U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Summary
The National Association of Foreign Trade Zones (NAFTZ) has developed the Trade Agreement
Parity (TAP) proposal, introduced as H.R. 6415 (Pascrell in the 110th Congress) to address what
NAFTZ claims as the “unintended consequences” of free trade agreements. These are that free
trade agreements (FTAs), in granting tariff advantages to businesses that import components or
products from FTA countries, put companies that import components from third countries (not a
party to an FTA) at a tariff disadvantage. Critics, however, say the effects the bill generally sought
to address are the exact intended consequences of FTAs: the United States extends preferential
tariff treatment to components from an FTA partner country in exchange for that country’s
lowering of its tariff rates on U.S. products.
The TAP proposal would permit certain businesses to permanently “borrow” U.S. free trade
agreements (FTAs) in order to import components at rates below those they would normally be
charged under U.S. tariff law. There would be two stipulations: (1) the products using third-
country components would have to be produced in a U.S. foreign-trade zone; and (2) the product
would have to meet the rules-of-origin (domestic content) requirements of any FTA—which
could be satisfied by using entirely third country parts and U.S. labor, without input from any
other FTA partner country.
The TAP proposal is reportedly being widely promoted on Capitol Hill by its association sponsor,
the NAFTZ, as a tool for helping multinational corporations sourcing from non-FTA countries
“level the playing field” to achieve tariff parity with manufacturers sourcing from U.S. FTA
countries. In addition, it has been the subject of an editorial in the Wall Street Journal and the
subject of two economic studies: a staff study by the U.S. International Trade Commission
(USITC); and a study prepared for the NAFTZ by economists Dean A. DeRosa and Gary C.
Hufbauer.
Major policy implications of extending FTA-related benefits to goods from non-FTA countries
include impacts on U.S. parts producers, customs revenue collections, and trade and diplomatic
relations with FTA partner countries; the potential for the FTZ Board to be swamped with new
applications for FTZ status, and to be under increased political pressure to grant such status; a
debatable assertion by its association sponsor that it would create new U.S. jobs; and its impact
on the ability of the U.S. Trade Representative (USTR) to negotiate future FTAs.
The primary beneficiaries of TAP appear, from the analysis that follows, to be foreign
multinational corporations (especially motor vehicle producers) that source components from
non-FTA countries (i.e., China, Japan and the European Union), and some oil companies that
operate U.S. refineries. Potential losers could include parts producers in the United States and
FTA countries and U.S.-owned motor vehicle producers that source components from Mexico and
Canada.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Introduction
The National Association of Foreign Trade Zones (NAFTZ) developed the Trade Agreement
Parity (TAP) proposal, introduced as H.R. 6415 (110th Congress) by Representative William
Pascrell,1 to address claimed “unintended consequences” of free trade agreements.2 These are that
free trade agreements (FTAs), in granting tariff advantages to businesses that import components
or products from FTA countries, put companies that import components from third countries (not
a party to an FTA) at a tariff disadvantage. To remedy this “problem,” TAP would “level the tariff
playing field” by permitting companies operating in foreign-trade zones (FTZs) to “borrow”
permanently3 U.S. free trade agreements (FTAs) for their own use, to reduce or eliminate tariffs
on components from third countries.
Critics of the TAP proposal view the “unintended consequences” TAP seeks to address as exactly
the intended consequences of FTAs. The United States agrees to preferential duty treatment on
components coming from an FTA partner country in exchange for that country’s lowering its duty
rates on U.S. products. The effect of the TAP proposal would be to provide FTA-related
preferential duty treatment to components from third countries that have not signed FTAs with the
United States and have not made compensating reductions in their own duty rates on U.S.
products.
Under the TAP proposal, companies with U.S. manufacturing facilities could apply to the U.S.
Foreign Trade Zones (FTZ) Board for manufacturing authority. With FTZ manufacturing
authority, such corporations would then be entitled to reduce or eliminate tariffs on imported
components under the rules of origin and tariff provisions of any free trade agreement.4 This
means that so long as the product meets the rules of origin (U.S. domestic content or value added
and/or substantial transformation) requirements of any FTA, the tariff benefits of that FTA would
apply. The rules of origin requirement can be satisfied by using any combination of U.S. and/or
third country parts and labor exclusively. No parts, labor or input of any kind would need to come
from any FTA country.
U.S. foreign-trade zones and subzones are physical areas geographically located in the United
States but considered to be outside of U.S. customs territory for purposes of the tariff laws and
customs entry procedures.
Subzones are special-purpose zones established as an adjunct to a zone project for a limited
purpose (for example, a stand-alone manufacturing facility).
FTZs and subzones provide special customs procedures to U.S.-located facilities using foreign
inputs, which consist of FTA-country inputs and/or third country inputs. For items that are
processed in FTZs and then exported, no duties are payable. If, instead, the processed items are

1 The Pascrell bill did not mention the words “trade agreement parity,” although its provisions were substantively
identical to those in the NAFTZ proposal. H.R. 6415 would have “provide[d] that goods that are manufactured in a
foreign trade zone and comply with the rules of origin under a trade agreement to which the United States is a party
may enter the customs territory of the United States at the rate of duty applicable under that agreement.

then imported into the United States, no duties are payable on the foreign inputs until the goods
leave the zone. At the time the merchandise leaves the zone for sale in the United States (i.e., is
“entered for consumption”), the duty may be paid either on the condition of the merchandise as it
leaves the zone (with authority from the FTZ Board), or on its condition as it was first brought
into the zone.
FTZs help offset customs advantages available to businesses which produce goods offshore and
then import them into the United States for consumption duty-free under FTAs or preferential
tariff programs such as the Generalized System of Preferences (GSP), the Caribbean Basin
Economic Recovery Act (CBERA), the Andean Trade Preference Act (ATPA), and the African
Growth and Opportunity Act (AGOA).
In recent years, growth in FTZ activity has continued. While average zone savings per facility
may be lower, the contributory effect from the use of zone procedures on a U.S. plant’s overall
cost reduction efforts may be more significant than in the past. While the contributory effect will
vary by industry, the savings from the use of zone procedures may have an impact on whether the
production costs at a U.S. facility are competitive with a plant abroad. Many companies maintain
manufacturing facilities throughout the world and are able to shift production among plants. Any
action taken by the U.S. facility to reduce its costs can have an impact on the maintenance of the
activity and associated employment in the United States.
Why is This Proposal of Interest to Congress?
The TAP proposal is of interest to Congress for a number of reasons. It reportedly is being widely
publicized and promoted on Capitol Hill by its association sponsor, the NAFTZ as a tool for
increasing competitiveness and economic development. It is reflected in legislation that has been
introduced in Congress (H.R. 6415 in the 110th Congress). It has been the subject of an editorial
in the Wall Street Journal.5 In addition, two economic studies have been undertaken on it. One is
a staff study by the U.S. International Trade Commission (USITC). The other is a study prepared
for the NAFTZ by economists Dean A. DeRosa and Gary C. Hufbauer.6
Economic, Policy, and Administrative Implications
The TAP proposal is a complex issue, with potential economic, policy, and administrative issues
and implications. Economic issues, if Congress were to approve TAP, would include (1) the effect
of TAP on U.S. parts producers; and (2) the effect on Customs duties collectable.
A major trade policy consideration is that U.S. FTA partners agreed to preferential duty treatment
for components coming from the FTA partner country in exchange for that country’s lowering its
duty rates on U.S. products. The effect of the TAP proposal would be to provide FTA-related
preferential duty treatment to components from third countries that have not signed FTAs with the
United States and have not made compensating reductions in their own duty rates on U.S.
products. Identified trade policy issues include (1) the tariff benefit given operations that would

