Protest Denied CIT: The 180-Day Road to Court of International Trade

Key Points
- A denied CBP protest opens a 180-day window to commence a civil action at the Court of International Trade (CIT) by summons, under 28 U.S.C. 2636(a).
- Jurisdiction at the CIT is grounded in 28 U.S.C. 1581(a), which gives the court exclusive jurisdiction over civil actions contesting CBP decisions on denied protests.
- All liquidated duties, charges, or exactions covered by the protest must be paid in full before the action is commenced, per 28 U.S.C. 2637(a); failure to pay is a jurisdictional defect.
- If CBP has not acted on a protest within 30 days of filing, the importer may request accelerated disposition under 19 CFR 174.22; after 90 days of inaction following that request, the protest is deemed denied by operation of law.
- The 180-day deadline is firm: missing it forfeits the right to CIT review of that protest, and no administrative appeal within CBP remains available after denial.

When CBP denies a protest, the importer's only remaining avenue for relief is a civil action at the Court of International Trade, commenced by summons within 180 days of the denial. Missing that deadline or failing to pay all liquidated duties first will eliminate the claim entirely. The sections below walk through every step of that path, from the moment of denial to the opening of a CIT docket.

What a denied protest means and why it matters
A CBP protest is the administrative mechanism an importer uses to challenge a CBP decision made on a liquidated entry, including the classification, valuation, rate of duty, or applicability of a special measure such as a Section 301 or Section 232 tariff. If you are contesting duties on goods covered by provisions like Section 301 List 4 or Section 232 UAS tariffs, a protest is often the first step in a formal duty-recovery sequence.
CBP may deny a protest expressly, by issuing a written denial decision, or constructively, by taking no action within certain statutory timeframes (discussed below). Either way, the denial closes the administrative record at CBP. There is no internal appeals tier within CBP above the protest level. The only path forward is federal court.
Jurisdiction and the statutory framework
The Court of International Trade has exclusive subject-matter jurisdiction over civil actions arising from denied protests. That grant of jurisdiction is set out in 28 U.S.C. 1581(a), which covers actions contesting a denial of a protest filed under the customs laws.
The deadline and commencement mechanism are in 28 U.S.C. 2636(a). That statute provides that a civil action must be commenced by filing a summons at the CIT within 180 days of the denial of the protest. The summons, not a complaint, is the document that starts the clock on the court side and preserves the claim.
The CIT is an Article III federal court. Its decisions are appealable to the United States Court of Appeals for the Federal Circuit and, ultimately, to the Supreme Court. Practically speaking, most denied-protest litigation resolves before a merits trial, through motions practice or settlement.
The 180-day deadline: how it is triggered and counted
The 180-day period runs from the date of denial. For an express denial, CBP issues a formal decision under 19 CFR 174.31, and the clock starts on that date. For a constructive denial arising from accelerated disposition (see below), the date of deemed denial starts the 180-day count.
Calendar counting, not business days
The 180-day period is a calendar-day count. Importers and their counsel should docket the deadline the same day the denial is received and should not assume any tolling for holidays, weekends, or mail-delivery delays. If day 180 falls on a weekend or federal holiday, practitioners routinely file before that date rather than relying on any extension rule, because the statute itself is not tolled by court rule in the ordinary way.
What must be filed
The summons is filed with the clerk of the CIT. It identifies the protest number, the entry or entries at issue, the amount in controversy, and the basis of the claim. A complaint is filed later, on a schedule set by the court's rules, and lays out the legal theory in full. The summons alone is what preserves the claim within the 180-day window.
The payment-first requirement under 28 U.S.C. 2637(a)
28 U.S.C. 2637(a) conditions CIT jurisdiction on the prior payment of all liquidated duties, charges, or exactions that are the subject of the action. This is a pay-to-play rule: an importer cannot ask the court to order a refund of duties that have not yet been paid.
In practice this means that if entries were protested but duties remained unpaid or only partially paid, the importer must cure the payment deficiency before commencing the action or risk dismissal for lack of jurisdiction. Customs bonds satisfy the payment requirement in some circumstances, but the analysis of whether bond obligations meet the statutory standard is fact-specific. Importers should verify their payment status for every entry covered by the protest before the summons is filed.
Importantly, the payment requirement applies to the liquidated amounts, not to the amounts the importer believes are correct. If an entry was liquidated at a higher duty rate and the importer disagrees, the full liquidated amount must still be paid before the CIT can hear the case.
Accelerated disposition: forcing a denial after 90 days
CBP does not always act on protests promptly. Under 19 CFR 174.22, if CBP has not allowed or denied a protest within 30 days of its filing, the importer may file a request for accelerated disposition. Once that request is filed, if CBP takes no action within 90 days, the protest is deemed denied by operation of law.
This constructive denial then triggers the 180-day window under 28 U.S.C. 2636(a) just as an express denial would. Accelerated disposition is a strategic tool: it lets the importer control timing instead of waiting indefinitely for CBP to act, and it can be useful when entries are aging toward expiration of other procedural rights or when market conditions favor resolving the dispute quickly.
The tradeoff is that requesting accelerated disposition forecloses the possibility that CBP would have allowed the protest on its own. Importers should weigh the likelihood of an administrative allowance against the value of moving to court sooner.
Posture of the case at the CIT
Once the summons is filed and the complaint follows, the CIT reviews the CBP determination on the administrative record that was developed at the protest stage. The court applies the standard of review appropriate to the legal question at issue: for classification disputes, the court reviews legal questions of tariff interpretation without deference to CBP's position, while factual findings underlying classification receive a more deferential standard. For valuation and other mixed questions, the analysis varies.
The importer bears the burden of showing that the CBP determination was incorrect. That burden does not shift until the importer presents a prima facie case. The government, represented by the Department of Justice's Civil Division (Trade Section), defends CBP's decision. Discovery, motions for summary judgment, and occasionally trial on stipulated facts are all part of the CIT's procedural toolkit.
Refunds, if the importer prevails, include the excess duties paid plus interest calculated from the date of payment. The interest rate is set by statute and is applied automatically when a judgment is entered in the importer's favor.
What importers should do
- Calendar the 180-day deadline immediately. The moment a protest denial arrives, record the deadline date in your compliance system. Do not rely on memory or informal tracking. Missing day 180 is a permanent, unrecoverable loss of the claim.
- Verify that all liquidated duties are paid before filing the summons. Pull the liquidation notices and payment records for every entry covered by the protest and confirm full payment under 28 U.S.C. 2637(a). Partial payment will not satisfy the jurisdictional requirement.
- Evaluate accelerated disposition as a proactive tool. If a protest has been pending more than 30 days without action, review 19 CFR 174.22 and consider whether requesting accelerated disposition serves your timeline and litigation strategy.
- Retain trade counsel before the summons deadline. The CIT's rules and the substantive law of customs classification, valuation, and special tariff measures are specialized. Engage counsel with CIT experience early enough to prepare the summons and map a complaint strategy well before the deadline.
