The ITC and the U.S. Department of Commerce are responsible for conducting antidumping (AD) and countervailing duty (CVD) (subsidy) investigations and five-year (sunset) reviews under Title VII of the Tariff Act of 1930.  Under this law, U.S. industries may petition the ITC and Commerce for relief from unfairly priced (dumped) and subsidized imports.  Dumping occurs when a foreign producer sells a product in the United States at a price that is below that producer's sales price in its home market, or at a price that is lower than its cost of production.  Subsidizing occurs when a foreign government provides financial assistance to benefit the production, manufacture, or exportation of a good.  If the Department of Commerce finds that an imported product is dumped or subsidized and the ITC finds that a U.S. industry producing a like product is materially injured or threatened with material injury, an antidumping duty order or countervailing duty order will be imposed to offset the dumping or subsidies.

When an antidumping or countervailing duty order is imposed, Commerce instructs the Bureau of Customs and Border Protection (Customs) to assess antidumping or countervailing duties on imports of the product into the United States to offset the unfair trade practice.  Under the Continued Dumping and Subsidy Offset Act of 2000 (CDSOA or Byrd Amendment), antidumping and countervailing duties collected are distributed annually to affected domestic producers for qualifying expenditures incurred.  Following imposition of an AD or CVD order, the ITC provides Customs with a list of affected domestic producers (those producers who publicly expressed support for the petition during the investigation); those producers can then submit certifications to Customs of qualifying expenditures in order to receive a pro rata share of the annual distribution of duties collected.

Commerce and the ITC review each outstanding antidumping and countervailing duty order every five years to determine whether revocation of the order would be likely to lead to continuation or recurrence of dumping or subsidies and of material injury within a reasonably foreseeable time.  If both agencies make affirmative determinations, the order is continued for another five years; if not, the order is revoked.

This site provides a schedule of key dates and events, staff contacts, Federal Register notices, and news releases for each original antidumping and countervailing duty investigation and five-year (sunset) review, and listings of past, present, and future five-year (sunset) reviews by month of institution, product, and country.  The site also provides generic and case-specific questionnaires for antidumping and countervailing duty investigations and reviews; commissioner opinions in each completed investigation and review; lists of outstanding AD and CVD orders by country, date, and product; historical case statistics for investigations and reviews; publications of interest to participants in investigations such as the Antidumping and Countervailing Duty Handbook and An Introduction to APO Practice in Import Injury Investigations; information on the Byrd Amendment; and links to other related government web sites.
