Customs Recovery: 4 Ways to Get Overpaid Duty Back and Deadlines

Key Points
- Before liquidation, fix an overpayment with a post summary correction in ACE, filed within 300 days of entry and no later than 15 days before the scheduled liquidation date.
- After liquidation, file a protest under 19 U.S.C. 1514 within 180 days of liquidation.
- For exported or destroyed goods, duty drawback under 19 U.S.C. 1313 returns 99 percent of duties, and the claim window runs five years from import.
- Duties deposited under the terminated IEEPA headings are recovered through CBP's CAPE process, not through a protest or a post summary correction as the first step.
- The right route depends on where the entry sits in its lifecycle and what happened to the goods, so check liquidation status before anything else.

An importer gets overpaid duty back through one of four routes: a post summary correction before liquidation, a protest after liquidation, duty drawback when the goods leave the U.S. or are destroyed, or the CAPE refund process for IEEPA duties. Each route has its own clock, so the first step is to identify the entry's liquidation status and the cause of the overpayment.
Post summary correction: overpayment before liquidation
What it recovers and the clock
A post summary correction (PSC) amends the entry summary data in ACE, such as classification, value, country of origin, or a duty program claim, so the duty owed is recalculated. If the correction lowers duty, the importer gets the difference back through the normal refund of an overpayment on that entry.
- Deadline: within 300 days of the entry date, and no later than 15 days before the scheduled liquidation date. Whichever comes first controls.
- Who files: the importer of record or its licensed customs broker, electronically in ACE.
- Records needed: the original entry summary, commercial invoice, proof supporting the corrected data (classification analysis, valuation documents, origin evidence), and any program eligibility documents.
Because the second limit depends on the scheduled liquidation date, check that date in ACE rather than counting only from entry. Where an entry is flagged for reconciliation, see ACE reconciliation: Entry Type 09 flags, deadlines and filing for how that process differs.
Protest: overpayment after liquidation
What it recovers and the clock
Once an entry liquidates, the PSC route is closed. A protest under 19 U.S.C. 1514 challenges certain CBP decisions, including the liquidation itself, and asks CBP to reliquidate with a lower duty and refund the difference.
- Deadline: within 180 days of liquidation. Missing it generally makes the liquidation final.
- Who files: the importer of record, a broker with authority, or another party the statute allows to protest.
- Records needed: the entry and liquidation information, a clear statement of the decision protested and the grounds, and supporting documents such as invoices, classification rationale, and origin or valuation evidence.
The practical steps in ACE are covered in ACE Protest Module: Filing and Tracking CBP Protests Explained. Calendar the 180 days from the liquidation date shown in ACE, not from the date you noticed the problem.
Duty drawback: exported or destroyed goods
What it recovers and the clock
Drawback under 19 U.S.C. 1313 refunds 99 percent of duties paid on imported goods that are later exported or destroyed under the program's conditions. Unlike the other routes, nothing was necessarily overpaid in error. The duty was properly owed, and drawback returns it because the goods did not stay in U.S. commerce.
- Deadline: five years from the date of import.
- Who files: the drawback claimant, which may be the importer, the exporter, or a party holding the right through an assignment. Confirm who holds the right before filing.
- Records needed: import entry records showing duties paid, proof of export or destruction, and records linking the imported goods to what was exported or destroyed, whether by identical or substituted goods under the rules.
Export classification matters when building the linkage. For help with that side, see Schedule B Lookup: Find Your Export Code and When HTS Works. Records tying imports to exports are the most common weak point, so keep them from the day goods arrive.
IEEPA refund through CAPE
What it recovers and the clock
Duties deposited under the terminated IEEPA headings are recovered through CBP's CAPE process. This route exists because of the specific termination of those headings, so it works differently from a routine correction or protest. Entry status, liquidated or unliquidated, still affects how an importer should prepare.
- Deadline: follow the timing in CBP's CAPE instructions and in our IEEPA tariff refund guide. Do not assume the PSC or protest clocks are the only ones that matter.
- Who files: the importer of record, or a broker acting for it, through the CAPE process.
- Records needed: entry numbers, proof that duties were deposited under the IEEPA headings, payment records, and a reconciled list of affected entries.
For background on the headings themselves, read Reciprocal Tariffs Explained: IEEPA Duties, End Date, Refunds. Check the CBP website for current CAPE instructions.
Decision guide: which route fits your situation
- Overpaid, entry not yet liquidated: file a PSC, within 300 days of entry and at least 15 days before the scheduled liquidation date.
- Overpaid, entry already liquidated: file a protest within 180 days of liquidation.
- Goods exported or destroyed: file for drawback within five years of import, recovering 99 percent of duties.
- Duty deposited under a terminated IEEPA heading: use the CAPE process.
Routes can overlap. An IEEPA entry may also have an unrelated classification error, and exported goods may carry duty that was overpaid. Work each issue on the route and clock that fits it, and do not let a longer window on one route hide a short window on another.
What importers should do
- Pull a list of entries with their entry dates, scheduled liquidation dates, and liquidation dates, and calendar the PSC cutoff and the 180-day protest deadline for each.
- Tag entries with IEEPA duties and assemble payment and entry records for the CAPE process.
- Link import and export records at the time of shipment so drawback claims within the five-year window are supportable.
- Confirm which party holds the filing right (importer, broker, exporter, or assignee) before any deadline gets close.
