CBP updated the ACE CATAIR Error Dictionary V52 with validation error F883, preventing filers from submitting a Post Summary Correction for Foreign Trade Zone entry type 06 when an IEEPA HTS is modified.

This is an ACE filing-system measure, not a new duty rate by itself. CBP updated the ACE CATAIR Error Dictionary, which documents validation rules and error messages used when trade filers submit electronic entries and corrections. Validation error F883 concerns a Post Summary Correction (PSC) for a Foreign-Trade Zone (FTZ) entry type 06 when an IEEPA-related HTSUS classification is changed.

In practical terms, an importer or customs broker may be prevented from submitting that particular correction electronically until the filing is handled in a way that satisfies CBP’s rule. IEEPA refers to the International Emergency Economic Powers Act, which can authorize trade measures implemented through HTSUS provisions. The issue typically affects importers using FTZ procedures, entry type 06, and ACE PSC filings—not every importer subject to an IEEPA measure. The broker or authorized filer should review the entry history, classification, and CBP instructions before choosing a correction method.

What to check

• Confirm whether the transaction involves an FTZ entry type 06 and an HTSUS number subject to an IEEPA-related measure.
• Compare the original entry summary with the proposed PSC, including the HTSUS classification, quantities, value, and any required Chapter 99 or other reporting elements.
• Read the current ACE CATAIR Error Dictionary and related CBP guidance for validation error F883 before resubmitting the correction.
• Ask the customs broker or filing specialist whether the change requires a different correction process or supporting documentation.
• Verify that the final filing reflects the correct classification and applicable trade-measure reporting, and retain records explaining the change.
