Trade & Tariffs
Antidumping Duty
A targeted tariff on imports sold below fair value, protecting a specific domestic industry from underpricing.
Also known as: AD/CVD, Antidumping and Countervailing Duties
- What it is
- Antidumping duties are tariffs imposed when foreign producers sell goods in the U.S. below fair value, injuring domestic industry. Countervailing duties offset foreign subsidies. Commerce and the International Trade Commission run the investigations.
- How it moves markets
- AD/CVD orders raise import costs on specific products from specific countries, advantaging the U.S. petitioners that filed the case. Preliminary and final determinations are catalysts for the protected producers. It is narrower and more surgical than broad tariffs.
- Track record
- Antidumping orders on imported steel, solar, and chemical products have supported the domestic petitioners that filed the cases.
- Who it affects
- Domestic producers in petitioning industries: NUE, STLD, FSLR (per case).

- Common misread
- Cases are product- and country-specific; assuming a duty protects a whole sector overstates the reach.
- Watch out for
- Investigations run months and can end in negative determinations with no duties.
