CBP barred PSC changes to IEEPA HTS on FTZ entry type 06
CBP announced an update to the ACE CATAIR Error Dictionary adding a new validation, error F883, that blocks a Post Summary Correction from modifying the IEEPA HTS on a Foreign Trade Zone entry type 06. CBP deployed the change to its certification and production systems on August 21, 2026. The update affects filers submitting PSCs on FTZ entries with an IEEPA HTS line.

This update applies to Foreign Trade Zone entry type 06 filings, and Allied does not operate or manage foreign trade zones. We do not expect this validation to affect the entries we file for clients. Because IEEPA duties themselves ended on February 20, 2026, clients with questions about how this rule applies to their entries should ask Allied to review the specific filing.
CBP added new ACE error to block conflicting duty status on auto parts and heavy vehicle HTS lines
CBP announced an update to the ACE CATAIR Error Dictionary that added a new fatal error, F876. The error stops an entry summary line from having both a dutiable Auto Part HTS number and a dutiable Medium and Heavy-Duty Vehicles HTS number in Chapter 99 at the same time. CBP deployed this validation to the certification and production ACE environments on June 25, 2026. The change affects filers who submit entry summaries with both types of HTS numbers on one line.

This was a system-level filing rule for entry summaries with combined Auto Part and MHDV Chapter 99 HTS numbers. It appears to remain in effect, since we have not seen a later CSMS message that changes it. If you import auto parts or medium and heavy-duty vehicles, ask us to review how your entries classify Chapter 99 duty status on these lines.
CBP added duty checks in ACE for entries with up to 32 HTS codes per line
CBP announced that on February 17, 2026 it deployed an ACE enhancement that validates filer-provided duty amounts on entry summary lines listing up to 32 HTS codes. When a filer's duty amount does not match CBP's calculation, ACE returns condition code 624 for a line mismatch or 627 for a total mismatch. The message directed technical questions to CBP client representatives and other questions to CBP's ESAR email address.

This is a system level change to how CBP validates entry summary duty amounts, and it concerns the filing process rather than importer action. We account for these mismatch codes when we prepare and transmit entry summaries with multiple HTS codes per line. Clients do not need to do anything because of this message, but if a specific entry shows a duty discrepancy, clients should ask us to review it.
