CBP Form 19 Protest Guide

Preserve Administrative Refund Rights

For liquidated IEEPA entries, the protest window may control the next step.

CBP Form 19 is the traditional administrative protest mechanism for challenging certain CBP decisions after liquidation. For IEEPA tariff refunds, the key questions are whether the entry has liquidated, whether liquidation is final, whether the protest period remains open, and whether the protest file contains enough documentation to preserve recovery.

Court Status — April 7, 2026

Judge Eaton’s order strengthens refund rights, but protest posture still matters.

In Euro-Notions Florida, Inc. v. United States, Judge Eaton confirmed that all importers of record whose entries were subject to IEEPA duties are entitled to the benefit of the Supreme Court’s Learning Resources decision. The order directs CBP to liquidate or reliquidate entries without regard to IEEPA duties, including liquidated entries, but suspends immediate compliance.

Practical result: companies should still identify liquidated entries, confirm whether protest rights remain open, and preserve administrative claims where the protest path is available.

When Form 19 Matters

Use the protest path when liquidation has occurred and administrative rights remain open.

A CBP protest is not the starting point for every refund claim. It is most important where an entry has liquidated and the importer must preserve administrative rights before the protest period expires. The analysis begins with the entry record, not with the form.

Entry identified

The affected entry number, importer of record, broker, HTS line, and IEEPA duty amount are known.

Liquidation confirmed

The official liquidation date and status have been verified through ACE, CBP posting, or broker records.

Deadline open

The protest period remains open or must be urgently reviewed before administrative rights are lost.

Documentation ready

The importer can support the protest with payment proof, line-item detail, and legal/procedural grounds.

The protest clock can be unforgiving.

For liquidated entries, the protest deadline is often the most immediate risk. Do not assume that a favorable court order automatically protects every entry without confirming liquidation status, finality, and available administrative remedies.

Sort affected entries by liquidation date and review the oldest open deadlines first.

Protest Process

Build the protest file before filing the protest.

1

Identify entries

Build the entry universe and isolate entries that include IEEPA tariff lines and duty deposits.

2

Confirm liquidation

Verify liquidation status and liquidation date for each entry before choosing the protest pathway.

3

Prepare Form 19

Identify the protested decision, requested relief, legal basis, entries, duty amounts, and supporting documents.

4

Track decision

Monitor CBP action, refund processing, denial, accelerated disposition, and potential CIT deadlines.

Form 19 Preparation

Information the protest file should contain.

The strongest protest file connects the form to the entry record. Each protested entry should be traceable to the IEEPA duty line, the amount paid, the liquidation date, and the requested refund.

Protest Item What to Include Why It Matters
Importer of record Legal name, importer number, address, and authorized filer information. Identifies the party tied to the customs record and refund channel.
Entry numbers Each entry covered by the protest, with entry date and port. Allows CBP to match the protest to the correct transactions.
Liquidation date Official liquidation date for each entry. Determines whether the protest is timely.
Protested decision Assessment or liquidation of IEEPA duties, with reference to the affected duty lines. Defines what CBP action the importer is challenging.
Requested relief Reliquidation or refund without regard to IEEPA duties, plus lawful interest where available. States what the importer wants CBP to do.
Legal basis Supreme Court and CIT refund rulings, plus entry-specific facts. Connects the legal ruling to the importer’s entries.
Duty calculation IEEPA duty paid by entry and line item. Supports refund amount and later verification.
Attachments Entry summaries, ACE records, broker statements, payment proof, liquidation notices, and calculation schedule. Creates an audit-ready administrative record.

Broker and Counsel Roles

Use the broker for data and filing mechanics. Use counsel for legal strategy.

Customs brokers are essential for ACE data, entry exports, liquidation status, and electronic filing mechanics. But legal arguments, protest strategy, CIT litigation review, assignment questions, and court deadlines require specialized legal analysis.

Broker role

  • Pull ACE reports.
  • Identify affected entries and duty lines.
  • Confirm liquidation status.
  • Support electronic filing.
  • Track CBP status updates.

Counsel / specialized review role

  • Draft legal protest grounds.
  • Evaluate timeliness and jurisdiction.
  • Prepare CIT strategy after denial.
  • Review claim ownership and assignment issues.
  • Protect court deadlines.
After Filing

Track the protest until refund, denial, or court review.

Acceptance and control number

Confirm CBP accepted the protest and record the protest number, filing date, and covered entries.

Supplementation

Provide additional documents if CBP requests proof of payment, entry detail, or calculations.

Refund verification

If allowed, track refund principal, interest, payee, and accounting treatment.

Denial and CIT review

If denied, evaluate timing and strategy for Court of International Trade review.

Common protest mistakes to avoid.

Filing without a complete entry universe

A protest that omits entries may leave money unrecovered or force later scrambling. Start with a complete ACE and broker data pull.

Assuming one deadline applies to all entries

Different entries may have different liquidation dates. Deadline review should be entry-by-entry.

Mixing IEEPA with other tariff programs

Section 232, Section 301, and IEEPA may all use Chapter 99 lines. Keep recoverable IEEPA duties separate.

Ignoring tax and pass-through issues

Refund proceeds may raise customer, exporter, affiliate, accounting, and tax questions.

Common Questions

Frequently asked protest questions.

Do all IEEPA refund claims require a CBP protest?

No. Unliquidated entries, entries subject to court-directed processing, or entries in other procedural postures may require a different pathway. The protest path is most important where liquidation has occurred and the protest period remains open.

Can one protest cover multiple entries?

In many situations related entries can be grouped, but the protest must still identify the affected entries, deadlines, duty amounts, and requested relief clearly enough for CBP review.

Can the broker file the protest?

A broker may be able to file as an authorized agent, but legal strategy, drafting, and preservation of later court rights should be reviewed carefully.

What if CBP denies the protest?

A denied protest may trigger the need to evaluate Court of International Trade review. Track denial dates immediately and coordinate with trade counsel.

Should tax and accounting teams be involved before filing?

Yes. Refund principal, interest, customer credits, prior deductions, COGS, and inventory treatment should be tracked before the refund arrives.
