What are anti-dumping duties?

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.

Will anti-dumping duties apply to my product?

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.
