Tariff Modifications: Miscellaneous Duty
Suspension Bills
Vivian C. Jones
Analyst in International Trade and Finance
Foreign Affairs, Defense, and Trade Division
Summary
Any modification of the tariff code must be approved by Congress, and constituents
sometimes request that Members introduce bills seeking to suspend or eliminate tariffs
on certain imports. In recent congressional practice, the House Ways and Means and
Senate Finance committees have consolidated duty suspension bills into larger pieces
of legislation known as miscellaneous tariff and technical corrections bills.
On March 10, 2005, the Chairman of the House Ways and Means Trade
Subcommittee, Representative E. Clay Shaw, announced the Subcommittee’s request
that all Members who plan to introduce tariff legislation or miscellaneous corrections
to trade laws do so by April 28, 2005, so that the Subcommittee would have sufficient
time to evaluate and consider the bills. This announcement probably indicates that the
House will consider a miscellaneous tariff bill during the first term of the 109th
Congress. This report will be updated as events warrant.
Background
The Constitution gives Congress the primary authority over trade policy; therefore,
Congress must approve any modifications to the tariff code. Constituents, often
representing industry associations, will sometimes ask Members of Congress to introduce
legislation proposing to reduce, repeal, or temporarily suspend duties on certain imports.
In recent years, 85% to 90% of these requests have been related to chemicals or other
components used in the manufacturing process.
Since the 1980s, the House Ways and Means and Senate Finance committees, the
primary committees of jurisdiction on trade matters, have tended to incorporate duty
suspensions into larger pieces of legislation that also include instructions to U.S. Customs
and Border Protection (CBP), and minor technical corrections or conforming amendments
to trade laws. Most of the time, comments on the legislation from industry and the
Administration are solicited at the subcommittee level prior to drafting the legislation
rather than holding hearings. This is probably due to the increasingly large number of
duty suspension bills introduced in recent Congresses.

This report focuses briefly on the reasons that duty suspensions have merited
congressional attention and on the current procedure by which congressional committees
evaluate and select commodities for inclusion in more comprehensive legislation.
Duty-Suspension Legislation
The introduction of miscellaneous duty suspension and technical corrections
legislation in its current omnibus format appears to have originated in the 97th Congress
with H.R. 4566 (Gibbons), which proposed to “reduce certain duties, to suspend
temporarily certain duties, to extend certain existing suspensions of duties, and for other
purposes.”1 Prior to that date, even though committee hearings were often held on several
duty suspension bills as a group, Congress often acted on them individually. A list of
miscellaneous duty suspension legislation from the 97th to the 108th Congresses is found
in Table 1, below.
Legislation in the 108th Congress. On March 4, 2003, H.R. 1047 (Crane), the
Miscellaneous Trade and Technical Corrections Act of 2003 was introduced. The bill
sought to grant approximately 300 duty suspension and 100 extensions to duty
suspensions already in force. The bill passed the House on March 5, 2003 by a vote of
415-11. On March 20, 2003, the Senate Finance Committee reported a similar bill, S.
671. According to Senate staff, several “holds” or objections to the Senate bill delayed
its passage. On March 4, 2004, the Senate amended H.R. 1047 by striking all language
after the enacting clause, and inserting the text of S. 671, as amended. The bill was
passed by unanimous consent on the same date.
On October 8, 2004, the House passed the conference report to H.R. 1047 (H.Rept.
108-771) without objection, but the bill stalled in the Senate over opposition to a measure
that would grant permanent normal trade relations status to Laos. In a November 5, 2004
letter to Senate leadership, Senate Finance Committee Chairman Charles Grassley,
Ranking Member Max Baucus, and 39 other Senators expressed strong support for
passage of the conference report prior to adjournment of the 108th Congress.2 The Senate
subsequently passed the conference report on November 19, 2004, and the President
signed the bill on December 3, 2004 (P.L. 108-429, 118 Stat. 2434).
109th Congress. On March 10, 2005, Representative E. Clay Shaw, Chairman
of the House Ways and Means Trade Subcommittee, announced the Subcommittee’s
request that all Members submit tariff legislation or miscellaneous changes to trade laws
by April 28, 2005.3 This announcement probably indicates that a miscellaneous trade bill
will be considered in the House during the first term of the 109th Congress.

