The Complete CBP Form 19 Protest Guide
The CBP Form 19 protest is the first formal mechanism for challenging CBP duty determinations and recovering overpaid IEEPA tariffs. The 180-day deadline from entry liquidation is absolute — missing it eliminates CBP protest as a recovery option.
- 180-day deadline is HARD — no extensions without extraordinary circumstances
- Form 19 processing typically takes 3–6 months for a CBP decision
- Protest must be “distinct and specific” — requires a detailed written memo with supporting evidence
- Successful protests can recover principal duties + interest at the Treasury rate
- Multi-entry protests allowed when same party, same merchandise category, and common issues
⚠ The 180-Day Deadline: Non-Negotiable
For entries made on or after December 18, 2004, protests must be filed within 180 days after the date of notice of liquidation (19 CFR § 174.12(e)). The liquidation notice date is posted electronically on CBP.gov — that posting date is the legal evidence of liquidation (19 CFR § 159.9).
Current deadline window: IEEPA entries that liquidated in late 2025 have protest deadlines closing through mid-2026. Entries that liquidated in September 2025 could have deadlines expiring as soon as late March 2026. Check your liquidation dates immediately.
If you miss this window, CBP protest is permanently closed for that entry. You may still have options through the Tucker Act (6-year statute of limitations), but the CBP administrative path is gone.
What Is a CBP Form 19 Protest?
A CBP protest is the formal administrative mechanism for challenging decisions by U.S. Customs and Border Protection. Under 19 U.S.C. § 1514, protestable decisions include the classification and rate of duties, all charges or exactions within CBP’s jurisdiction (including interest), and the liquidation or reliquidation of an entry.
For IEEPA tariff recovery, the protest challenges the tariff as an unlawful charge or exaction — duties assessed under an authority (IEEPA) that the Supreme Court has ruled does not authorize tariffs. The legal basis is straightforward: Learning Resources, Inc. v. Trump invalidated the IEEPA tariff authority, and duties collected under that authority are recoverable.
Legal authority: 19 U.S.C. § 1514 (decisions subject to protest); 19 CFR Part 174 (protest procedures); 19 CFR § 174.11 (matters subject to protest). Full statutory text at govregs.com.
Step-by-Step: How to File Your Protest
Build Your Entry Universe
Assemble a complete list of all entries where IEEPA tariff lines were assessed, from April 2025 through February 20, 2026. For each entry, capture:
- Entry number, port code, entry date, and importer of record number
- HTS classification(s) and the tariff line(s) assessed (look for Chapter 99 IEEPA lines)
- Amount of duties/tariffs paid and the payment date/method
- Broker and filer information (ABI/ACE reference numbers)
- Supporting evidence tying the assessed tariff to the IEEPA program (rate line, program indicator)
Tip: Use the ACE Portal Guide for step-by-step instructions on pulling this data.
Determine Liquidation Status
For each entry, identify whether it is unliquidated/suspended or liquidated. The liquidation date is the primary trigger for the protest deadline.
Liquidation is CBP’s final computation of duties for an entry (19 CFR § 159.1). The notice of liquidation is posted on CBP.gov, and that posting date is the legal evidence of liquidation (19 CFR § 159.9).
For unliquidated entries: Following the March 4, 2026 Eaton order, CBP is directed to liquidate without IEEPA duties. Monitor and verify.
For liquidated entries: Calculate your 180-day deadline from the liquidation notice date. Prioritize entries closest to expiration.
Prepare the Protest Package
Your protest filing consists of two components: the CBP Form 19 itself and the protest memo (legal justification attachment).
CBP Form 19 — Required Fields
Form 19 must be filed in quadruplicate unless submitted electronically through ACE. Required contents under 19 CFR § 174.13:
- Protestant identity: Name, address, and importer number of the importer of record (or consignee). If represented by agent/attorney, include their information.
- Entry information: Entry number(s) and date(s) of entry.
- Liquidation date: The date of liquidation for each entry (or the date of the decision being protested).
- Merchandise description: Specific description of the merchandise affected.
- Objection: The nature of and justification for the objection, set forth distinctly and specifically with respect to each category, payment, claim, decision, or refusal.
- Drawback declaration: Whether the entry is or could be subject to drawback.
Write the Protest Memo
The protest memo is the heart of your case. It is the legal justification attachment that transforms Form 19 from a cover sheet into an argument. Structure it as follows:
Section A: Statement of Facts
Identify the importer, the entries at issue, the IEEPA tariff lines assessed, the amounts paid, and the liquidation dates. Attach the entry schedule showing all affected entries.
Section B: Legal Argument
State that the duties were assessed under IEEPA executive orders that the Supreme Court invalidated in Learning Resources, Inc. v. Trump. Cite the decision. Argue that the assessed duties constitute unlawful charges or exactions under 19 U.S.C. § 1514(a)(3) because they were collected under an authority that does not authorize tariffs.
Reference the March 4, 2026 CIT order in Atmus Filtration, Inc. v. United States confirming that all importers are entitled to the benefit of the ruling.
Section C: Prayer for Relief
Request reliquidation of the identified entries without IEEPA duties, refund of excess deposits, and interest under 19 U.S.C. § 1505(c) from the date of deposit to the date of reliquidation.
File the Protest
File with CBP either at the port of entry or electronically through ACE (19 CFR § 174.12(d)). The protest is deemed filed on the date it is received by CBP.
