Antidumping and Countervailing Duties are duties designed to protect importers against overseas merchants “Dumping” their merchandise in the United States at unfair prices. The entries that are made under this section remain open until the ADD or CVD cases are closed. This can be many years before your potential liability is resolved. Please check with us to make sure your shipments are not subject to these duties. Or you can visit the Customs website at www.customs.gov and check yourself.
