CBP protest: how to challenge a US customs decision within 180 days

If US Customs and Border Protection (CBP) liquidates an entry with a higher duty, a different classification or value, or excludes goods, the importer can file a protest under 19 CFR Part 174 within 180 days. CBP must decide within 2 years, or within 30 days if accelerated disposition is requested, and a denied protest can be taken to the US Court of International Trade within 180 days.

What can be protested

Under 174.11, a protest can challenge the appraised value, the classification, rate and amount of duties, charges or exactions including interest, the exclusion of goods from entry or delivery or a demand for redelivery, the liquidation, reliquidation or modification of an entry, a refusal to pay a drawback claim, and certain refusals to reliquidate. Clerical errors and mistakes of fact adverse to the importer can also be protested.

Protests may be filed by the importer or consignee of record and their sureties, anyone paying a charge or receiving a refund, anyone seeking entry or delivery, drawback claimants, qualifying exporters or producers in certain origin decisions, and authorised agents.

What the protest must contain (174.13)

Review and next steps

The protest is filed on CBP Form 19, in quadruplicate, at the port of entry, or electronically through ACE, and it can be amended until the 180-day period ends. Several entries can be covered in one protest if they have the same protestant, merchandise category and decision. CBP must allow or deny the protest within 2 years; a party can request accelerated disposition by registered or certified mail, and the protest is deemed denied if CBP does not act within 30 days.

An application for further review can ask for review at a higher level, for example when the decision is inconsistent with a CBP ruling or raises unresolved questions of law or fact. If the protest is allowed, excess duties are refunded. If it is denied, the protestant can file a civil action in the US Court of International Trade within 180 days after the denial notice is mailed or after a deemed denial.

Step by step

  1. Check the liquidation date or decision date on the entry in ACE and calculate the 180-day deadline.
  2. Collect the evidence: commercial invoice, classification rulings, value documents or proof of the error.
  3. Prepare the protest with all 174.13 contents and specific objections.
  4. File it on CBP Form 19 at the port of entry or electronically in ACE, and consider an application for further review.
  5. If you need a quick answer, request accelerated disposition; if the protest is denied, decide within 180 days whether to go to the Court of International Trade.

Common problems and how to avoid them

The importer notices an overpayment 7 months after liquidation.

What to do: The 180-day protest period has passed; protest within 180 days of liquidation next time and track liquidation dates in ACE.

The protest only says the duty is wrong.

What to do: State distinct and specific objections with reasons, and describe the merchandise specifically.

CBP has not answered after months.

What to do: Request accelerated disposition by registered or certified mail; without action in 30 days the protest is deemed denied and can go to court.

A denied protest is left too long.

What to do: File in the Court of International Trade within 180 days after the denial notice is mailed.