Policy Considerations
Tariffs on most U.S. and foreign goods have been revised gradually downward over
a period of almost seven decades as a result of bilateral and multilateral trade
negotiations. Many economists believe that lower foreign tariffs benefit U.S. exporters
because they make U.S. goods more competitive in foreign markets, and that lower U.S.
tariffs can benefit domestic manufacturers and consumers because the cost savings on
imported goods may be passed on to other “downstream” producers, ultimately resulting
in lower costs of the finished products. However, tariffs are also sometimes used
protectively in an effort to help domestic industries remain competitive, especially those
considered vulnerable to foreign imports, such as agriculture, textiles, and steel.
According to subcommittee staff, temporary duty suspensions are generally
considered for inclusion in a larger trade bill if the corresponding goods or materials are
deemed “noncontroversial” or “noncompetitive,” meaning that (1) there is no domestic
producer objecting to the duty suspension; (2) the suspension or reduction of the tariff is
seen to be in the interest of U.S. “downstream” producers (and theoretically, consumers);
and (3) the volume of imports and corresponding revenue loss are relatively small
(generally not more than $500,000 per commodity).
Congress and the Administration usually favor the temporary nature of these
measures because more permanent revisions of the tariff code can then be used in trade
negotiations to seek reciprocal benefits for U.S. exports. In addition, if a domestic
company later emerges that desires to manufacture the targeted commodity, the expiration
of the duty suspension could make prices of the domestic product more competitive in the
U.S. market.
Reasons for Passage. Since Congress has, in recent years, tended to confine its
consideration of duty suspensions to noncontroversial requests, requests that seem to give
one domestic corporation or industry a competitive advantage over another, or that meet
with opposition from a domestic producer are generally not considered. However, there
are other reasons that duty suspensions have merited congressional attention.
First, in some cases, a higher tariff rate may apply to a relatively noncompetitive
product that is aggregated in a Harmonized Tariff Schedule (HTS) heading or subheading
with related commodities that are considered more competitive. This is often the case
where certain chemical compounds are concerned.
Second, there may be no current domestic production of a commodity, or it may not
be produced in sufficient quantities to satisfy domestic demand. As a result, U.S.
manufacturers who use the commodity in their products may have to depend on imports.
In this case, a duty suspension would lower the overall price of the good, and the savings
could be passed along to “downstream” producers and consumers.
Third, the duty rate of an important component of a domestic product may be higher
than the duty on the comparable imported finished good. One example of this was a case
in which casein button blanks used by U.S. button manufacturers were imported at 22.1%
ad valorem, while finished buttons were imported at a rate of 6.9% ad valorem. Domestic

producers complained that they were put at a competitive disadvantage vis-a-vis foreign
manufacturers of the same product because of the higher duty rate for the raw material.4