ordinarily be required to pay tariffs on imports; (2) the extension of FTA benefits to non-FTA
countries; (3) the impact of TAP on trade and diplomatic relations with FTA partner countries; (4)
the creation of a new trade preference program through TAP; and (5) the impact of TAP on the
USTR’s ability to negotiate future FTAs.
The TAP proposal may have implications for the USFTZ Board, made up of designees of the
Secretaries of Commerce and Treasury, an Executive Director, and a staff of seven professionals.
The USFTZ Board would be the gatekeeper charged with ensuring on a case-by-case basis, after a
lengthy process, that granting FTZ status for TAP purposes would not be “detrimental to the
public interest.”
Possible issues include (1) the potential that a flood of new applications by businesses for FTZ
status could swamp the U.S. Foreign-Trade Zones Board, necessitating a substantial increase in
administrative resources to handle the increased requests for FTZ status; (2) the FTZ Board staff
would take on the new burden of determining whether or not processing activities in subzones
would meet the rules of origin requirements of an FTA and whether duty-free treatment for
articles meeting the requirements would be in the public interest; (3) the potential that TAP could
shift certain tariff policy decision-making responsibilities from the Office of the U.S. Trade
Representative to the U.S. Foreign-Trade Zones Board.

Sixth, it examines legislative options for Congress, including possible legislative approaches that
could accomplish the same purposes of TAP without some of the negative implications.
Finally, this report offers some conclusions.
What are U.S. Foreign-Trade Zones?7
US-FTZs are Free Trade Zones
U.S. foreign-trade zones are the U.S. version of what are commonly known as free trade zones. In
general, free trade zones are geographic areas which are physically located inside the boundaries
of a country, but are treated as though they were located outside the country for customs
purposes. U.S. FTZs operate under the direct daily supervision of U.S. Customs and Border
Protection (CBP). In addition, U.S. FTZs remain within the jurisdiction of local, state or federal
governments or agencies.
Because zones exist in many countries worldwide, goods in the making can move from zone to
zone under streamlined customs procedures, having value and parts added until they are at last
complete. No tariffs are owed on goods or materials until they exit the zone system, at which time
the importing company pays any applicable duties.
The U.S. system of foreign-trade zones consists of general purpose zones, which are essentially
secure, multi-user facilities where activities such as warehousing, repackaging, labeling, quality
assurance, manufacturing, and distribution can take place; and special purpose subzones, which
are single-use sites which are geographically separated from general purpose zones but affiliated
with them for recordkeeping and organizational purposes.
History and Purpose of USFTZs
The U.S. Foreign-Trade Zone program was created in 1934 by the U.S. Foreign-Trade Zones Act
(P.L. 73-97).8 It was designed to accelerate U.S. trade in the wake of the restrictive impact of the
Smoot-Hawley Tariff Act of 1930, which raised U.S. tariffs on imported goods as high as 53%.
Other countries had retaliated similarly, and international trade, considered a major force for
economic growth in most countries, came to a near standstill. At the time, the FTZ concept was
controversial because some feared that it would promote imports of cheaper components in the
manufacturing process, and thereby put U.S. components manufacturers at a competitive
disadvantage. As a result, zone activity was initially limited, and manufacturing was not permitted
in FTZs until 1950.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Most zones around the world are “export” processing zones in that they produce for export
abroad. While FTZs in the United States were primarily export processing zones between 1982
and 1995, since 1995 they have become primarily import processing zones in that 84% of the
imported components end up in the United States (2006 FTZ data).9 This is due largely to the fact
that the United States is the world’s largest market and is the destination market for both goods
produced offshore and goods produced at U.S. facilities which compete with offshore facilities.
The system of U.S. foreign-trade zones has evolved greatly over its nearly 75-year history.
Envisioned by some as an engine of export growth, USFTZs have continued to evolve and have
become largely a system for reversing the inverted tariff structures on U.S. imports (higher duties
on imported components than on finished products) under the U.S. Harmonized Tariff Schedule
(HTSUS). Inverted tariff structures can disadvantage U.S. facilities and can be reversed in FTZs
because when assembled goods enter into the customs territory of the United States, the importer
has a choice. He can choose to pay the lower of either the rate applicable to the imported input or
the rate applicable to the finished article.
Benefits of FTZs Today
In recent years, trade agreements (including the multilateral Uruguay Round Agreements in 1993
and bilateral and regional FTAs) have systematically eliminated many inverted tariff structures.
As a result, some observers conjectured a decade ago that FTZs would soon become obsolete.
However, in the last 10 years, usage of the FTZ system has continued to grow. As a share of GDP,
the value of shipments into foreign-trade zones has grown by two-thirds, from 2.2% in 1996 to
3.7% in 2006.10
Despite the overall reduction in tariff rates and the fact that tariff differentials are lower than in
the past, global cost competition in many industries has increased. This means that companies
focus more than ever on squeezing small savings from every part of the production and
distribution process. As a result, although average zone savings may be lower than in the past,
their contributory effect on a U.S. plant’s overall cost reduction efforts may be more significant
than in the past. While the contributory effect will vary by industry, the savings from the use of
zone procedures may have an impact on whether the production costs at a U.S. facility are
competitive with a plant abroad.
Many companies maintain manufacturing facilities throughout the world and are able to shift
production among plants. Any action taken by the U.S. facility to reduce its costs can have an
impact on the maintenance of the activity and associated employment in the United States. In
2006 (most recent data), the total value of imported materials entering the United States through
USFTZs was $159 billion, which represented roughly 9% of the total customs value of all imports
for consumption for that year.11

9 These statistics reflect 2006 data from the most recent 68th Annual Report of the U.S. Foreign-Trade Zones Board to
Congress, December, 2007. See also, CRS Report RL30268, U.S. Foreign-Trade Zones: Current Issues, op. cit., Figure

