Frequently Asked Questions

What can a Post Summary Correction fix?

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.

Can a PSC recover tariff overpayments?

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.

How long does it take to receive a PSC refund?

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.

How many PSCs can be filed on the same entry?

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.

What happens if the entry has already liquidated?

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.

How is a PSC different from duty drawback?

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.
