Critical Deadlines: Entries typically liquidate at 314 days. Missing the 180-day protest deadline is an absolute bar to recovery.

Any pre-liquidation entry error — a wrong HTS classification, an undervalued shipment, a missed exemption, an overpaid tariff — can potentially be corrected through a PSC. The catch: the window is per-entry, and it doesn't wait for anyone.

What a Post Summary Correction Can Fix
A Post Summary Correction lets you amend a customs entry before it liquidates — fixing the kind of errors that cost real money if they go uncorrected. That includes a misclassified HTS code, an incorrect valuation, a missed trade-agreement or exemption claim, and overpaid duties under any tariff program, including IEEPA, the forced-labor Section 301 tariffs, the expired Section 122 surcharge, and antidumping/countervailing duty (AD/CVD) entries.
The catch doesn't change with the news cycle: you have to file before your entry liquidates, or the PSC option is gone for that entry — permanently. That's a standing rule, not a temporary one.

What entries qualify for PSC filing?
Any entry where duties, fees, or classifications need correction may qualify for a PSC. Entries that haven't liquidated can be amended through the PSC process.
How do I know if my entries have liquidated?
We can check liquidation status through ACE. Generally, entries liquidate 314 days after entry unless extended.
Can I file PSCs myself without a broker?
Yes, if you are a self filer. The PSC must be filed by a licensed customs broker or self-filed if you self-file your customs entries. If you self-filed the original entry, you can self-file your PSC. Otherwise your PSC must be filed by a licensed customs broker.
How long until I receive refunds?
CBP typically processes PSC-related refunds within 90-120 days. Processing times may vary depending on volume and complexity.
Which tariff overpayments can a PSC recover?
A PSC can correct duty overpayments from most tariff programs on an entry that hasn't liquidated yet — including IEEPA duties, the forced-labor Section 301 tariffs, and the expired Section 122 import surcharge, along with standard classification and valuation errors. Antidumping and countervailing duty (AD/CVD) entries follow additional rules, so those are worth a direct conversation with a broker. Learn more about the forced-labor Section 301 tariffs.