Multi-entry protests: A single protest may cover multiple entries if all entries involve the same protesting party, the same category of merchandise, and a common decision or issue (19 CFR § 174.13(b)). This is the recommended approach for IEEPA protests — it reduces administrative burden significantly.
Refund mailing instructions: You may append a statement directing refunds “in care of” a named agent. This supersedes any existing Form 4811 designation (19 CFR § 174.13(c)).
Fifth copy for proof of receipt: If you present a fifth copy, CBP will date-stamp it and return it to you as proof of filing (19 CFR § 174.12(g)).
After Filing: What Happens Next
Once filed, CBP reviews the protest. The typical process:
- Days 1–5: CBP acknowledges receipt and assigns a protest number.
- Days 6–30: CBP may request additional information (optional).
- Days 31–60: Your response period if CBP requests information.
- Days 61–180 (typical): CBP review and decision — either approval (reliquidation + refund) or denial.
If CBP allows the protest: CBP reliquidates the entries and issues refunds of excess deposits plus interest under 19 U.S.C. § 1505(b)-(c). Refunds must be paid within 30 days of reliquidation (19 CFR § 24.36(a)(2)).
If CBP denies the protest: You have 180 days from the denial to file suit in the U.S. Court of International Trade under 28 U.S.C. § 1581(a). See the CIT Litigation Roadmap.
Timeline: Filing to Decision
Amending Your Protest
A protest may be amended at any time before the 180-day filing period expires (19 CFR § 174.14). Amendments can add claims, entries, or grounds. If you discover additional IEEPA entries after filing, amend promptly rather than filing a new protest.
Amendments must be filed in quadruplicate on Form 19 (or equivalent) labeled “Amendment to Protest” and must reference the original protest number and date.
Common Pitfalls to Avoid
❌ Pitfalls That Forfeit Refund Rights
- Missing the 180-day window. Count from the liquidation notice posting date on CBP.gov. Calendar it for every entry.
- Filing an inadequate protest. Objections must be “distinct and specific” — a protest that simply cites the Learning Resources decision and requests money back is insufficient. Include entry numbers, liquidation dates, amounts, and a legal basis.
- Assuming refunds are automatic. The Supreme Court ruling establishes the legal predicate, but recovery requires procedural action. CBP will not proactively refund without a protest or court order.
- Incomplete entry universe. Multi-port importers often miss entries. Run a comprehensive ACE report across all ports and date ranges.
- Not preserving payment records. ACE entry summaries, broker billing statements, and ACH confirmations are essential evidence. Preserve them now.
- Waiting on CBP indefinitely. If CBP is slow to act on your protest, evaluate CIT litigation in parallel to preserve your rights.
Cost and Fee Estimates
| Service | Fee Structure | Notes |
|---|---|---|
| CBP Protest Filing | Flat fee based on volume of claims | Includes entry audit, protest preparation, Form 19 filing, and protest memo |

CBP Protest vs. Other Recovery Options
| Scenario | Best Path | Why |
|---|---|---|
| Entries liquidated, 180-day window open | CBP Protest (Form 19) | Fastest, lowest cost, first step for most importers |
| CBP denies the protest | CIT Litigation | 180 days from denial to file. Judge Eaton handling all IEEPA cases. |
| 180-day protest window already closed | Tucker Act (Court of Federal Claims) | 6-year statute of limitations. Safety net for early IEEPA entries. |
| Entries unliquidated | Monitor + verify | Eaton order directs CBP to liquidate without IEEPA duties. Verify in ACE. |
| Substantial exposure ($500K+) | Protest + CIT in parallel | File protest administratively while preparing CIT complaint for faster resolution. |
Frequently Asked Questions
Do I need a lawyer to file Form 19?
Not legally required. An importer of record, consignee, or authorized agent can file (19 CFR § 174.12(a)). However, the protest memo — the legal justification — benefits significantly from legal expertise. A poorly drafted protest can be denied on procedural grounds even when the substantive claim is strong.
Can I file the protest myself?
Yes. You or your customs broker can file. The Form 19 itself is straightforward. The challenge is drafting a protest memo that is “distinct and specific” enough to satisfy CBP and, if necessary, survive CIT review.
What if CBP requests additional information?
Respond promptly and completely. CBP may request clarification on entry data, legal arguments, or supporting documentation. Delayed or incomplete responses can slow the process and, in some cases, result in denial.
What if I miss the 180-day deadline?
CBP protest is permanently closed for that entry. However, the Tucker Act provides an alternative through the Court of Federal Claims with a six-year statute of limitations. See our Tucker Act guide.
Can I appeal a CBP denial?
There is no administrative appeal of a protest denial within CBP. The remedy is to file suit in the U.S. Court of International Trade within 180 days of the denial under 28 U.S.C. § 1581(a). See the CIT Litigation Roadmap.
Can I consolidate entries from multiple ports?
Yes. A single protest may cover multiple entries from different ports if all involve the same protesting party, the same category of merchandise, and a common decision (19 CFR § 174.13(b)). File with CBP at any port or electronically.
How is interest calculated on refunds?
Under 19 U.S.C. § 1505(c), interest accrues at a rate determined by the Secretary of the Treasury from the date duties were deposited to the date of liquidation or reliquidation. The specific rate is published periodically by Treasury.
