An anti-dumping duty is an extra tariff imposed on imports after authorities conclude that the imports are dumped under the legal definition and that they injure a domestic industry.
How the duty is set
The duty is usually tied to the estimated dumping margin, which is the gap between the export price and a benchmark “normal value” defined by trade rules. The result can be an ad valorem tariff or a specific per-unit duty.
Economic trade-offs
An anti-dumping duty can raise the price of imported goods and give domestic producers breathing room. But it can also:
- raise costs for consumers,
- harm downstream firms that use the imports as inputs,
- invite lobbying and protection-seeking,
- weaken the gains from trade.
Why the distinction matters
Anti-dumping duties are not the same as countervailing duties or safeguards. Each tool responds to a different policy problem, even though all of them restrict trade.