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Today businesses use zones to save money in at least seven ways aside from avoiding inverted
tariffs: (1) Duty deferral: Duties need not be paid until goods are transferred from the zone to
U.S. customs territory for import; (2) Duty exemption: No duty is payable on goods exported
from a zone or scrapped, or destroyed in a zone; (3) Duty drawback elimination: Zones eliminate
the need for duty drawback—the refunding of duties previously paid on imported and then re-
exported merchandise; (4) Tax savings: Foreign goods and domestic goods held for export in
zones are not subject to state and local ad valorem taxes, such as personal property tax; (5) Quota
storage: Quota restrictions do not apply to merchandise admitted to or stored in a zone until it
exits the zone and is entered into a customs territory; (6) Zone to zone transfer: Merchandise can
be transferred from zone to zone “in bond;”12 and (7) Customs inventory efficiencies: cost savings
(especially cash-flow savings) can occur from zone efficiencies affecting inventory control, such
as “direct delivery” and weekly (instead of individual) entries on zone deliveries.
Details of the TAP Proposal13
The TAP proposal and H.R. 6415 (110th Congress) are substantively the same.
TAP vs. FTAs
FTAs are free trade agreements that are concluded between the United States and one or more
foreign countries to eliminate tariffs and various non-tariff barriers over time (usually 10-15
years), on goods traded between or among them. TAP would permit companies to use existing
FTAs to import third country components at reduced tariff rates. TAP is distinct from FTAs in that
it would (1) permit companies that have applied for and been granted FTZ status for this purpose
to import a specific share of third country components (as permitted under the domestic content
requirements of the specific FTA) into USFTZs; and (2) “substantially transform” them into
finished goods, thus being able to import them into the United States duty-free or at substantially
reduced rates.
Purpose of the TAP Proposal
As mentioned, according to its designers, the main purpose of the TAP proposal would be to
“equalize the unintended consequences of free trade agreements.” NAFTZ argues that U.S. FTAs
never intended to put U.S. facilities that import components from “third” countries at a tariff
disadvantage relative to companies that source either their components or their final products
from FTA countries. A “level playing field,” NAFTZ argues, could keep companies from moving
abroad in order to obtain tariff-free treatment on third country components.14

12 “In bond” refers to the status of merchandise admitted provisionally to a country without payment of duties, either
for storage in a warehouse or for transshipment to another point where duties will eventually be imposed.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

The TAP proposal could then offer companies operating in U.S. FTZs access to “the best and
cheapest suppliers worldwide, as a tonic to domestic manufacturing activity.” In addition,
businesses operating in U.S. FTZs, NAFTZ argues, should be able to obtain components from
foreign sources on terms that are at least as favorable as the terms available to” businesses
operating in FTA partner countries.15 Further, the provision, if adopted, could arguably provide a
reason for some producers to remain in the United States instead of relocating abroad, to the
extent that tariff rates contribute to decisions on where to locate production.
Overview of TAP Legislative Provisions
The TAP legislative proposal is in three parts. Part (a), the main part, would amend the U.S.
Foreign-Trade Zones Act of 193416 to “correct” what the National Association of Foreign Trade
Zones (NAFTZ),17 views as a “problem” or inequality in the Harmonized Tariff Schedule:
Functionally identical components for manufactured goods in this country carry different tariff
rates under the U.S. Harmonized Tariff Schedule (HTSUS) depending on the country or country
group from which they are imported. Components imported from countries with which the United
States has a free trade agreement or trade preference program18 carry a much lower tariff than
goods imported from other countries. To remedy this “problem,” the TAP proposal would permit
importers to pay tariff rates on third country components as if they had been imported from an
FTA country.
Businesses could qualify for reduced tariff treatment on a case-by-case basis if they met two
conditions:
1. The business would have to apply to and be granted U.S. foreign-trade zone
(FTZ) authority by the U.S. FTZ Board. This means businesses would need to go
through the application process and convince the USFTZ Board that FTZ
manufacturing authority and permission to import under a selected FTA would
not be “detrimental to the public interest.”
2. The finished product produced in the zone would need to meet the relevant rules
of origin requirements of any FTA.
Part (b) of the TAP proposal would renumber provisions in the North American Free Trade
Agreement (NAFTA) Implementation Act (P.L. 103-182) to eliminate a provision which denies
NAFTA benefits to goods produced in USFTZs. While this provision was designed to protect
U.S. parts manufacturers from competition from Mexico or Canada, it has arguably served to
encourage certain businesses to drop their USFTZ status and/or relocate to Mexico or Canada

Preferences, the Andean Trade Preference Act, the Caribbean Basin Economic Recovery Act, and the African Growth
and Opportunity Act.

instead. The denial of FTA benefits for firms producing in USFTZs was not included in
subsequent FTAs.
Part (c) of the TAP proposal would set an effective date of 15 days after enactment.
Legislative Language of H.R. 6415 (110th Congress)
The technical language of TAP proposal parts (a), (b), and (c) was as follows:
Part (a)
Part “a,” of the TAP proposal would have authorized businesses to apply for reduced tariff rates
on third country components by adding a small provision to the U.S. Foreign Trade Zones Act [19
USC Sec. 81(c)(a)] after the word “provided” at the end of the paragraph immediately below.
Thus, the proposed new language appears in the indented paragraph below that.
Sec. 81(c)(a) of the U.S. Foreign-Trade Zones Act lists activities that may be undertaken on a
good that has been brought into a U.S. foreign trade zone. This section says that a good may be
“stored, sold, exhibited, broken up, re-packed, assembled, distributed, sorted, graded, cleaned,
mixed with foreign or domestic merchandise, or otherwise manipulated, or manufactured.” It may
then be “exported, destroyed, or sent into customs territory of the United States ... subject to the
laws and regulations of the United States affecting imported merchandise: Provided,” and then
Part (a) of H.R. 6415 read:
further, That if foreign merchandise is incorporated into a finished good, or is processed,
manipulated or manufactured in a zone, and complies with the rules of origin under any
agreement which affects the rates of duty for merchandise and to which the United States is a
party, then upon authorization under this Act, such merchandise shall enter the customs
territory of the United States at the rate of duty provided under the Harmonized Tariff
Schedules of the United States for such merchandise that complies with such rules of origin.
Part (b)
Part (b) of the proposed legislative language would have amended the North American Free
Trade Agreement Implementation Act (P.L. 103-182). It would have renumbered provisions to
eliminate language which denies NAFTA benefits for goods produced in USFTZs for importation
and consumption in the customs territory of the United States. If the currently existing language
included below were removed, NAFTZ users would be eligible to import under NAFTA in the
same way that they are currently eligible to import under all other FTAs. The language which
H.R. 6415 would have eliminated reads:
19 USC Sec. 3332(a)(2)(A) RULES OF ORIGIN: FOREIGN-TRADE ZONES Subparagraph (B) of
paragraph (1) shall not apply to a good produced in a foreign-trade zone or subzone
(established pursuant to the Act of June 18, 1934, commonly known as the Foreign Trade
Zones Act [19 U.S.C.A. Sec. 81a et seq.]) that is entered for consumption in the customs
territory of the United States.
If the above clause were eliminated, the currently existing clause below would then govern tariff
charges on third country components for goods produced in USFTZs:

