Antidumping Investigation
Investigations conducted by the U.S. Department of Commerce and the USITC under the U.S. antidumping law, Title VII of the Tariff Act of 1930 (19 U.S.C. 1673 et seq.), almost always on the basis of a petition filed with Commerce and the USITC on behalf of a domestic industry. If Commerce determines that the subject goods are being sold in the United States at less than fair value (dumped), and the Commission determines that a U.S. industry is materially injured or threatened with material injury or that the establishment of any industry is materially retarded by reason of such sales at less than fair value, Commerce will issue an antidumping duty order that imposes an antidumping duty on such imports in an amount equal to the margin of dumping.
