Antidumping and Countervailing Duty Investigations
The Customs Service assesses antidumping duties and/or countervailing duties on imported merchandise.
Subsidization occurs when a government provides countervailable financial assistance to benefit the production, manufacture, or exportation of a good.
When an antidumping or countervailing duty order is imposed, Commerce instructs the Bureau of Customs and Border Protection (Customs) to assess antidumping and/or countervailing duties on imports of the product into the United States to offset the unfair trade practice.
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.
Commerce determines whether the alleged dumping or subsidizing is occurring, and if so, the margin of dumping or amount of subsidy.
The USITC determines whether the U.S. industry is materially injured or threatened with material injury by reason of the imports under investigation.
If both Commerce and the USITC reach affirmative final determinations on their individual questions, then Commerce will issue an antidumping duty order to offset the dumping or a countervailing duty order to offset the subsidy.
The U.S. Customs and Border Protection maintains a searchable database of antidumping and countervailing duty messages that can be retrieved based on simple or complex search characteristics using keywords and Boolean operators. The messages are segregated by Antidumping or Countervailing and span the years 1992 to present.
