Importers using Post-Summary Corrections (PSCs) should be aware of an upcoming operational change. Beginning August 5, 2026, U.S. Customs and Border Protection (CBP) will implement updates to the Post-Summary Correction process under the National Customs Automation Program (NCAP) test.
What Is a Post-Summary Correction?
A Post-Summary Correction allows importers to correct certain information on an entry after it has been filed, but before liquidation. PSCs are commonly used to amend details such as classification, value, origin, or other entry data when errors are identified after the entry summary has been submitted.
What’s Changing?
The updated NCAP test refines how PSCs are processed in ACE and clarifies filing requirements and system validations. While the changes are primarily operational, importers who regularly submit PSCs should ensure their internal processes and software are aligned with the updated requirements.
For many importers working with a customs broker, these changes will be handled as part of the brokerage filing process. Companies that self-file or routinely submit PSCs directly through ACE should review the updated guidance before filing corrections.
What Importers Should Do
- Review the updated PSC requirements with your customs broker or compliance team.
- Confirm your ACE filing procedures reflect the new system validations.
- Continue identifying and correcting eligible entry errors before liquidation whenever appropriate.
While these updates may not significantly change day-to-day operations for every importer, understanding the revised PSC process can help avoid filing issues and support smoother customs compliance.
