Protests and post-entry: challenging a CBP decision (19 CFR Part 174)

Entry does not end at liquidation. Once CBP fixes the classification, value, or duty on an entry, the importer of record still has a formal path to disagree with that decision: the protest, governed by 19 CFR Part 174. This guide covers what can be protested, who may file, the filing window, the further-review and accelerated-disposition mechanics, and post-summary correction, the pre-liquidation alternative that heads off most disputes before a protest is ever needed. For where Part 174 sits among the others, see the corpus map; the glossary defines liquidation and entry summary.

What CBP decisions can be protested?

Section 174.11 lists the decisions a party may protest, and the exam draws directly from this list. The protestable decisions include:

• The appraised value of merchandise.
• The classification and rate and amount of duties chargeable.
• All charges or exactions of whatever character, including the accrual of interest.
• The exclusion of merchandise from entry or delivery under the customs laws.
• The liquidation or reliquidation of an entry, or any modification of an entry.
• The refusal to pay a claim for drawback.
• The refusal to reliquidate an entry.

Most of these share a common shape: CBP made a determination, that determination is now final unless timely challenged, and Part 174 is the mechanism for the challenge. Liquidation is the most-tested trigger because it is the point at which the entry’s duty becomes fixed, covered in the entry process guide.

Who may file a protest, and against whom does the clock run?

Under 174.12(a), the parties eligible to protest are the importer or consignee shown on the entry papers, or their sureties, along with anyone who has paid or is entitled to receive a refund of the charges in question, anyone seeking entry or delivery, a person filing a drawback claim, or the authorized agent of any of these. A surety may protest independently of the importer, which matters because a surety’s bond exposure runs with the entry regardless of what the importer chooses to do.

How long do you have to file a protest?

This is the single most-tested number in the category, and it is already the fastest lookup a candidate makes: under 19 USC 1514(c)(3) and 19 CFR 174.12(e), a protest against an entry made on or after December 18, 2004 must be filed within 180 days of the date of notice of liquidation or reliquidation, or the date of the decision being protested. For entries made before that date, the window is 90 days. The clock’s starting point depends on what is being protested:

Trigger event	What starts the clock
Liquidation or reliquidation	The date of notice of liquidation or reliquidation
A CBP decision not involving liquidation (an exaction, an exclusion)	The date of that decision
A demand for payment against a surety’s bond	The date the demand is mailed

Filing is complete only when the protest is actually received by the CBP officer with whom it is required to be filed, not when it is mailed. Miss the 180 days and the underlying decision becomes final, foreclosing the protest route entirely; a later post-summary correction cannot reach a liquidated entry either, so both remedies run out at the same wall.

What must a written protest contain?

Section 174.13 sets the required contents, and a protest missing them can be rejected as deficient. A protest must state:

• The name and address of the protestant, and of the protestant’s authorized agent or attorney if one is filing.
• The importer number of the protestant, and of the agent if applicable.
• The entry number, and the date of liquidation of the entry (or the date of the decision, for a decision not involving a liquidation).
• A specific description of the merchandise affected by the decision.
• The nature of, and the justification for, the objection, set forth distinctly and specifically for each category or decision protested.
• The date and number of any protest previously filed by the protestant that involves the same category of merchandise and issues, if any.

A single protest may cover multiple entries when they involve the same party, category of merchandise, and category of decision, which is why brokers batch entries with a common issue into one filing rather than filing separately for each.

What is further review, and when is it available?

An ordinary protest is decided at the port or Center level. Further review, requested under 174.25, escalates the decision to Headquarters and is available under 174.24 when the protested decision meets one of a specific set of criteria:

• It is alleged to be inconsistent with a ruling of the Commissioner of CBP, or with a decision CBP made on the same or substantially similar merchandise.
• It involves questions of law or fact that have not been ruled on by the Commissioner or by the Customs courts.
• It involves matters previously ruled on, but the protestant presents facts or legal arguments not previously considered.
• It involves questions that Headquarters previously refused to consider through a request for internal advice.

Further review exists for the cases where a single port’s answer is not good enough, either because it conflicts with an existing ruling or because nobody has ruled on the question yet. A protest that does not fit one of these criteria is decided locally and does not go to Headquarters.

What is accelerated disposition, and what happens if CBP does not act?

Accelerated disposition, under 174.22, is a request that flips the pressure back onto CBP. A protestant files a written request for accelerated disposition by registered or certified mail with the appropriate CBP officer. From the date that request is mailed, the Center director has 30 days to review the protest and allow or deny it, in whole or in part. If CBP does not act within that window, the protest is deemed denied at the close of the 30th day following the date of mailing.

That deemed denial is not a loss on the merits; it is a procedural device that lets a protestant stop waiting and move on to judicial review at the Court of International Trade rather than sit indefinitely on an unanswered protest. A protestant who wants a fast answer, or who wants to preserve the option to litigate promptly, uses accelerated disposition; a protestant content to wait for an ordinary decision does not need it.

What happens when a protest is denied?

Under 174.29, if the Center director denies a protest, in whole or in part, notice of the denial must be given in the form and manner prescribed by 174.30. A denial (including a deemed denial under accelerated disposition) is what opens the door to judicial review of the underlying decision; Part 174 itself governs only the administrative protest, not what happens in court afterward.

What is post-summary correction, and how is it different from a protest?

Post-summary correction (PSC) is the pre-liquidation counterpart to a protest. Where a protest challenges a decision CBP has already finalized at liquidation, a PSC is filed electronically before liquidation to correct an entry summary the importer or broker itself got wrong, a misclassification, an undervaluation, a wrong preference claim, before CBP ever fixes the final duty. The practical distinction to keep straight for the exam:

	Post-summary correction	Protest
Timing	Before liquidation	After liquidation (or another protestable decision)
Who is correcting what	The importer corrects its own entry summary	The importer challenges CBP’s decision
Governing framework	Filed through the entry summary process	19 CFR Part 174

A correction that never gets filed before liquidation does not disappear: once the entry liquidates, the importer’s only remaining path to fix the same error is a timely protest under Part 174, filed within the 180-day window above. That is the throughline of this whole guide: fix it before liquidation through the entry summary, or fix it after liquidation through a protest, and once both windows close the liquidated duty stands.

Practicing protests and post-entry for the exam

Protest questions reward knowing three numbers cold: the 180-day filing window, the 30-day accelerated-disposition deadline, and which of the four further-review criteria a fact pattern matches. Drill the lookups in the navigation trainer, place Part 174 among entry, valuation, and drawback in the corpus map, race the deadline citations in the citation race, and test recall with the free practice test. For the entry and liquidation mechanics that a protest challenges, see the guides on the entry process and recordkeeping; for the penalty track that runs alongside a disputed entry, see customs penalties and prior disclosure. The protest itself is filed on CBP Form 19, and every one of these deadlines is collected with its full trigger and cite on the key deadlines reference.