A GOOD ORIGINATES IN THE TERRITORY OF A NAFTA COUNTRY IF: (B)(i) each nonoriginating
material used in the production of the good –
(I) undergoes an applicable change in tariff classification set out in Annex 401 of the
Agreement as a result of production occurring entirely in the territory of one or more of the
NAFTA countries; or
(II) where no change in tariff classification is required, the good otherwise satisfies the
applicable requirements of such Annex; and
(ii) the good satisfies all other applicable requirements of this section;
Part (c)
Finally, the amendment would have set as an effective date applicable to any merchandise entered
into the United States or withdrawn from warehouse for consumption, 15 days or later after the
date of enactment of the bill.
The FTZ Application Process Under TAP
Under TAP, in order to import third country components at tariff rates and under domestic content
requirements prescribed under any FTA, a business would need to have FTZ manufacturing
authority. To obtain FTZ manufacturing authority a business would have to follow normal
USFTZ procedures and apply to the USFTZ Board19 under guidelines set forth in the Code of
Federal Regulations (15 CFR Part 400), with information showing why its proposed
manufacturing activity would not be “detrimental to the public interest” based on two sets of
criteria.
The first set of criteria is threshold factors. To meet threshold factors, the business would have to
convince the USFTZ Board that FTZ status for purposes of importing components tariff free
under an FTA (1) would not be “inconsistent with U.S. trade and tariff law or policy ... formally
adopted by the Executive Branch;” that (2) FTZ status would not “seriously prejudice U.S. tariff
and trade negotiations or other initiatives;” and that (3) “the activity involves items subject to
quantitative import controls or inverted tariffs, and the use of zone procedures would be the direct
and sole cause of import that, but for such procedures, would not likely otherwise have
occurred.”20
The second set of criteria is economic factors. Under economic criteria, the USFTZ Board would
consider an application for FTZ status based on its net impact on (1) overall employment; (2)
exports and re-exports; (3) retention or creation of manufacturing or processing activity; (4)
value-added activity; (5) import levels of relevant products; (6) import displacement; (7) foreign
competition in relevant products; (8) related domestic industry; and (9) other factors including
technology transfers and investment effects.21

19 There is a fee to apply for FTZs and subzones. Fees are: for general-purpose zones within a port of entry: $3,200; for
subzones, non-manufacturing processing or fewer than 3 products: $4,000; for manufacturing/processing 3 or more
products: $6,500; expansions: $1,600.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

The application process for FTZ authority is lengthy and involved for both the applicant and the
USFTZ Board, and typically takes six months to a year. However, the Board may determine that
it requires additional time based on special circumstances.
Processing any business application for FTZ status requires considerable research and preparation
on the part of the Board, which shall be responsible for publication in the Federal Register of a
notice, invitation for public comment, and time for rebuttal by the applicant. During the process,
Board examiners must also conduct their own research in addition to that presented, conduct
hearings as necessary, review case records and public comments, request evidence, develop
information and evidence necessary for analysis of the threshold and economic factors, and report
on their findings. An examiner’s report, along with the technical report from the local Customs
and Border Patrol (CBP) Port Director, is circulated to CBP headquarters and the Treasury
Department for review and concurrence before final action can be taken by the FTZ Board in the
Commerce Department.
FTZ Board regulations provide that in the course of being considered for FTZ status, the
applicant will be permitted a number of opportunities to provide supplemental information. The
applicant may be notified of deficiencies in the application. If a USFTZ Board decision on the
application is unfavorable, it shall be considered preliminary. The applicant may then provide
additional evidence, which the Board would consider in its review.
If, in its final report, the Board rules against the applicant, based on any of the threshold or
economic factors, it shall deny or restrict authority for the activity. In evaluating the economic
factors, “previous evaluation in similar cases are considered. The net effect is arrived at by
balancing the positive and negative factors and arriving at a net economic effect.” [15 CFR
400.31 (c)].
The Board has, on occasion, denied FTZ status, particularly in certain kinds of cases. More
frequently, the Board implements specific restrictions on approval to address in a targeted manner
issues or concerns. The Board will deny or restrict an application where granting zone status
would handicap other businesses in the industry. On the other hand, once a business in a specific
industry has obtained FTZ status, this could provide a precedent for future applications involving
similar activity. In other cases, the USFTZ has denied zone status based on policy considerations
such as those relating to agricultural products and textiles.
Which Tariff Schedule Rates Would Apply to Businesses Granted
FTZ Status Under the TAP Proposal?
Once a business receives FTZ Board approval to undertake manufacturing under a specific FTA,
as provided by the TAP proposal, it would be eligible for the reduced tariff rates applicable to that
FTA under the U.S. Harmonized Tariff Schedule (HTSUS)22 The tariff rates to be assessed the
business on third country components would be determined as follows:

22 The HTSUS, produced by the U.S. International Trade Commission (USITC), provides the applicable tariff rates and
statistical categories for all merchandise imported into the United States; it is based on the international Harmonized
System, the global system of nomenclature that is used to describe most world trade in goods.
Congressional Research Service
10

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

In the HTSUS, there are three columns representing tariffs assessed to three different groups of
countries. The first is called “Column 1, General.” It shows the “general” rate—often referred to
as either the “most favored nation” (MFR) rate or “normal trade relations” (NTR) rate—assessed
to most countries.23 The second is called “Column 1 Special.” It shows the “special” rates
assessed articles from countries with which the United States has free trade agreements (FTAs);
articles from beneficiary countries under various trade preference laws (i.e., the Generalized
System of Preferences—GSP); articles eligible for duty-free treatment under special programs,
such as the Civil Aircraft Agreement; and articles eligible for the temporary suspension or
reduction of duties. The third is called Column 2. It provides the much higher rate charged to
countries to which the United States does not apply NTR rates. Currently in this list are Cuba and
North Korea.24
With FTZ status, approved businesses would then be eligible to pay the reduced tariff rate in
“Column 1, Special” for the FTA they are authorized to import under, instead of the current tariff
rates under “Column 1, General.”
Potential Real-Life Examples: Importing Without vs. With TAP
The following examples show how a business might save money on tariff assessments under TAP,
when importing under the applicable FTA of its choice.
Example 1: An Auto Assembly Plant Importing Components from China
under the Jordan FTA
As the law currently stands, without the TAP proposal, assume Company A, a foreign-owned,
U.S. based business, has an auto assembly plant in the United States and is operating in an FTZ to
take advantage of the inverted tariff structure for autos. The company imports auto parts from
China (some with a duty rate up to 5%) and assembles the finished vehicle, which has a duty rate
of 2.5%. Under FTZ procedures the company has the choice of paying the duty on the foreign
components in their condition as they leave the zone (i.e., as an assembled car) rather than as they
enter the zone as components. In this way, it is able to reduce its duty rate on foreign components
from 5% to 2.5%. As in all FTZ operations currently, the duty rate comes from the general
Column 1 duty rate in the Harmonized Tariff Schedule of the United States.
Under the TAP proposal as written, Company A could seek authority to apply the rules of origin
(including local content requirements) and duty rate from the U.S. Jordan FTA to the assembled
cars leaving the subzone. Under the Jordan FTA, the duty rate on the cars would be zero,
providing the company with a savings of the 2.5% tariff it pays currently on the value of the parts
imported from China.

