How to File a CBP Protest for IEEPA Tariff Refunds

Understanding 19 USC 1514: Your Protest Rights

Section 1514 of Title 19 gives importers the right to protest CBP decisions within 180 days of liquidation. This includes challenging the assessment of duties, classification decisions, and valuation determinations.

For IEEPA tariff refunds, you're protesting:

• • The assessment of IEEPA-based additional duties
• • CBP's legal authority to collect those duties
• • The constitutional validity of the underlying tariff authority

What Can Be Protested

Step 1: Gather Required Information

Before filing any protest, you need complete information about the entries you're protesting. Here's your checklist:

Essential Entry Information

• • Entry number: 11-digit CBP entry number
• • Entry date: Date goods were entered for consumption
• • Liquidation date: Date CBP finalized the duty assessment
• • Port of entry: Where goods were imported
• • Filer code: Your importer ID in CBP systems
• • HTS classification: 10-digit Harmonized Tariff Schedule code
• • Declared value: Entered value of the merchandise
• • IEEPA duty paid: Amount of additional duties assessed

Supporting Documentation

• • CF 7501 (Entry Summary): Shows duties assessed and paid
• • Commercial invoice: Supports value and country of origin
• • Bill of lading or airway bill: Proves shipment details
• • Certificate of origin: Documents country of manufacture
• • Payment records: Proof of duty payment

Step 2: Prepare Your Protest Document

A CBP protest is a formal legal document. Here's the structure and content you need:

Required Protest Elements

Legal Arguments for IEEPA Protests

1. Constitutional Challenge:

"The assessment of additional duties under IEEPA Proclamation [Number] violates Article I, Section 8 of the U.S. Constitution, which grants Congress exclusive authority to impose duties. The Supreme Court's decision in Learning Resources Inc. v. Trump (2026) held that IEEPA does not grant the President authority to impose tariffs."

2. Statutory Authority Challenge:

"CBP lacked legal authority to assess and collect the additional duties imposed under IEEPA. The International Emergency Economic Powers Act does not extend to customs duties, as definitively determined by the Supreme Court."

3. Request for Relief:

"Protestant requests immediate refund of all IEEPA-based additional duties, plus accrued interest from the date of payment, and correction of the customs record to reflect the proper duty assessment."

Step 3: File the Protest

Where to File

File your protest with the CBP Port Director where the original entry was made. Do not file at a different port or with CBP headquarters.

Filing Methods

• • Electronic filing (recommended): Through ACE Portal protest module
• • Mail: Certified mail with return receipt requested
• • Hand delivery: In-person filing at port office
• • Email: Some ports accept PDF protests via email (verify first)

Required Forms

• • CBP Form 19: Customs duty payment (if additional payment required)
• • Power of Attorney (CBP Form 5291): If filing through customs broker
• • Protest letter: Your legal arguments and supporting documentation

Step 4: Pay Any Additional Duties (If Required)

In some cases, CBP may require payment of additional duties to perfect your protest. This typically happens when:

• • The protest challenges classification and a higher duty rate applies
• • There's a valuation dispute requiring additional payment
• • CBP claims additional duties are owed beyond IEEPA tariffs

For IEEPA-only protests: No additional payment should be required since you're challenging the legal authority to collect, not the amount assessed.

Common Mistakes That Kill Protests

Deadline Errors

• • Filing 181 days after liquidation: Even one day late = protest dismissed
• • Using entry date instead of liquidation date: Wrong deadline calculation
• • Assuming unliquidated entries don't need protests: Still file to preserve rights

Documentation Errors

• • Wrong entry numbers: Protesting entries that weren't subject to IEEPA
• • Incomplete identification: Missing liquidation dates or entry details
• • No supporting evidence: Failing to attach entry summaries or payment proof

Legal Argument Errors

• • Mixing IEEPA with other tariffs: Protesting Section 232 duties as IEEPA
• • Vague constitutional arguments: Not citing specific Supreme Court precedent
• • Unclear relief requests: Not specifying refund amount or interest

When to Hire a Customs Broker

DIY-Friendly Situations

• • Simple IEEPA-only protests: Clear-cut constitutional challenge
• • Small dollar amounts: Under $100K total exposure
• • Good documentation: You have all entry records and payment proof
• • Recent liquidations: Plenty of time before 180-day deadline

When Professional Help Is Worth It

• • Large dollar exposure: $500K+ in potential refunds
• • Complex entry patterns: Multiple classification or valuation issues
• • Missing documentation: Incomplete records or payment disputes
• • Approaching deadlines: Less than 30 days to file
• • Corporate compliance: Need audit trail and professional representation

Typical Costs

• • Simple protest preparation: $2,500-$5,000
• • Complex multi-entry protests: $10,000-$25,000
• • Ongoing representation: $500-$1,000/hour for appeals

What Happens After You File

CBP Review Timeline

• • Acknowledgment: CBP confirms receipt within 5-10 business days
• • Initial review: CBP determines if protest is complete and timely
• • Substantive review: CBP analyzes legal arguments and documentation
• • Decision: Grant, denial, or request for additional information

Expected Outcomes for IEEPA Protests

Given the Supreme Court's clear ruling, well-prepared IEEPA protests should be granted. However, expect:

• • Automatic grants: For protests citing Learning Resources precedent
• • Batch processing: CBP will likely handle similar protests together
• • Refund delays: Grant doesn't mean immediate payment
• • Interest calculations: CBP must determine proper interest amounts

If Your Protest Is Denied

In the unlikely event CBP denies a post-SCOTUS IEEPA protest, you have options:

Administrative Appeals

• • File further review request with CBP within 180 days
• • Escalate to CBP headquarters for policy guidance
• • Request expedited review based on Supreme Court precedent

Judicial Review

• • File 1581(a) action in Court of International Trade
• • Challenge CBP's denial as contrary to Supreme Court precedent
• • Seek injunctive relief and immediate refund
