Found an entry error after filing?
A post-summary correction is an ACE process for changing eligible entry-summary data before liquidation within the applicable time rules. It is not available for every entry or every situation.
The four-step journey
Understand the purpose of a post-summary correction, eligibility, timing, supported changes, duty impact, review, and liquidation.
- An error or new fact is identified
- Eligibility and deadline are checked
- Corrected data and payment impact are filed
- CBP review and liquidation are monitored
What the broker checks
- Entry type, status, and liquidation date
- Reason, evidence, and affected lines
- Additional duty, refund implications, and client approval
Why it matters
Corrections work best when the system can trace the new value back to evidence and the original decision.
- PSC: Post-summary correction.
- Liquidation: CBP’s final duty determination for the entry.
