What Is Form 19 Protest and When Do You Need It?

TL;DR – Form 19 protest is the path for IEEPA entries that were liquidated more than 80 days ago and cannot go through CAPE Phase 1. You have 180 days from the liquidation date to file. For February 2025 entries, that deadline is approximately June 2026. After the deadline passes, those duties are not recoverable.
What Is a Form 19 Protest?
A Form 19 protest is the formal mechanism for challenging a CBP decision after an entry has been liquidated. Under 19 U.S.C. § 1514, an importer has 180 days from the date of liquidation to file a protest contesting the duties assessed.
For the IEEPA refund, Form 19 protest serves one specific purpose: recovering duties on entries that were liquidated more than 80 days ago and therefore fall outside CAPE Phase 1 eligibility. CAPE handles the recent entries; Form 19 handles the older ones.
PSC vs Protest for IEEPA Refunds
These two get conflated. They are different mechanisms with different outcomes.
PSC for an IEEPA refund: rejected. Post Summary Corrections filed specifically to recover IEEPA duties are not accepted. Once CAPE accepts an entry, all PSCs on that entry are blocked until liquidation under Error Code 864 (CSMS #68397097). The block is entry-wide, not just IEEPA lines. CBP confirmed this directly to NCBFAA: PSCs must be used to correct entry data before CAPE Declaration, never to initiate the refund.
Protest for an IEEPA refund: still accepted. Holland & Knight's April 22, 2026 guidance confirms that protests filed solely for IEEPA duties may be withdrawn within 80 days of liquidation and the entry refiled via CAPE. For entries past the 80-day window, the protest preserves §1514 rights through the 180-day cliff while Phase 2 develops.
Practical sequence. If an entry was already protested before CAPE Phase 1 launched: check the liquidation date. Within 80 days, withdraw the protest and file CAPE. Past 80 days, keep the protest open as your placeholder for Phase 2 or further proceedings. Withdrawing a protest on a liquidated entry outside the CAPE window leaves you with no remaining administrative path.
CAPE Phase 1 vs Form 19 – Which Do You Need?
The right path depends entirely on your entry's liquidation status and timing:
| Liquidation Status | Time Since Liquidation | Correct Path |
|---|---|---|
| Unliquidated | N/A | CAPE Phase 1 |
| Liquidated | ≤80 days ago | CAPE Phase 1 |
| Liquidated | 81–180 days ago | Form 19 protest |
| Liquidated | >180 days ago | No path available |
| Suspended or Extended | N/A | CAPE Phase 1 |
If you're unsure where your entries fall, check the Liquidation Status and Liquidation Date fields in your ES-003 report. See How to Pull the ES-003 Report for instructions on adding those fields.
Form 19 Deadlines for IEEPA Entries
The 180-day protest window starts on the liquidation date – not the entry date. A standard formal entry liquidates approximately 1 year after the entry date under 19 U.S.C. § 1504, which means:
| Entry Period | Approx. Liquidation | Protest Deadline | Urgency |
|---|---|---|---|
| February 2025 | ~December 2025 | ~June 2026 | ⚠️ File now |
| March 2025 | ~January 2026 | ~July 2026 | ⚠️ Urgent |
| April 2025 | ~February 2026 | ~August 2026 | Approaching |
| May 2025 | ~March 2026 | ~September 2026 | Upcoming |
| June 2025 | ~April 2026 | ~October 2026 | Later |
These are approximations based on the standard liquidation cycle. Your actual liquidation date will vary. Use the Liquidation Date in your ES-003 to calculate your exact 180-day window.
The June 2026 deadline is the most urgent. If you have February 2025 entries that liquidated in late 2025 and fall outside the 80-day CAPE window, you have until approximately June 2026 to file a Form 19 protest. This is a hard statutory deadline.
How to File a Form 19 Protest
Protests are filed through ACE Portal using the Protest module. You'll need an active ACE importer account – see the ACE Portal Setup Guide if you don't have one.
What to include in your protest:
Entry number – the CBP entry number for each entry you're protesting. You can file one protest covering multiple entries.
