Key Takeaways
- A Post Summary Correction fixes entry errors before liquidation. Filed through ACE, a PSC is the electronic successor to the Post Entry Amendment and the only way to correct an accepted entry summary while the entry is still open.
- Corrections can put money back in the importer’s pocket. When a change reduces the duties, taxes, or fees owed, such as a classification or valuation error, CBP refunds the difference.
- The entry has to qualify. Most formal entry types are eligible, informal entries are not, and the entry summary must be accepted, fully paid, unliquidated, and not under CBP review.
- Complete documentation drives the refund. CBP expects current data and supporting records, including the commercial invoice, entry and line numbers, and the corrected refund amount.
A Post Summary Correction is an enhanced and digitally enabled version for the Post Entry Amendment introduced by U.S. Customs and Border Protection. This system is deployed under the ACE or Automated Commercial Environment.
To get the refund from the government the importers need to submit PSC for the ACE type 1,2,3,6,7,21,22,23,31,32,34,38,51, and 52. Here, the informal Type 11 and informal & quota Type 12 entries are not eligible for the PSC refund.
Criteria for a Post Summary Correction Refund
The U.S. Customs and Border Protection have set up few criterion’s so that importers or brokers can get a refund for the fee paid under PSC. Below are some of the criterion’s for the previously filed PSC or the original entry summary:
- The “entry summary” must be paid fully or it must be revenue free. The periodic monthly installments that are included must be up to 45 days.
- The commercial invoice sent by the vendor to the importer is used for the refund process.
- This summary is not in liquidated position.
- The Post Summary Correction must be filed within 300 days of the date of entry and at least 15 days before the scheduled liquidation date, whichever comes first. If CBP has approved an extension of liquidation, the 300-day limit doesn’t apply, but the 15-day cutoff still does.
- The summary must not be under the CBP review. Here the importer will receive information that “Post Summary Correction-not allowed under the CBP review.” This message is flashed when the PSC is under the review of Customs and Border Protection.
- Once the PSC window closes, ACE rejects the correction, and the fix has to wait until the entry liquidates and then go through a protest.
- If there is any inaccuracy seen by the importer, it must be immediately reported to the CBP so that there is no hindrance in then claiming process. There is a declaration done in the CBP Form 7501 that states that all the information about the selling of the goods and their costs are disclosed by the importer.
Other Data Required for a PSC Refund
The PSC filer must be the original filer of the entry summary who possesses the invoices of the products. The ACE must identify the real filer for the communication process regarding the refunds. It must include any further information from the importer’s side too. Here are some of the additional pointers if you are looking for a refund:
- The data provided by the importer must be up-to-date.
- If there are any monetary changes done in the invoices, then they must be initiated while filling the PSC.
- Before providing a refund to the importer or the broker, CBP will track all the submissions done by the importer.
- One cannot make quarterly submissions of the ACE Entry summaries.
- There should not be any reconciliation from the importer’s side about the PSC summary.
- To get the claim, one must file information as Entry number, Line number, total refund value, signed statements or invoices, and personal details like Name, Contact Number, and E-mail address of the importer or the broker.
Can You Use a Post Summary Correction for IEEPA Tariff Refunds?
No. After the Supreme Court struck down the IEEPA tariffs on February 20, 2026, CBP built a separate refund process called CAPE inside ACE, and it has told importers not to file PSCs to request IEEPA refunds. PSCs are still the right tool for other corrections, like classification or valuation errors, and those should be filed before an entry goes on a CAPE declaration, since an entry accepted into CAPE can no longer take a PSC.
If those same entries also carry Section 301 or other duties on goods you later export, that part may be recoverable through duty drawback. Our breakdown of IEEPA refunds vs. duty drawback walks through how the two interact on the same entry.

Frequently Asked Questions
Most entry summary data can be corrected, including tariff classification, valuation, quantity, and country of origin. Both revenue changes, which affect the duties owed, and non-revenue changes are allowed. A few fields are off limits, such as the importer of record and the date of entry, which follow separate processes.
Yes. When duties were overpaid because of a classification or valuation error, or a retroactive exclusion now applies, a PSC on an unliquidated entry is the standard way to claim the refund. Identifying which entries are still open is the first step, since the option disappears at liquidation.
The refund is issued once CBP accepts the correction and the entry liquidates with the change. Filers can request accelerated liquidation to speed that up, and CBP asks filers to allow up to 90 days on those requests before checking status. Timing varies with where the entry sits in the liquidation cycle.
There is no limit on the number of PSCs while the filing window is open. Each new PSC replaces the full entry summary, so it must include all required data. The exception is an entry under CBP team review, which allows only a single PSC.
A PSC is no longer an option once an entry liquidates. At that point, the correction path is a protest, which must be filed within 180 days of the liquidation date. Where an error involves a potential violation, a prior disclosure may be the more appropriate route.
A PSC corrects errors on the import entry itself, refunding duties that should not have been paid in the first place. Duty drawback refunds duties that were correctly paid on goods later exported or destroyed. Many importers use both, and CITTA can evaluate which applies to a given entry.
