CBP Customs Protest: How to Challenge Import Duties and Recover Overpaid Tariffs

A CBP customs protest is a formal administrative challenge you file against a decision by US Customs and Border Protection under 19 U.S.C. § 1514. It's the primary way importers contest classification errors, valuation disputes, incorrect duty rates, or tariff assessments they believe are wrong. You have 180 days from the date of liquidation to file one, and missing that window means losing your right to challenge — permanently.

This matters more right now than at any point in the last decade. On May 7, 2026, the Court of International Trade struck down the 10% Section 122 tariff in Oregon v. Trump and Burlap & Barrel v. Trump, ruling it exceeded the president's authority under Section 122 of the Trade Act of 1974. Five days later, the Federal Circuit issued a temporary stay, keeping the tariff in effect while the appeal proceeds. But the CIT's injunction only covers named plaintiffs. Everyone else who paid Section 122 duties since February 24 needs to take action to preserve their refund rights — and for most importers, that means filing a protest.

What Exactly Is a Customs Protest?

A protest is your formal administrative objection to a CBP decision. It's not a lawsuit — it's a structured process within CBP's own system. Think of it as an appeal before you escalate to court.

Under 19 U.S.C. § 1514, you can protest any of the following CBP decisions:

Classification of merchandise — CBP assigned the wrong HTS code, which changed your duty rate. If you think your product falls under a different HTS heading, the protest is how you challenge that.
Appraised value — CBP valued your goods at a higher amount than you declared, increasing your duty bill.
Rate and amount of duties — the duty rate applied was incorrect, or the math was wrong.
Liquidation or reliquidation — you disagree with how CBP finalized your entry.
Exclusion or denial of entry — your goods were denied entry and you believe that was wrong.
Country of origin determination — CBP determined the origin differently than you declared, which affects whether trade agreement rates or Section 301 tariffs apply.

Here's what's critical: a protest is the only administrative remedy for most duty disputes. If you don't file one within the deadline, you can't take the issue to court later. The Court of International Trade won't hear your case unless you've first exhausted your administrative remedies — and that means filing a protest with CBP.

Why Protests Matter Right Now: The Section 122 Situation

Here's the timeline every importer should know:

February 24, 2026: The administration imposes a 15% tariff on virtually all imports under Section 122 of the Trade Act of 1974, citing balance-of-payments concerns. This was the broadest tariff action under Section 122 in modern history.

May 7, 2026: The CIT rules 2-1 that these tariffs exceed the president's authority. The court found that the US trade deficit doesn't constitute a "fundamental international payments problem" as required by the statute. But the court's injunction is limited — it only covers the three named plaintiffs (Burlap & Barrel, Basic Fun, and the State of Washington). For a detailed analysis of the ruling and what it means for the tariff's July 24 expiration, see our Section 122 guide.

May 12, 2026: The Federal Circuit issues a temporary stay, freezing the CIT's order while the government appeals. Section 122 duties continue to be collected on all covered imports.

What this means for you: If you've paid Section 122 duties on any imports since February 24, CBP is still collecting them. The tariff was found unlawful by one court, but the stay means it's still enforced. If the ruling is ultimately upheld — and the legal consensus leans that direction — importers who filed protests will be positioned for refunds. Those who didn't will likely have no claim.

Should You File a Protest on Section 122 Entries?

This is where it gets complicated. There's genuine uncertainty about whether CBP will accept Section 122 protests. Some trade attorneys argue CBP was acting in a "ministerial capacity" (just collecting what the executive ordered), which would make it a non-protestable decision. Others argue that any duty assessment is protestable under § 1514.

My recommendation: file the protest anyway. Here's why:

If CBP accepts it, you've preserved your rights.
If CBP denies it on jurisdictional grounds, you've at least demonstrated you took action within the deadline — which strengthens any subsequent legal argument.
The cost of filing is essentially zero (just time and documentation).
The cost of NOT filing — if it turns out protests were the correct mechanism — is losing your entire refund claim.

The 180-day clock is ticking from the date each entry liquidates. Early February/March entries are approaching their liquidation dates now. Don't wait for legal clarity that may not come until after your deadline passes.

Who Can File a Protest?

Under 19 CFR § 174.12, these parties have standing to file:

Importer of record — the entity listed as importer on the entry summary (CBP Form 7501). This is you in most cases.
Consignee — the party to whom goods are shipped.
Any person paying charges or exacting duties — if you paid the bill, you have standing.
Authorized agent — a licensed customs broker with your power of attorney. Most importers use their broker to file protests. If you don't have a broker, see our customs bond guide for how to get set up.

