CBP recently stated that by April 2nd importers must correct entries, with required antidumping (ADD) and countervailing duties (CVD) for missing third country ADD/CVD cases where the CBP and Commerce origin and scope tests yield two different countries. Because CBP’s ACE filing system did not allow importers to file the case numbers for over one year, and in many cases importers may not have known to request such a case number, importers should carefully weigh their options before presenting these late deposits to CBP.