23 Column 1 “general” tariff rates differ by industry, and many tariff rates are zero, especially on products not
manufactured in the United States. Components involved in FTZ manufacturing activity generally have duty rates less
than 10%. Average U.S. tariffs, as reported by the World Bank, were 2.7% for 2007. Source: The World Bank. Table 1.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Discussion
In the U.S.-Jordan FTA, no specific rules of origin provision was included for automobiles. As a
result, the Jordan FTA general rules of origin apply. This means that Company A’s finished
vehicles would quality for duty-free treatment under the Jordan FTA if they contained the
minimal amount of 35% U.S. or Jordanian content (including value added by labor). Further, up
to 65% of the value of a finished automobile could be comprised of third-country components,
and the car would still qualify as “originating” under the Jordan FTA. Thus, it is conceivable that
a car with 65% of its value comprised of components from China could have 20% U.S.
components and 15% “value added” through the assembly process in a U.S. factory, and then
qualify as “originating” (duty-free) automobile under the Jordan FTA.
Since negotiators of the U.S.-Jordan FTA (which was signed in 2000) may not have foreseen that
there could be a significant number of vehicle imports from Jordan, the language of the U.S.-
Jordan FTA and the rules of origin negotiations may not have taken into account potential
concerns of the U.S. automobile and auto parts industries. The proposed legislation does not
require that the parts used in the assembly be from Jordan, or that Company A or the industry
have any connection to Jordan to qualify under the Jordan FTA. While the tariff effect from one
company may appear small, the broader impact on U.S. industry could be significant. In addition,
the specific impact of allowing duty-free treatment for the industry may not have been evaluated
during the FTA negotiations.
Company A’s auto assembly is one example of a situation that would be allowed under the TAP
proposal. However, the proposal would allow for similar duty free treatment in any industry
under the rules of any FTA.
Example 2: A Truck Assembly Plant Importing Components Under the
Morocco FTA
As the law currently stands, assume that Company A also has another assembly facility for pick-
up trucks in the United States. Assume further that for this facility, Company A is importing some
components from Japan at a duty rate of 5%. The general column 1 HTS duty rate on the trucks
themselves is 25%. Currently Company A would not benefit from FTZ procedures for reversing
inverted tariffs, since the inverted tariff situation does not exist for trucks (because the U.S. tariff
rate is higher on completed trucks than on its components). Therefore, the company has chosen
not to pursue FTZ designation for the factory.
Under the TAP proposal, however, Company A could apply for subzone status for its truck
assembly operations. In this case, instead of the Jordan FTA (which maintains a 5% duty on the
trucks), assume that the company decides to use the Morocco FTA. The Morocco FTA also
requires only 35% U.S. or Moroccan content (including value added) to qualify under its rules of
origin provision. In addition, the Morocco FTA also has a more favorable—duty-free—rate for
trucks. Company A has no connection to Morocco (as it had no connection to Jordan in Example
1), and none of the parts are imported from Morocco. Further, up to 65% of the value of a
finished truck could be comprised of third-country components, and the truck would still qualify
as “originating” under the Morocco FTA.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Potential Winners and Losers Under the
TAP Proposal
The primary beneficiaries of the TAP proposal would appear, from the analysis that follows, to be
foreign multinational corporations—especially foreign motor vehicle producers, which could save
on their customs duties. Many foreign motor vehicle producers are companies which already do
or could assemble their products in USFTZs from foreign parts sourced from countries like Japan,
South Korea, and the European Union. These are countries with which the United States does not
have free trade agreements, and on whose imports relevant duties may typically be around 2.5%.
Other beneficiaries could include some oil companies that operate refineries in FTZs. Their
savings come from an inverted tariff situation on petrochemical products (which are generally
duty-free) produced from imported crude oil (which is assessed a duty rate of either 5.25 or 10.5
cents per barrel). Currently, the duty rate on gasoline is 52.5 cents per barrel; however, it is duty
free under many FTAs. TAP could increase refinery savings by allowing gasoline produced from
imported crude oil to be entered at a rate of duty-free.25
U.S. FTZs and various FTZ support groups would also stand to benefit from the TAP legislation.
U.S.-owned motor vehicle producers might not stand to benefit from this proposal to the same
extent as foreign-owned motor vehicle producers, because Canada and Mexico are the principal
suppliers of foreign auto parts used to supplement the U.S. made parts used in their U.S. vehicle
assembly operations. Because most of the imported parts used in the assembly plants of the U.S.-
based motor vehicle companies enter free of duty under NAFTA, there was little incentive for
these operations to maintain their FTZ special purpose subzone status following the
implementation of NAFTA.
Potential losers under TAP could be both U.S. parts manufacturers who could lose market share to
imported third country components, and other U.S. manufacturers whose products would compete
with articles assembled in FTZs.
Proponents
The TAP proposal is being promoted by some groups as an economic development and economic
growth tool, with U.S. employment benefits. These groups include some multinational
corporations (especially foreign-owned motor vehicle producers), the National Association of
Foreign Trade Zones (NAFTZ) and some economic development groups.
More specifically, according to NAFTZ, proponents of the TAP proposal include the following:
Abbott, BMW Manufacturing Co., Centrepot International Logistics, Inc., DNP Electronics
America, Eastman Kodak Company, Hitachi Automotive Products, Logistics International, LLC,
Toyota, the Association of International Automobile Manufacturers, Sony Electronics, Valero,
Conoco Phillips, and Daimer. They also include the following FTZs and related support

Opponents
According to the Automotive Trade Policy Council, representing domestic companies Chrysler,
Ford, and General Motors, among other things, the TAP proposal (1) undermines the primary goal
of FTAs and offers FTZ producers a subsidy to continue using non-originating content; (2)
provides an incentive to minimize NAFTA content, since producers would be able to decrease
NAFTA sourcing down to the bare minimum in order to import theoretically cheaper non-
originating content duty-free; (3) further disadvantages U.S. corporations operating outside an
FTZ, because the most favored nation (MFN) duty rates on third country imports would still
apply to those goods not admitted and processed in an FTZ; (4) would not create job growth in
the United States because non-originating goods may become duty-free, thus encouraging the
expanded use of non-originating goods or components. Thus, any job growth would more likely
occur in non-FTA countries; and (5) does not contain an approval process that can limit the
inherent flaws, since any FTZ that wanted to participate in this program could do so by receiving
the approval of the FTZ authority.27
Economic Studies on the TAP Proposal:
Findings and Analysis
Two economic studies have analyzed the possible impact of the TAP proposal. The first, a USITC
staff report examined the potential effect of the proposal on Customs revenues lost through tariff
reduction or elimination. Another study, by two economists Dean DeRosa and Gary Clyde
Hufbauer, examines the potential effect of the TAP proposal on Customs revenue losses and
counter-balancing economic gains.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

