What Is a CBP Protest and How Do You File One?

What Is a CBP Protest?

A CBP Protest (formally, a protest filed under 19 U.S.C. § 1514) is the primary legal mechanism for challenging U.S. Customs and Border Protection decisions after an entry has been liquidated. Liquidation is the final assessment of duties owed, and once it occurs, the protest process is your main avenue for recovering overpaid amounts.

Protests can challenge CBP decisions on:

The 90-Day Filing Window

This is the most critical deadline in customs law. Protests must be filed within 90 days of the date of liquidation. Missing this deadline is typically fatal to your claim — CBP cannot accept late protests, and there are very limited exceptions.

To find your liquidation date:

1. Log into the ACE portal (Automated Commercial Environment)

2. Review your entry summary for the "Liquidation Date" field

3. Check CBP Bulletin Notices of Liquidation (published weekly)

Who Can File a Protest?

Any party with a financial interest in the imported merchandise can file a protest, including:

Most importers work with a licensed customs attorney or customs broker to prepare and file protests, as the technical requirements and legal arguments require expertise.

The Protest Process

Step 1: Identify the Issue

The first step is a thorough review of your entry summary (CBP Form 7501), the HTS classification used, and the duty rate applied. Compare the actual classification to the appropriate classification under the Harmonized Tariff Schedule of the United States (HTSUS).

Step 2: Prepare Legal Arguments

A strong protest includes a clear statement of the claimed error, supporting legal authority (CBP rulings, court decisions, the HTSUS General Rules of Interpretation), and product information (specifications, manufacturing processes, intended use).

Step 3: File via ACE

Protests are filed electronically through the ACE portal using CBP Form 19. The protest must specify:

Step 4: CBP Review

CBP has 30 days to issue a decision on most protests. Complex cases involving significant sums may be referred to CBP Headquarters (Office of Trade, Regulations and Rulings) for review.

Step 5: Further Appeal Options

If CBP denies your protest, you may file a Summons with the U.S. Court of International Trade (CIT) within 180 days of protest denial. This is where formal tariff litigation begins.

How Much Can You Recover?

The recoverable amount depends on:

For importers with high-volume entry programs, HTS misclassification protests routinely recover six and seven-figure amounts.

Working with a Customs Attorney

While importers can technically file protests themselves, the complexity of HTS classification law, CBP rulings, and procedural requirements makes attorney representation strongly advisable. Customs attorneys can:
