CBP Form 19 is the instrument the United States government provides for an importer to say “I disagree with this decision and I would like my money back.” It is old, it is short, and it is more powerful than most importers realise. For the current wave of IEEPA tariff refunds, it is the primary legal channel through which the protest right recognised in 19 U.S.C. § 1514 is exercised.
This post is a conceptual guide, not a walkthrough. We will explain what Form 19 is, what it does, the categories of decisions it can challenge, and the practical constraints that trip importers up. We will not provide a step-by-step how-to, for reasons we are transparent about at the end.
What Form 19 is
Form 19 is a three-page PDF maintained by Customs and Border Protection under OMB Control Number 1601-0017. It is the document that operationalises the right to protest a CBP decision. That right is statutory — Congress wrote it into 19 U.S.C. § 1514 — and the mechanics of filing are set out in regulation at 19 C.F.R. Part 174.
The form has six sections. They ask for identifying information about the importer, the entry being protested, the nature of the objection, and the relief being requested. The most consequential field is the one asking for the legal and factual basis for the protest — the place where the importer explains why CBP’s decision was wrong.
Form 19 is not branded. It is a plain government form. Anything marketed as a “Tariff Spot protest form” or a proprietary refund document is either Form 19 with a sticker on it or something that is not legally a protest. The distinction matters: only a properly completed Form 19 (or an equivalent electronic submission through ACE) satisfies the regulation.
What Form 19 can protest
The statute lists the decisions an importer can contest via Form 19. They are broader than most people assume:
- The classification of merchandise and the resulting duty rate
- The appraised value of the goods
- The exclusion of merchandise from entry (i.e., CBP refuses to let the goods in)
- The liquidation or reliquidation of an entry
- Drawback claims (refunds on exported goods)
- Demands for redelivery of goods already released
- Country-of-origin marking determinations
- Charges and exactions — Merchandise Processing Fee, Harbor Maintenance Fee, and similar line items
For the current IEEPA refund wave, the relevant category is liquidation: the importer is arguing that CBP liquidated the entry at a duty rate that included tariffs the Supreme Court has since ruled unlawful, and that the correct liquidation should have excluded those tariffs.
Who can file a protest
The regulation at 19 C.F.R. § 174.12 recognises several categories of filer:
- The importer of record — the entity whose name and IRS/EIN appear on the entry summary. In the vast majority of cases, this is who files.
- The consignee, where different from the importer of record
- A surety that issued the customs bond on the entry
- An authorised agent acting on behalf of one of the above
Importers have the legal right to file their own protests. You do not need a customs broker, and you do not need a trade attorney. There is no rule that says otherwise. The reason most importers historically used a broker is that the broker already held the entry data and knew the procedure — not because the procedure was reserved for licensed professionals.
One important nuance: under 19 U.S.C. § 1641, the act of filing a protest “on behalf of” an importer in a capacity that constitutes customs business is reserved for licensed customs brokers. This is why Tariff Spot does not file protests for customers. We prepare the document; the importer remains the filer of record and signs the form in their own name.
When Form 19 has to be filed
The deadline is 180 days from the date of liquidation, set by 19 U.S.C. § 1514(c)(3). The deadline is jurisdictional, which in practice means CBP treats a late protest as a filing it has no authority to consider — not as a filing it chooses to reject. There is no discretion, no hardship waiver, and no extension. If the 180th day falls on a weekend or federal holiday, the deadline rolls to the next business day; that is the only forgiveness the regulation provides.
The liquidation date is not the entry date, not the date the goods arrived, and not the date CBP sent the importer anything. It is a specific event in the entry lifecycle, and it is published. Most entries liquidate somewhere between ten months and a year after the entry date, though the timing varies. Our deadline deep-dive covers the mechanics.
What a valid protest has to contain
The regulation at 19 C.F.R. § 174.13(a) sets out the exhaustive list of required contents. In substance, the importer must provide:
- Their name, address, and importer-of-record number
- The entry number and date
- The date of liquidation
- A description of the goods affected
- A specific statement of the objection and its legal or factual basis
- A reference to any prior related protest that is subject to further review
- A non-collusion certification if a surety is filing
- A declaration about whether the entry is the subject of a drawback claim
That list is worth reading twice because it does not include several things people often assume are required: ACH enrollment, bank account details, a completed refund delivery address, or participation in the ACE portal. The refund delivery block on Form 19 is explicitly optional under 19 C.F.R. § 174.13(c), which uses the words “if desired” and “may.” A protest with those fields left empty is legally valid. The refund delivery mechanics are governed by a separate body of law — we cover that distinction in the ACH enrollment guide.
What a protest is worth, in plain terms
A successful protest produces a reliquidation of the entry. CBP recalculates the duty at the corrected figure, and the difference between what was paid and what should have been paid is refunded to the importer. Statutory interest may also accrue on the refunded amount under 19 U.S.C. § 1505(b).
For IEEPA protests, the recovery equals the full IEEPA-attributable duty on the entry. On a reciprocal-tariff entry with a 10% duty layer, that is 10% of the entered value — often a meaningful number on even one shipment, and a significant one across a year of imports.
Why this post does not include a step-by-step walkthrough
We are being direct about this. Tariff Spot is a commercial service that prepares Form 19 protests at a flat fee and mails them to CBP in the format the regulation requires. A blog post that walks the reader through every field mapping, port routing rule, and attachment norm would be a product manual for a free version of the service we charge for.
Everything in this post is public law. Anyone with enough time, a copy of 19 C.F.R. Part 174, and the patience to work through port-specific administrative quirks can file their own Form 19. The reason most importers pay us to do it is that we have already absorbed the cost of working that out. We have also already absorbed the cost of a mistake — a wrong address, a misrouted envelope, a late postmark — which on a jurisdictional deadline is the difference between a refund and a denied claim.
If you want the short version of the process: tell us your entries, pay the flat fee, sign the generated Form 19. We handle the rest. Start a refund claim.