USITC Technical Assistance Staff Report28
Findings and Methodology
The USITC staff report estimated the potential annual Customs revenue loss from the TAP
proposal of “at least $437 million (or 1.5% of the total duties receivable for 2005)29 if FTZs were
granted “parity with” FTAs.
This estimated customs revenue loss is based on actual Customs duties paid in 2005 on the
foreign parts and materials that were used in processing operations in FTZs where the processing
operations appeared to satisfy the rules of origin requirements of an FTA.
To estimate the potential loss of Customs revenue resulting from implementation of the TAP
proposal, Commission staff identified:
(a) Companies in General Purpose FTZs and Special Purpose Subzones whose processing
operations would sufficiently transform or add value to imported parts and materials that the
assembled articles would qualify for duty-free entry. This duty-free entry would result from
the fact that the processing met the rules of origin requirements of an FTA; and
(b) the duty paid by each company with “FTA-eligible” FTZ operations on third country
(non-FTA) components.
The USITC staff then tabulated duty paid by each company with operations that would meet the
rules of origin requirements under NAFTA (as a proxy for any FTA) and whose components
imported from third countries could thus be eligible for duty-free treatment under the TAP
proposal.
Results of the USITC study suggest that the TAP proposal could eliminate almost 90% of actual
duties paid by FTZ subzone users, based on 2005 data. The estimate does not take into account
FTZ processing operations that became active in 2006 and 2007. The estimate is based on public
information contained in annual reports submitted by operators of FTZs including FTZ subzones.
The USITC study noted that the TAP proposal may increase the incentive to use dutiable foreign
parts and materials in FTZ processing operations instead of U.S. parts and materials, because the
dutiable foreign parts and materials could qualify for “de facto” duty-free treatment.
The summary of estimated Customs revenue loss by principal sectors, based on USITC staff
tabulations indicates that the sectors responsible for the $437 million estimated total revenue loss
includes motor vehicle assembly ($305 million), petroleum refining ($77 million),

chemicals/pharmaceuticals processing ($19 million), and other assembly operations ($36
million). Thus, under the TAP proposal, the largest estimated customs revenue loss ($305 million
or 70%) would come from the motor vehicle assembly sector.
According to the USITC, 10 companies accounted for 76% of the total revenues paid, and may be
the leading beneficiaries of the proposal for FTZ “parity” with FTAs. All but three of these are
foreign multinational corporations in the automotive sector. These are, in order of the duties they
paid on operations which potentially would be considered FTA-eligible (i.e., potentially TAP-
eligible) because their operations would have met rules-of-origin requirements of NAFTA had
they been performed in Mexico or Canada, combining U.S.-origin and third country inputs:
BMW, Toyota, Honda, Mazda, Nissan, Motiva Enterprises (petroleum refinery), Subaru, Sony
Electronics, Hyundai, and Valero Refining.30
The USITC staff study is static. It predicted customs revenue losses based on a “snapshot” of
actual 2005 FTZ usage by businesses that already hold USFTZ status. It did not take into account
the potential for new FTZ applications if businesses were to take advantage of the TAP proposal,
should it become law. Thus, it did not project ahead to estimate the potential additional Customs
revenues foregone that might occur over the next 5, 10, or 15 years if TAP were adopted.
DeRosa-Hufbauer Study31
The NAFTZ retained two economists, Dean DeRosa and Gary Clyde Hufbauer, to produce “an
economic development study on the impact of TAP on the U.S. economy and manufacturing
sector.” The study estimated the potential impact of TAP over the “medium term” at (1) “over $66
billion in new shipments from the FTZs into the U.S. market;” (2) “the creation of nearly 95,000
new manufacturing jobs in FTZs;” (3) a total annual gain to the U.S. economy of $530 million;
(4) “higher pay and living standards for manufacturing and other zone workers;” and (5) “clear
evidence that the proposal will benefit the U.S. economy in both job increases and U.S. business
growth.”32
Findings and Methodology 33
The DeRosa-Hufbauer study bases its estimates on a gravity model (which predicts bilateral trade
flows based on the GDP levels of trade partners and the geographic distances between them).
Using this model, it assumes that the TAP proposal will shift output from non-zone to zone

production, amounting to a 13% (or $66 billion) increase in shipments from zones, in 2006, and a
counter-balancing decline in shipments from locations outside of FTZs.
Estimates of Economic Losses: Customs Revenues Foregone
The DeRosa-Hufbauer study’s gravity model estimates foregone customs revenues to the U.S.
economy from the TAP proposal at $186 million per year (or 18% of 2005 Customs revenue), of
which $146 million, or nearly 80% (similarly to the USITC staff study) would be in the motor
vehicle sector—notably vehicles, other transport equipment, and related parts and accessories.
This estimate of Customs revenues foregone, at $186 million, is less than half the estimate
reported by the USITC Staff study of $437 million based on 2005 data. The different estimates
reflect the difference in methodology between the two studies.
While the DeRosa-Hufbauer study obtained its estimate from economic modeling, based on
imports actually arriving from present and prospective FTA partners, the USITC staff obtained its
numbers by sorting through public information contained in annual reports submitted by
operators of FTZs and subzones and actually tabulating tariffs paid on third country components
by companies that would be eligible to apply for FTZ status under TAP. This estimate is based on
calculations that, based on NAFTA rules of origin, the processing/assembly in the FTZ of third-
country parts and materials with U.S.-origin content and labor would qualify the processed or
assembled good leaving the FTZ for duty-free entry into the United States under NAFTA had the
processing or assembly occurred in Mexico or Canada.
Estimates of Economic Gains
The DeRosa-Hufbauer study mentions three kinds of gains to the U.S. economy: job gains to
FTZs, annual wage gains of $394 million and producer gains of $136 million, for a total benefit
to the U.S. economy of $530 million. It finds that these gains “dwarf [estimated] foregone
customs revenues” at $186 million.34
Job Gains. The DeRosa-Hufbauer study estimated that the TAP proposal would shift 95,000
additional full-time equivalent jobs from a location outside FTZs to a location inside FTZs, as
existing businesses gain zone status.35 This number, accounts for about 0.7% of all manufacturing
employment in 2005. It is not clear from the study whether any of these FTZ job gains would
represent actual job gains to the company (as opposed to job gains to FTZs which would result
from a simple switch of the company from non-zone to zone status).
The DeRosa-Hufbauer study acknowledges that this shift of workers from non-zone to zone
status would not change total U.S. employment. Citing the DeRosa-Hufbauer study, NAFTZ
claims the addition of 90,000 U.S. manufacturing jobs.”36

34 Dean A. DeRosa and Gary Clyde Hufbauer, op. cit., p. 1, abstract.
35 This would include 45,000 jobs in the transport equipment, 14,000 jobs in machinery production, and 14,000 jobs in
mineral products. The jobs with new subzone status would be located primarily in Ohio, Tennessee, Texas, and Florida.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Wage Gains and Producer Gains. DeRosa-Hufbauer use a 95,000 figure as the basis for their
argument that the TAP proposal would result in U.S. wage gains of 7% or $394 million ($179
million in the transportation sector and $82 million in the petroleum sector.)37
DeRosa and Hufbauer arrived at this 7% estimate using research published by Lewis and
Richardson in 2001, incorporating data from the late 1980s and early 1990s. Lewis and
Richardson’s research found that on average, workers in export-oriented multinational firms with
foreign investment backing operating in the U.S. enjoy earnings that are about 7% higher than
their counterparts in the same U.S. industries.38 However, DeRosa and Hufbauer apply this 7%
wage differential in a different way—to workers in primarily import-oriented firms.39
The estimate of $82 million in wage gains in the petroleum sector (the second largest set of wage
gains) is problematical because these projected gains appear to be attached to new jobs in the
petroleum sector that the authors suggest are likely not to materialize because anticipated
investment and expansion in that sector are unlikely to occur, reflecting “the complexities of the
petroleum-based fuel blends demanded in the U.S. market, [and] increasingly stringent
environmental standards regulating the construction of new refineries.”40 As a result, a projected
elimination of the 0.01% trade-weighted tariff on crude petroleum might not yield sufficient cost
savings to promote the investment required to build more petroleum refineries. While this might
lead to producer gains (estimated at $136 million), if these producer gains do not lead to new
investment, there would likely not be significant increases in employment or wages relating to the
TAP legislation.
Policy Analysis of the TAP Proposal
If FTZ status were obtained and permission thus granted, the following conditions would come
into play for TAP beneficiaries:
• The beneficiary company under TAP would be entitled to reduced or zero tariffs
on third country components so long as the completed good leaving the FTZ met
the rules-of-origin requirements of any FTA.
• The beneficiary company would not need to import any components from or
through the FTA country under whose FTZ goods were being imported.
• Neither the beneficiary company nor the U.S. government would be required to
notify the country whose FTA was being thus used, that this was occurring.

