition to ACE in 1994, and initially estimated that implementation of the
new system would cost $150 million over a 10-year period. Five years later, in 1999, the GAO reported that that the
life-cycle cost had grown to $1.05 billion, over a 15-year life cycle; see General Accounting Office, Customs Service
Modernization: Actions Initiated to Correct ACE Management and Technical Weaknesses
, GAO/T-AIMD-99-186,
May 13, 1999, pp. 1-2. According to CBP’s Office of Legislative Affairs, Congress appropriated $3.2 billion between
2001 and May 2012 for the development of ACE.
160 According to CBP’s Office of Legislative Affairs, 20,600 ACE accounts have been established as of August 2012.
By comparison, there were 181,648 U.S. importers in 2010 and 11,000 customs brokers; see U.S. Census Bureau, “A
Profile of U.S. Importing and Exporting Companies, 2009-2010,” http://www.census.gov/foreign-trade/Press-Release/
edb/2010/edbrel.pdf; and CBP, “Becoming a Customs Broker,” http://www.cbp.gov/xp/cgov/trade/trade_programs/
broker/brokers.xml. Thus, CRS calculates that about 11% of eligible import-related business had established ACE
accounts. This calculation excludes freight carriers, so the actual percentage of eligible ACE account holders may be
somewhat less than 11%. On the other hand, as with C-TPAT membership, it appears that most large-scale importers
have established ACE accounts, as two-thirds of all customs duties and fees are collected through ACE.

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

• By May 1, 2015, all import or export manifest data filed electronically must be sent
through ACE. This requirement extends to all modes of transportation—air, rail, ocean,
and truck.
• By November 1, 2015, all electronic cargo release and entry summary data must be
transmitted to ACE, including any data that extends to the jurisdiction of PGAs.
• By October 1, 2016, all additional cargo data must be sent to ACE, including protest and
liquidation data.167
CBP has initiated ACE as a series of modules that encompass discrete phases of the import
process. In general, as new ACE modules are introduced, importers initially are permitted to use
either ACS or ACE for the affected task; and once the new ACE component has been tested and
proven effective, importers are required to use the ACE components as certain ACS functions are
disabled. The ACE development deployment schedule (latest version, December 2014) is
available on the CBP website.168
The ACE “Monthly Trade Update” for December 2014 provides a wrap-up of ACE deployment
efforts in 2014.169 The final phase of “Deployment D,” completed on January 3, 2015, included
the ability to file air import manifests (import manifests can now be filed for all modes of travel);
the ability to file and process single transaction and continuous bonds; and integration of
capabilities to support the Animal and Plant Health Inspection Service (APHIS), the Drug
Enforcement Agency (DEA), and the Office of Foreign Assets Control (OFAC).170
According to CBP, the Automated Commercial Environment system is on target to be completed
by the end of calendar year 2016.171 The agency’s FY2014 and FY2015 budget for the project
amounted to about $141 million each year, and CBP’s FY2016 budget request is $154 million.172
With respect to maintenance costs, CBP projects a per annum budget of $68 million between
FY2018–FY2026.173
S. 1269 and H.R. 1907 would address ACE by
• authorizing the ACE computer system;
• authorizing funding of $153.7 million from FY2016 through FY2018 to complete
ACE development and implementation;
• requiring several reports from CBP at various stages of ACE development and
implementation; and

