On August 3, 2026, in Cargo Systems Messaging Service (CSMS) # 69428352, U.S. Customs and Border Protection (CBP) announced important changes to the Post Summary Correction (PSC) process that will become effective August 5, 2026. These modifications were announced in the Federal Register Notice 91 FR 41053 issued July 6, 2026.
These changes primarily impact how duty increases resulting from PSCs are paid and expand filing flexibility for certain suspended entries. Additionally, CBP provides an overview of the ACH Debit and Credit payment process.
Key Takeaways
- Mandatory Electronic Payment for PSC Duty Increases
- Any increase in estimated duties, taxes, or fees resulting from a PSC must be paid electronically via ACH.
- CBP will no longer accept payment by check or cash for PSC-related increases.
- Greater Flexibility on Timing of PSC Payments
- Importers may:
- Pay the increased duties and fees before liquidation, or
- Wait until CBP issues a bill at liquidation.
- However, a subsequent PSC cannot be filed until any increase from a previously filed PSC has been paid in full and processed by CBP.
- Expanded PSC Filing Opportunities for Suspended Entries
- CBP is allowing PSCs to be filed beyond the standard 300-day filing window for entries whose liquidation remains suspended beyond 300 days.
- This applies to entries with qualifying suspension bases, including:
- Antidumping (AD)
- Countervailing (CVD)
- AD/CVD cases
- Enforce and Protect Act (EAPA) related suspensions
- Court injunctions
- Interest Payments Deferred Until Liquidation
- Interest related to PSC duty increases will not be accepted before liquidation.
- Any interest owed will be billed and collected after liquidation, if applicable.
Potential Impact for Importers
- Review ACH enrollment and payment processes to ensure compliance and timely payment before August 5, 2026.
- Monitor PSC filings carefully, as unpaid PSC increases could delay the ability to submit additional corrections.
- Companies with AD/CVD, EAPA, or other suspended entries may benefit from the expanded PSC filing flexibility.