37 However, some wage gains could result if tariff reductions achieved by businesses were passed on to workers.
38 Lewis, Howard III, and Richardson, J. David. Why Global Commitment Really Matters! Institute for International
Economics, Washington, D.C., 2001, p. 29-31.
39 Other issues are: (1) the research quoted is nearly 20 years old, over which time the capital structure of businesses—
especially multinational businesses—has changed considerably; and (2) the Lewis and Richardson study, in a footnote,
pointed out that different wage premiums are largely explained by the heavier capital intensity of plants backed by
foreign investors, and that premiums vanish if plants are made comparable in their machinery and equipment per
worker as well as in industry and location. Since the plants are already in existence and there would not necessarily be
any capital changed involved as a result of a shift from non-FTZ to FTZ status, and workers themselves would not
necessarily change jobs or employers or locations, the arguments for wage increases might not apply.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

• The beneficiary company could meet the rules-of-origin requirements of the
selected FTA entirely by using U.S. components and labor. Remaining non-
domestic components could come from any FTA or non-FTA trading partner.
• Thus, through this proposal, FTA benefits could be extended to non-FTA
countries. That is, components from non-FTA countries could potentially receive
import benefits to which they would not otherwise be entitled.
• The only U.S. “gatekeeper” regulating or intervening in this practice would be
the U.S. foreign-trade zones Board (FTZ Board) which could restrict or prohibit
zone activity “that in its judgement is detrimental to the public interest.” (15 CFR
400.31).
Potential Trade Policy and Administrative Implications
The TAP proposal is a complex issue, with both economic and policy implications. Policy effects
of TAP could include the following:
Businesses Otherwise Required to Pay Tariffs Could Obtain a
Large Tariff Benefit
Businesses likely to reap the most benefits from reduced tariff obligations under TAP would be
multinational corporations headquartered in Asia and Europe, with production operations located
in the United States that source components from the home country. Based on manufacturing
subzone activities in 2005, the USITC estimated that subsidiaries of 15 German, Japanese, and
Korean motor vehicle and parts producers would account for 70% of the revenue lost to the U.S.
Treasury if the current TAP proposal were enacted.41
Effects on Trade and Diplomatic Relations With U.S. FTA Partner Countries
and Third Countries
If the TAP proposal were approved by Congress, it could affect trade with FTA partner countries
and third countries. FTAs negotiated between the United States and various partner countries
could be used to allow non-FTA countries to reap the benefits of the FTAs in terms of duty-free
access to the U.S. market without providing equivalent access to exports from the United States.
This would reduce the advantage of FTA partners in the U.S. market, undercutting the value of
the agreements that they signed with the United States. The TAP legislation arguably would be a
disincentive for potential future FTA partners to negotiate a free trade agreement with the United
States.
TAP Would be Like a Broad Trade Preference Program
If adopted, the TAP could offer equivalent tariff treatment on certain goods to suppliers in all
foreign countries and to all U.S. businesses incorporating those goods under certain
circumstances in FTZ subzones. The TAP proposal would, in essence, be another trade preference

report, op. cit.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

program, offering tariff reductions on a business-by-business basis. As with other trade preference
programs, the TAP program would offer unilateral tariff reductions without requiring any
reciprocating tariff reductions by other countries, and without investment protections for U.S.
businesses that FTAs would carry.
Dilution of USTR Authority; Shifting of Some USTR Responsibilities to the
USFTZ Board
TAP could decrease the usefulness to USTR of being able to cite the potential elimination or
reduction of U.S. tariffs on specific articles as a “carrot”—an incentive for trading partners to take
action of interest to the United States. Such action could include improving access for U.S.
exports, protecting worker rights, improving protection of intellectual property, or participating in
multilateral efforts to eliminate tariffs on a sectoral basis (known as “zero for zero” agreements).
Responsibility for determining eligibility for duty-free access to the U.S. market through FTZ
manufacturing authority would flow to the USFTZ Board located in the Department of
Commerce’s Import Administration.
The FTZ Board Could Be Swamped with FTZ Applications
It is not clear how the FTZ Board would handle its charge to determine whether the use of FTZs
in this way would be in the “public interest.” If, in fact, the 144 companies that the USITC staff
report identified as TAP-eligible manufacturing operations were to immediately assert to the
USFTZ Board that duty-free treatment for imported components used in their FTZ operations
would be in the public interest, the task of verifying the assertion could overwhelm the small
board.42 In addition, new applications would likely add to this overload as businesses calculate
the potential costs and benefits of applying for FTZ status to achieve tariff savings on third
country components.
The TAP Proposal Could be a Problem with the WTO
The TAP proposal could also potentially violate U.S. obligations under the World Trade
Organization (WTO). Pursuant to the WTO, countries cannot normally discriminate between their
trading partners. This principle is known as “most-favored-nation” (MFN) treatment. Some
exceptions, however, are allowed. Specifically relevant to this discussion, countries are permitted
to establish free trade agreements that afford more favorable treatment (e.g., lower tariff rates) to
goods traded between parties to the agreement. Because, if enacted, the TAP proposal could
possibly result in the granting of FTA benefits to non-FTA members, it could arguably be
interpreted as providing more favorable treatment to some importers for which no WTO
exception applies. As a result, the proposal could potentially be challenged through the WTO’s
dispute settlement process if a WTO Member determined that the effect would be severe enough
to warrant bringing the dispute.43

42 The board consists of the Secretaries of the U.S. Commerce Department and Treasury (whose designees—the
Assistant Secretary of Commerce for Import Administration, and the Deputy Assistant Secretary of the Treasury for
Tax, Trade, and Tariff Policy—typically function for them; plus the Executive Director and a professional staff of
seven.

