Anti-dumping duties are assessed to mitigate the impact of dumping, which is when foreign manufacturers sell products in the United States at a lower cost than their fair value.
Anti-dumping duties are priced to make up for the gap between foreign manufacturer pricing and fair market value.
If applicable, anti-dumping duties may be anywhere from 0% to 550% of the commercial invoice value.
This depends on the country of origin and the type of product.
The U.S. International Trade Commission and the U.S. Department of Commerce oversee anti-dumping duties. For an official list of products affected, visit the International Trade Administration's website.
Manufacturers or companies can file petitions to these two bodies if they find a foreign manufacturer selling under fair market value or a foreign government subsidizing manufacturers. The USITC and DOC will review the petition and conduct investigations to determine its validity. They will then instruct U.S. Customs to assess duties accordingly.
