New ACE CATAIR Error F883: PSC Not Allowed to Modify IEEPA HTS
CBP has added Error F883 to the ACE CATAIR Error Dictionary, blocking Post Summary Corrections (PSCs) from modifying HTS numbers that fall under IEEPA tariff provisions. Filers attempting to change IEEPA-classified HTS numbers via PSC will now receive this hard error in ACE.
We are flagging this immediately for our filing teams — if an entry requires an HTS correction on IEEPA-covered goods, a PSC is no longer the path forward and we will need to evaluate protest or other corrective mechanisms. Verify classification accuracy on IEEPA entries before filing to avoid downstream correction problems.