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Options for Congress
Take No Action
Congress has several options available to it. First, Congress could have decided to take no action.
If this were to occur, the FTZ program would likely continue as a way for producers to save
money through continued use of zones for purposes such as righting “inverted tariffs,” duty
deferral, duty exemption, duty drawback elimination, tax savings, quota storage, zone to zone
transfer, and customs inventory efficiencies.
Include Only Part (a) of the TAP Proposal
If Congress had adopted only Part (a) of the TAP proposal, a company could apply to the USFTZ
Board for permission to import components from third countries under any FTA except NAFTA.
This is because the NAFTA implementing legislation still prohibits NAFTA benefits to businesses
producing in USFTZs. Any company wishing to import under NAFTA would thus need to import
under another FTA instead, and meet that other FTA’s rules of origin requirements.
Include Only Part (b) of the TAP Proposal
Congress could have decided to approve Part (b) of the TAP proposal, but not Part (a). If
Congress were to adopt Part (b) but not Part (a), businesses manufacturing in USFTZs could at
last receive NAFTA benefits on components they import from Mexico or Canada. This would
make the NAFTA implementing legislation comparable to that of subsequent FTAs.
Include Parts (a) and (b)
If Congress had adopted both parts (a) and (b)—the entire TAP proposal—businesses could
import components from third countries under any FTA, including NAFTA.
Consider Other Amendment
Finally, Congress could have considered another amendment(s) to modify or replace the TAP
proposal.
If the objective were to reduce or eliminate tariffs on components incorporated into goods
produced in the United States, one possibility would be to do it more directly. Legislation could
be constructed to eliminate tariffs on components incorporated into other goods in the United
States, so long as the final product met rules of origin requirements designed specifically for the
legislation. These rules could call for a flat percent of domestic content (e.g., somewhere between
35 and 65%), or specific domestic content shares for different products. The importer would have
to certify to Customs and Border Protection that the value-added requirements of such legislation
had been met.
Congressional Research Service

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

Such an amendment might include further qualifications. For example, the legislation could also
limit the TAP benefit eligibility to components imported from countries that afford reciprocal
treatment for U.S. components exported to certified assembly operations in the partner country.
Such a proposal would (1) not directly involve current FTA partners; and (2) not overload the
USFTZ board.
As with all trade legislation, however, there would still be winners and losers. Losers could still
be the volume of trade with current FTA partner countries, whose trade with the U.S. could be
diverted to other countries. Losers could also be U.S. parts producers. On the other hand, opening
up the U.S. economy to reduced or zero tariffs on components imported from third countries
could stimulate a new round of U.S. business process reorganizations, as companies look for new
ways to cut production costs while maintaining a required level of U.S. value added in parts and
labor.
Conclusions
Conclusions regarding the TAP proposal can be divided into two groups: economic conclusions
and policy conclusions.
Economic Conclusions
Economic conclusions include the following:
• The primary benefit of TAP would be tariff benefits for corporations that source
components from third countries.
• Loses in customs revenues could be between the $186 million estimated by the
DeRosa-Hufbauer study and $437 million estimated by the USITC staff study.
However, neither study projected ahead to take into account the extent to which
U.S. businesses might re-engineer their products to take advantage of small tariff
savings per item produced—savings which, on a large production scale, could
end up being considerable. In addition, the estimated loss in customs revenue
figures were based on existing levels of zone activity. Any shift to FTZ
manufacturing (as exemplified through the shift of an estimated existing 95,000
U.S. jobs into zones in the DeRosa-Hufbauer study) would substantially increase
the loss in customs revenue.
• The TAP proposal could result in a potential decrease in demand for U.S.-made
parts as a result of any tariff-free benefits for third country components. Neither
the USITC staff study nor the DeRosa-Hufbauer study addresses this issue or
estimates its impact. The potential decrease in demand could be considerable
since it could spread across many industries. A study estimating this impact
would be useful.
• Estimated employment increases of 95,000 in the DeRosa-Hufbauer study would
not represent a net gain to the U.S. economy. They would represent primarily a
shift among existing plants from non-FTZ to FTZ status. Some additional job
shifts from elsewhere in the economy into plants operating in zones, however,

22

U.S. Foreign-Trade Zones: Trade Agreement Parity (TAP) Proposal

could result if businesses were to pass cost savings from tariff elimination on to
consumers in the form of lower prices.
• Estimated wage gains of 7% for certain jobs, for a total of $394 million
nationwide, were based on a 20-year old study which found that workers
producing for export from multinational corporations enjoyed higher wages. The
data are then applied to workers producing primarily for import.
• Some producer gains may not materialize; however, profits could increase The
DeRosa-Hufbauer study estimate of producer gains of $136 million annually
from the TAP proposal, if it were adopted, may overstate investment benefits in
some firms, as the authors acknowledged. For example, elimination of the
approximately 0.01% duty (trade-weighted ad valorem equivalent) on crude
petroleum under TAP may not convince petroleum refiners to expand their
capacity. Instead, the primary economic benefit of TAP may be increased profits
to foreign-based multinational corporations which would be afforded tariff
savings on third-country imports.
Trade Policy Conclusions
Among policy conclusions are the following:
• The potential effects the TAP proposal generally seeks to address are widely
considered to be the intended consequences of FTAs: the United States extends
preferential tariff treatment to components from an FTA partner country in
exchange for that country’s lowering of its tariff rates on U.S. products.
• TAP would give FTA benefits to non-FTA components, with likely effects on
trade and diplomatic relations with FTA partner countries and with third
countries. There could be a negative impact on diplomatic relations with FTA
partner countries, since FTA benefits would be extended to non-FTA partner
countries without the permission or knowledge of the partner country whose FTA
would be used in this way. This could put the FTA partner country at a
competitive disadvantage vis-a-vis other countries whose businesses would be
using the FTA without the partner country’s permission, to import third-country
components duty-free. Conversely, third countries which have not negotiated
FTAs with the United States could reap the benefits of FTA duty rates without
any compensating concessions on their duty rates for American goods.
• TAP could complicate diplomatic relations with FTA partner countries, since FTA
benefits would be extended to non-FTA partner countries without necessarily any
notification to or consultation with the partner country whose FTA would be used
in this way.
• TAP would in essence create a new trade preference program offering all
countries tariff benefits equal to those included in FTAs, with permission granted
by the FTZ Board on a business case-by-case basis.
• TAP would extend FTA benefits to non-FTA countries, without requiring
reciprocal tariff reductions of the part of the country whose companies are
supplying components for FTZ subzone assembly operations.

Administrative Policy Conclusions
• TAP would remove in a de facto sense, certain tariff policy responsibilities from
the Office of the U.S. Trade Representative and delegate them to the U.S.
Foreign-Trade Zones Board. It would create a new category of administratively
determined tariff beneficiaries—specific businesses.
• TAP could potentially overload the USFTZ Board with investigations to
determine whether granting duty-free entry of components for use in assembly
operations meets the “public interest” mandate of the TAP legislation. The FTZ
Board could also face many new requests for approval of FTZ manufacturing
authority.
Ultimately the potential costs and benefits of TAP if it were adopted, as well as its effects, would
depend on the extent to which businesses would apply for FTZ status to take advantage of
potential tariff relief offered. Some crucial questions for further research are: Would adoption of
the TAP proposal encourage businesses with assembly operations in the United States to
substitute imported components for domestic components? To what extent would adoption of the
TAP proposal impact U.S. parts producers and suppliers? To what extent would TAP encourage
businesses to stay and expand in the United States instead of moving operations abroad?
