Protests

CBP liquidated your entry.
You disagree. Good.

A Protest under 19 USC 1514 is the formal mechanism for challenging a CBP liquidation decision: a rate advance, a denied claim, a classification ruling, or any other adverse determination made at or after liquidation. You have 180 days from the date of liquidation to file. After that, the decision is final.

Caspian prepares and files CBP Protests on behalf of importers. Our licensed customs brokers and trade advisors know the arguments, the documentation standards, and the CBP review process. We build the case. We file the Protest. We track the outcome.

The Details

What Is a CBP Protest?

When US Customs and Border Protection liquidates a customs entry, it makes a final determination on classification, valuation, duty rate, and admissibility. If that determination results in an adverse outcome, including higher duties than you believe are owed, a denied drawback claim, or an incorrect rate application, a Protest is the statutory remedy.

Under 19 USC 1514, importers can file a Protest on Form CF-19 within 180 days of the date of liquidation. The Protest formally contests CBP's determination and requests reconsideration. CBP's Center of Excellence and Expertise (CEE) reviews the Protest and either grants or denies it. If denied, the importer can escalate to the Court of International Trade (CIT).

The Protest process is formal, technical, and deadline-driven. Missing the 180-day window is permanent and irreversible. Caspian monitors your liquidation calendar and flags protest-eligible entries before the clock runs out.

What Can Be Protested?

Classification Decisions
Expandable icon for frequently asked question section

CBP's determination of your HTS classification is protestable if the agency applied the General Rules of Interpretation (GRI) incorrectly, used a ruling that doesn't apply to your merchandise, or failed to give appropriate weight to the Explanatory Notes or prior CBP binding rulings. HTS classification protests are among the most common and highest-value protest types.

Rate Advances
Expandable icon for frequently asked question section

A rate advance occurs when CBP liquidates an entry at a higher duty rate than was declared on the entry summary. This is often the result of a CBP audit finding or a reclassification decision. Rate advances can represent significant unexpected duty liability. A Protest challenges whether the advance was legally and factually supported.

Denied Drawback Claims
Expandable icon for frequently asked question section

If CBP denies a duty drawback claim at liquidation or liquidates it at a lower amount than claimed, the importer can Protest the denial. Caspian files both the original drawback claim and, when necessary, the Protest of any adverse drawback liquidation decision.

Valuation Determinations
Expandable icon for frequently asked question section

CBP's rejection of a transaction value or first sale valuation claim, or the application of an alternative customs valuation method, is protestable. Valuation protests require detailed documentation of the buyer-seller relationship, price actually paid, and statutory additions and deductions under 19 USC 1401a.

Admissibility and Marking

Country of origin marking requirements, admissibility determinations, and certain exclusion orders can also be protested. These protests often intersect with Section 232, Section 301, and IEEPA tariff exclusion eligibility.

The Process

How Caspian Files Your CBP Protest

01

Identify

Caspian's platform monitors your CBP liquidation notices and cross-references them against your filed entries to identify adverse liquidation decisions, rate advances, and denied drawback claims that qualify for a Protest. Every protestable entry is flagged with the 180-day deadline and a preliminary recovery estimate.

02

Build the Case

Caspian's trade advisors and licensed customs brokers analyze the legal and factual basis for the Protest. They review CBP binding rulings, court precedents, GRI classification principles, and valuation statutory standards, then build the argument, assemble the documentation, and don't file until the case is airtight.

03

File

Caspian prepares and files the CF-19 Protest form directly with CBP's Center of Excellence and Expertise (CEE), including all supporting documentation, legal arguments, and supplemental evidence. Every Protest is filed on Caspian's own CBP-approved infrastructure.

04

Track and Escalate

Caspian monitors every Protest submission through CBP's review process, tracking status, responding to CBP requests for additional information, and advising on escalation to the Court of International Trade (CIT) if the Protest is denied and the recovery amount warrants further action.

Which Do You Need?

Protests vs. Post-Summary Corrections

Both Protests and Post-Summary Corrections (PSCs) recover duties, but they operate at different points in the CBP timeline. Caspian files both. The goal is to catch errors at the PSC stage. When that window has passed, we move to Protest. You don't need to know which applies. Caspian's platform monitors your entry timeline and routes each recovery opportunity to the right mechanism automatically.

PROTEST

A Protest is filed after liquidation, when CBP has made an adverse final determination. It's the correct tool when a PSC is no longer available or when CBP's decision itself is what's being challenged.

PSC

A PSC is filed before liquidation. It's faster, less formal, and typically the higher-success path. If an error can be corrected before CBP liquidates the entry, that's where Caspian starts.

Frequently Asked Questions

What is a CBP Protest?
Expandable icon for frequently asked question section

A Protest is a formal challenge to a Customs decision on an entry after it has liquidated. Filed under 19 USC §1514, a Protest is how importers contest adverse classification rulings, rate advances, denied claims, and other CBP determinations that resulted in higher duty owed. If CBP made a call you disagree with and the entry has already liquidated, a Protest is the mechanism that fights it.

How long do I have to file a Protest?
Expandable icon for frequently asked question section

180 days from the date of liquidation.  The window is statutory and non-negotiable. Once it closes, the CBP decision stands. Caspian's Trade Audit flags every liquidated entry within the Protest window so adverse decisions get challenged before the deadline expires.

What can I Protest?
Expandable icon for frequently asked question section

Adverse liquidation decisions, rate advances, denied PSC claims, denied drawback claims, and other CBP determinations affecting duty owed. The Protest mechanism covers the full range of post-liquidation disputes: classification, valuation, country of origin, trade program denials, exclusion decisions. If CBP's call cost you money and the entry has liquidated, a Protest is how you challenge it.

How is a Protest different from a Post-Summary Correction?
Expandable icon for frequently asked question section

Timing and posture. PSCs are filed before liquidation, within 314 days of entry, to correct your own errors proactively. Protests are filed after liquidation, within 180 days, to challenge a CBP decision.  PSCs are corrections; Protests are disputes. Caspian files both, and Trade Audit determines which path applies to which entry based on its status.

Do I need a customs attorney to file a Protest?
Expandable icon for frequently asked question section

You don't need an attorney to file a Protest, but you do need someone who knows how to build the legal argument, cite the relevant rulings, and prepare the documentation CBP requires. Caspian has licensed customs brokers in-house who handle the filing. Protests requiring deeper legal escalation, such as to the Court of International Trade, are outside the platform's scope and would route to outside counsel.

What does it cost to file a Protest with Caspian?
Expandable icon for frequently asked question section

Protest filing starts at 2% of claim size, with a $100K annual cap, and $300 per protest after the cap is reached. Pricing is proportional to claim size, and large-scale protests are negotiated directly. Full pricing is on the platform pricing page.

What happens if CBP denies my Protest?
Expandable icon for frequently asked question section

A denied Protest can be appealed administratively or escalated to the Court of International Trade, which is the federal court with jurisdiction over CBP disputes. Court-level escalation is outside the scope of Caspian's platform and would require outside trade counsel. Most disputes resolve at the Protest stage without needing to go further.

How does Caspian know which entries need a Protest?
Expandable icon for frequently asked question section

Trade Audit identifies them. The platform scans your liquidated entries, flags the ones with adverse CBP decisions still inside the 180-day Protest window, and routes them into the Protest pipeline. Entries that should have been corrected via PSC but weren't, and that have since liquidated, also surface here. The audit determines the path. The platform files the challenge.