complete ACE development, establishment, and implementation.
Interagency Coordination
CBP works with 47 partner government agencies (PGAs) that play a role in trade enforcement,
but CBP and its PGAs have different missions and do not always collaborate successfully to
implement U.S. import policies. For example, with respect to import security, important partners
include the Transportation Security Administration (TSA), which takes the lead on air cargo
scanning and TWIC cards, and the Coast Guard, which also plays a role on security and TWIC
card enforcement. With respect to trade enforcement, CBP officers rely on the Food and Drug
Administration and the Departments of Agriculture and Commerce, in certain cases, to identify
health and safety violations, or to rule on other complex import questions. Similarly, while CBP
conducts border enforcement of intellectual property rights at the port of entry, CBP relies on
partnerships with ICE and other federal agencies to conduct criminal investigations and prosecute
intellectual property theft and other trade violations. In this case, CBP’s primary mission to detect
and prevent illegal entries may conflict, to some degree, with ICE and other agencies’ efforts to
gather evidence and build cases against suspected trade violators. A DHS Office of the Inspector
General report in 2012 found that CBP and ICE do not always share information and intelligence
related to investigations, and that their data systems are not designed to allow efficient
information sharing.174
CBP and its partner agencies are attempting to advance interagency cooperation, in part, through
the Border Interagency Executive Council (BIEC), created in January 2010. The BIEC is
comprised of agency leaders at the Assistant Administrator and Assistant Commissioner level and
serves as an advisory board on interagency import safety issues. The BIEC also works in
collaboration with CBP’s Advisory Committee on Commercial Operations (COAC), the
International Trade Data System (ITDS), and the National Strategy for Global Supply Chain
Security.175
The ITDS, which is being implemented through ACE, is one tool for improving interagency
coordination. ITDS is an intergovernmental project to coordinate and standardize the collection of
trade enforcement data by all relevant federal government. The goal is to build a “single window”
for the electronic collection and distribution of standard government-wide import and export data
for the use of government agencies with a role in trade enforcement. Under Section 405 of the
SAFE Port Act, all federal agencies that require documentation related to the importation or
exportation of cargo are required to participate in the ACE once ITDS is fully operational. As of
this writing, all 47 PGAs are involved in ITDS implementation, with the Treasury Department
coordinating interagency participation and CBP responsible for building and managing ITDS.176

U.S. Customs and Border Protection: Trade Facilitation, Enforcement, and Security

Some in Congress may favor efforts to require other agencies to work more closely with CBP at
various stages of the trade enforcement process. One option might be to require that each agency
with responsibility for cargo clearance use the ITDS exclusively for authorizing the
documentation, clearing, or licensing of cargo. On the other hand, some Members may be
reluctant to delegate additional enforcement powers to CBP because doing so may dilute the
enforcement authority of other federal agencies, potentially undermining their own missions.
S. 1269 and H.R. 1907 would amend the Tariff Act of 1930 by adding a paragraph on information
technology infrastructure that would require the Secretary of the Treasury to work with the head
of each agency participating in the ITDS and the Interagency Steering Committee to ensure that
each agency
• develops and maintains the necessary information technology infrastructure to
support ITDS operation and submit all data electronically through ITDS;
• enters into a memorandum of understanding, or take other actions as necessary,
to provide for information sharing between the agency and CBP for ITDS
operation and maintenance; and
• identifies and transmits to the Commissioner of Customs the admissibility criteria
and data elements necessary to authorize the release of cargo by CBP so that CBP
can incorporate them into the operational functionality of ACE.
Concluding Comments
An overarching goal of U.S. trade policy is to facilitate the efficient flow of goods in and out of
the United States, but there is an inherent tension between the commercial interest in trade
facilitation and the often competing goals of enforcing trade laws and import security measures.
The Mod Act of 1993 (Title VI of P.L. 103-182) sought to address this tension, to a degree, by
replacing the previous model of trade enforcement, in which the then-U.S. Customs Service
(USCS) was responsible for the classification of goods and assessment of duties, with a “shared
responsibility” approach, in which importers make their own duty determinations and the customs
agency is primarily responsible for revenue collection and oversight of importers. In theory,
robust post-entry audits and high penalties for noncompliance should act as a deterrent, and
shared responsibility may facilitate legal flows without compromising trade enforcement.
The tension is more profound when it comes to import security, however, because post-entry
enforcement may be too late to prevent a significant security breach. Post-entry enforcement also
may be problematic for certain trade issues, such as consumer safety laws, and in AD/CVD cases
where harm may be done to U.S. industries. Thus, while C-TPAT follows a similar logic as the
Mod Act by “outsourcing” certain security functions from CBP to trusted industry partners, post-
9/11 security concerns may limit the benefits that may be offered to trusted traders—a fact that
has been a source of frustration to importers who play by the rules but still confront burdensome
trade procedures.
At the same time, certain programs may strengthen the overall import process without forcing
such facilitation-versus-enforcement dynamics. Transition to the Automated Commercial
Environment (ACE), for example, should streamline the import process while also enhancing
enforcement efforts through the International Trade Data System (ITDS). Similarly, improving

POE infrastructure and expanding POE personnel may speed trade flows while also making more
resources available for inspections. Yet these types of win-win programs often are expensive to
implement, and Congress may be reluctant to make such investments at this time.
