On July 5, 2018, U.S. Customs and Border Protection (CBP) published guidelines for identifying third country antidumping and countervailing duty (AD/CVD) case numbers in the Automated Commercial Environment (ACE) system.
According to CBP, the AD/CVD orders “generally cover products from the country identified in the AD/CVD order,” and that some merchandise produced in the country of the AD/CVD order may undergo further processing in a third country and still remain subject to the AD/CVD order. CBP has created third country case numbers to allow importers to report such shipments.
The guidelines state that the third-country case name and short description in ACE are the same as the case name and short description of the AD/CVD order, and will have a reference to the country of the AD/CVD order at the end.
CBP directs any questions on third country AD/CVD case numbers in ACE to the U.S. Department of Commerce at 202-482-0984.
