Customs & Tariff Classification
Liquidation
Also known as: Entry Liquidation
Liquidation is the final step in the customs entry process, the point at which the customs authority reviews the importer's declaration and makes its conclusive assessment of the duties, taxes, and fees owed on a shipment. Until an entry liquidates it remains open and subject to adjustment; once it liquidates, the calculated amount becomes final unless a timely protest is filed. Liquidation may confirm the amounts the importer originally deposited, or it may result in a refund or an additional bill, and in trade-remedy cases entries can be suspended from liquidation for years while dumping or subsidy rates are recalculated.
Delivery is not the end. The entry stays open until CBP liquidates it, and until then the duty figure is provisional. Importers who assume the file closed when the truck arrived are the ones surprised by a bill months later.
Where it matters for compliance
- Liquidation is CBP's final computation of duties on an entry. Deadlines for protest run from that date.
- Keep the file well past liquidation. The five-year retention runs from the date of entry — 19 CFR § 163.4 — and liquidation normally falls inside that window, not after it.