Fourth, multinational corporations sometimes manufacture products at a foreign
subsidiary and import them for use in an additional manufacturing process. For example,
a U.S. automobile manufacturer may fabricate some of its car parts in a plant in
Guatemala, and then import the parts into the United States, where it assembles the
finished product. Congress sometimes considers duty suspensions even if there is a
similar product manufactured domestically because since the importing company also
manufactures the product, it is not likely to purchase the item from the U.S. producer.
Fifth, nonprofit associations may wish to import an item and request a one-time
suspension of duties. For example, churches have sometimes requested one-time duty-
free status for pipe organs purchased from Europe, and an educational institution has been
allowed duty-free status for parts used in the construction of a telescope.
A sixth, less frequent, reason for congressional approval of duty suspension
legislation is compelling national interest. For example, in 1942, the 77th Congress
considered the suspension of import duties on all scrap metal because the War Production
Board predicted a shortage of as much as 6.5 million tons of metal necessary for the
defense industry to operate its open hearth and electric furnaces at full capacity.5 The
Board recommended that all barriers to importing these metals be dropped so that all the
necessary raw materials could be gathered to create the weapons and vehicles necessary
to win the war. The bill passed both Houses by unanimous consent.
Current Committee and Legislative Procedure
Current congressional committee practice seems to involve reporting out one
omnibus piece of legislation per Congress providing for temporary duty suspensions and
making minor technical changes to trade laws. In recent Congresses, committees of
jurisdiction have tended to request comments from interested parties at the subcommittee
level, rather than holding hearings on these bills.6
In the 107th Congress, for example, House Ways and Means Trade Subcommittee
Chairman Philip Crane sent out a Dear Colleague letter dated March 7, 2002, to all
Members requesting that those planning to introduce duty suspension legislation do so by
the 16th of April. A similar letter was sent out by the Senate Finance Committee seeking
legislation by April 12. Since the duty suspension package did not pass during the 107th
Congress, the provisions were included in H.R. 1047 and S. 671, the miscellaneous duty
suspension bills introduced in the 108th Congress.

Agency and Executive Review. After duty suspension bills are introduced and
referred, they are reviewed by subcommittee staff, who, in turn, solicit comments from
the Administration (including the United States Trade Representative, CBP, and the
Department of Commerce), and the ITC. Committee staff sometimes solicit public
comments directly,7 or may do so through Administration channels. Duty suspensions
that might be considered controversial are generally filtered out in this process.
Congressional staff have commented that committees also prefer that the Congressional
Budget Office (CBO) cost estimates on duty suspensions are essentially revenue-neutral,
or reduce federal government revenues by no more than $500,000.
Role of the International Trade Commission. Generally, the ITC is the first
agency that provides a response to the committees, and appears to be the only one
required to do so by statute.8 The ITC usually contacts companies and industry groups
through its Office of Industries (either directly or by sending out a questionnaire) to solicit
responses from interested parties, especially looking for U.S. producers of the same or
like commodities targeted for duty suspensions. In 2002 (H.R. 1047 includes almost the
same commodities), due to the over 600 commodities represented, the ITC instead
published a Federal Register notice asking for non-confidential information from
interested parties.9
The ITC prepares a report on each commodity providing information on the amount
and volume of trade, estimated revenue loss if the tariff is suspended, and technical
information including proper nomenclature, HTS heading, and Chemical Abstract (CA)
number, if applicable. The ITC forwards the reports to the congressional committees and
shares them with relevant agencies in the Executive Branch.
Administration’s Response. The overall Administration response is generally
coordinated by the Department of Commerce (Commerce). Analysts at Commerce also
research the targeted commodities, either independently or in conjunction with the ITC
response, depending on time frame.
With regard to comments on duty suspensions, Commerce generally does not object
unless a U.S. producer of a targeted commodity is found. In most cases, intra-company
transfers are also not opposed, even if a like product is manufactured in the United States.
Customs and Border Protection also comments on duty suspensions, largely by
recommending reclassifications or changes in nomenclature for ease in administering the
proposed tariff changes. CBP has a formal agreement to share this information with the
ITC, and may also provide information to other agencies. However, if certain measures
impact CBP more directly (e.g., changes in duty drawback statutes, legislative responses
to CBP rulings, liquidations and reliquidations, or permanent duty suspensions), CBP
will generally communicate directly to the committees on a confidential basis.

the Duty on Certain Steam or Other Vapor Generating Boilers Used in Nuclear Facilities.
8 Section 332 of the Tariff Act of 1930 (19 U.S.C. 1332), as amended, charges the ITC with
conducting studies and investigations at the request of the President, the House Committee on
Ways and Means, or the Senate Committee on Finance.

The Office of the United States Trade Representative may also comment on
individual duty suspension bills, but generally focuses on larger issues in the legislation
that would more permanently affect U.S. trade policy.
