Priority Trade Issue: Antidumping and Countervailing Duties

When the Department of Commerce finds that imported merchandise was sold in the U.S. at an unfairly low or subsidized price, to level the playing field for U.S. companies injured by these unfair trade practices, CBP is responsible for collecting the Antidumping and Countervailing Duties (AD/CVD) in a timely manner.

The goal of this AD/CVD Priority Trade Issue is to detect and deter circumvention of the AD/CVD law, to liquidate final duties timely and accurately, while at the same time facilitating legitimate trade.
