The Customs Protest Under 19 U.S.C. § 1514: How California Importers Challenge a CBP Decision
After an entry liquidates, the protest is the importer’s formal challenge to CBP’s decision — and the gateway to the Court of International Trade. Miss the 180-day deadline and the decision becomes final.
When CBP liquidates an entry in a way the importer disputes — a reclassification, a higher value, a denied preference, an excess duty — the formal way to challenge it is a protest under 19 U.S.C. § 1514. The protest is both the administrative remedy and the mandatory gateway to the Court of Internat
A liquidation the importer disagrees with is not the end of the road — but the road runs through a protest. Section 1514 of the Tariff Act sets out what can be protested, how, and by when, and it is the mandatory first step before most customs litigation.
What Can Be Protested
19 U.S.C. § 1514 makes CBP decisions on a range of entry matters “final and conclusive” unless protested — which means the protest is how you preserve a challenge. Protestable decisions include the appraised value of merchandise, the classification and rate of duty, charges and exactions, the liquidation or reliquidation of an entry, and the denial of certain claims. If a decision is protestable and no protest is filed, it becomes final.
The 180-Day Deadline
A protest must be filed within 180 days after the date of liquidation (or the date of the decision being protested). This deadline is strict. Because liquidation typically occurs about a year after entry, importers must track liquidation dates and calendar the 180-day protest window, or they lose the right to challenge and to sue.
Further Review and Accelerated Disposition
- Application for Further Review (AFR). A protest may request further review, which sends the legal question to a higher CBP office (or Headquarters) rather than being decided solely at the port — useful where the issue involves a novel or important question of law.
- Accelerated disposition. A protesting party can request accelerated disposition; if CBP does not act within the statutory period after such a request, the protest is deemed denied, which lets the importer move promptly to court rather than waiting indefinitely.
The Path to the Court of International Trade
If CBP denies the protest, the importer may bring the dispute to the U.S. Court of International Trade under 28 U.S.C. § 1581(a), generally within 180 days of the denial, and typically must have paid the liquidated duties to invoke the court’s jurisdiction. The CIT reviews the matter on a fresh record. Because the protest defines the decisions and issues that can be litigated, a well-framed protest is the foundation of a successful CIT case.
Protest vs. Post-Summary Correction vs. Prior Disclosure
The protest is the after-liquidation remedy. Before liquidation, a Post-Summary Correction fixes a known error. Where the issue is a potential penalty violation (a material false statement), a prior disclosure under § 1592(c)(4) is the tool that limits exposure. Choosing the right mechanism for the posture of the entry is essential.
