Antidumping and countervailing duties: every CBP message
Antidumping duties offset imports sold in the U.S. below fair value; countervailing duties offset foreign government subsidies. The Commerce Department sets the rates and the International Trade Commission decides whether a U.S. industry is injured. CBP collects the cash deposits at entry and liquidates entries on Commerce’s instructions.
CBP’s CSMS messages on AD/CVD cover filing changes in ACE, case updates, cash deposits and enforcement.