Basis of protest – cite the court ruling that found IEEPA tariffs unlawful and CBP's CAPE program as the basis for reliquidation and refund. Reference the relevant IEEPA HTS codes (9903.01.xx or 9903.02.xx) on your entries.
Duty amount – the IEEPA duty amount paid on each entry, drawn from your ES-003 report.
Many importers use a customs broker to prepare and file Form 19 protests, particularly for entries with complex multi-code situations. If you have a large number of entries approaching the June 2026 deadline, start the process now – brokers are seeing high volume.
Frequently Asked Questions
Can I file both CAPE and Form 19 for the same entry? No. If an entry is eligible for CAPE Phase 1 (unliquidated or liquidated within 80 days), use CAPE – it's the faster and more direct path. Form 19 is for entries outside the CAPE window. Filing a protest for an entry already in a CAPE Declaration creates a conflict; use one path per entry.
What happens after I file Form 19? CBP reviews the protest and, if approved, reliquidates the entry and issues a refund. The timeline for protest review is not published – it depends on CBP workload. Filing before the deadline is what matters; approval timing is outside your control. Unlike CAPE, there's no published 45-day or 60–90 day timeline for protests.
Do I need a lawyer to file Form 19? No. Many importers file Form 19 protests themselves through ACE Portal or with the help of a licensed customs broker. You do not need a lawyer. A customs broker is sufficient for straightforward IEEPA protest filings.
What if CBP announces Phase 2 before my protest deadline? If CBP announces a Phase 2 that covers your entries before your protest deadline, you may be able to use Phase 2 instead. As of May 2026, CBP has not announced a Phase 2 launch date and has explicitly declined to provide details. Industry expectation is Q3-Q4 2026, but that is not a CBP commitment. Don't wait for Phase 2 if your protest deadline is approaching – file the protest to preserve your rights, and if Phase 2 emerges, you can evaluate it then.
Will CBP Actually Pay If I File Form 19?
The honest answer: the legal sources conflict on this point. Here is what each one says.
The favorable read. In AGS Company Automotive Solutions v. United States (Slip Op. 25-154, U.S. Court of International Trade, December 15, 2025), the U.S. government stated on the record that it "will not object to the court ordering reliquidation of plaintiffs' entries subject to the challenged IEEPA duties if such duties are found to be unlawful." Holland & Knight's April 22, 2026 guidance treats this, combined with the SCOTUS ruling and CAPE rollout, as sufficient basis for protests to recover IEEPA duties.
The cautious read. Troutman Pepper's December 19, 2025 analysis of the same AGS decision is more guarded. The ruling is narrow to CIT plaintiffs. Per Troutman: "Importers who have not filed suit cannot rely on this decision as assurance that liquidation will be 'fixed' later through systemic administrative action." And: refunds "may not be recoverable solely through filing administrative protests under 19 U.S.C. § 1514(a)." Under this reading, only CIT litigation under 28 U.S.C. § 1581(i) is fully reliable for non-plaintiff importers.
Why the conflict. Troutman was written in December 2025, before SCOTUS struck down IEEPA tariffs (Feb 20, 2026) and before CBP launched CAPE (Apr 20, 2026). Holland & Knight wrote after both. The administrative landscape changed materially in between. Holland & Knight is more recent. Troutman's underlying legal point — that AGS itself is narrow to plaintiffs — is not invalidated by later events.
Practical move. For entries past the 80-day CAPE window but inside the 180-day protest cliff, filing a timely protest is the cheap option that preserves all paths. It costs little, can be withdrawn if Phase 2 covers the entry later, and keeps §1514 rights alive while the legal question resolves. The expensive alternative — a CIT action under § 1581(i) — is the only fully guaranteed path for non-plaintiffs under Troutman's reading, with a two-year statute of limitations from liquidation. Most importers will file the protest first and escalate to CIT only if a significant refund hangs on it.
The one move with no defensible upside: missing the 180-day deadline entirely. That closes the cheapest path and leaves only the expensive one.