You do NOT need an attorney to file a protest. Many importers file through their customs broker, which is faster and cheaper than hiring a trade lawyer for a straightforward protest.

Step-by-Step: How to File a CBP Protest Through ACE

All protests must be filed electronically through CBP's ACE (Automated Commercial Environment) system. Paper filing hasn't been accepted since 2024.

Step 1: Confirm Your Entry Has Been Liquidated

A protest can only be filed after CBP liquidates your entry. Liquidation is when CBP finalizes the duty assessment. You can check liquidation status in ACE by reviewing your entry summary. Liquidation typically occurs 314 days after entry, but CBP can liquidate earlier.

For Section 122 entries made in February-March 2026, liquidation will likely begin in late 2026 or early 2027. However, you should monitor your entries — CBP can accelerate liquidation, and missing the 180-day post-liquidation window would be fatal to your claim.

Pre-liquidation protest: You can file a protest before liquidation in certain situations under 19 U.S.C. § 1514(c)(3). This covers cases where a rate advance or reliquidation determination has been made. Given the uncertainty around Section 122, filing a precautionary protest may be advisable — discuss this with your broker.

Step 2: Calculate Your 180-Day Deadline

The clock starts on the date of liquidation, not the date of entry. You have exactly 180 days.

| Entry Date | Estimated Liquidation | Protest Deadline | |---|---|---| | Feb 24, 2026 | ~Jan 4, 2027 | ~Jul 3, 2027 | | Mar 15, 2026 | ~Jan 23, 2027 | ~Jul 22, 2027 | | Apr 1, 2026 | ~Feb 9, 2027 | ~Aug 8, 2027 | | May 1, 2026 | ~Mar 11, 2027 | ~Sep 7, 2027 |

These are estimates. Actual liquidation can vary. Check ACE for your specific entries.

Step 3: Gather Your Documentation

You'll need:

Entry summary (CBP Form 7501) showing the duties paid
Commercial invoice for the import transaction
Evidence supporting your protest — for Section 122 protests, this is the CIT ruling itself, plus any analysis of why the tariff was incorrectly applied
Legal basis — cite 19 U.S.C. § 1514 and the specific grounds (e.g., "rate and amount of duties" for Section 122)

For classification or valuation protests, you'll also need technical documentation proving why your classification is correct or why CBP's valuation was wrong.

Step 4: File in ACE

Log into ACE at ace.cbp.dhs.gov
Navigate to the Protest module
Create a new protest — reference the specific entry number(s) being protested
Select your protest grounds from the statutory categories (classification, valuation, rate, liquidation, etc.)
Upload your supporting documentation
Submit and save your confirmation number

Pro tip: You can protest multiple entries in a single protest filing, as long as they involve the same issue (e.g., all your Section 122 entries). This saves significant time.

Step 5: Wait for CBP Review

CBP has 2 years to act on your protest. In practice, most protests are reviewed within 6-12 months. You'll receive one of three outcomes:

Allowed — CBP agrees with you and refunds the duties
Denied — CBP disagrees. You have 180 days to appeal to the Court of International Trade.
Deemed denied — if CBP doesn't respond within 2 years, the protest is automatically denied. Your 180-day CIT appeal window starts from that date.

Step 6: Request Further Review (Optional)

If you believe your protest raises a novel legal question or involves a significant amount of money, you can request "further review" under 19 CFR § 174.24. This escalates the protest to a higher review level within CBP. It doesn't extend the 180-day filing deadline, but it can result in a more thorough review. For Section 122 protests involving the constitutional question, further review is worth requesting.

Protest vs. CAPE Refund vs. Duty Drawback: Which Path?

Three different programs can get you money back from CBP. They cover different tariff types and have different requirements. Choosing the wrong one wastes time.

| Tariff Type | Recovery Method | Status | Who Files | |---|---|---|---| | IEEPA reciprocal tariffs | CAPE portal | Active — first refunds arriving May 2026 | Any importer who paid IEEPA duties | | Section 122 (15% global) | Protest (19 U.S.C. § 1514) | Post-CIT ruling, Federal Circuit stay pending | Importer of record or agent | | Section 301 (China 25-100%) | Protest (if exclusion available) | Case-by-case | Importer of record | | Section 232 (steel/aluminum/copper 50%) | Protest (limited success) | Rarely successful | Importer of record | | Classification or valuation error | Protest | Always available | Importer of record | | Duty drawback (goods re-exported) | Separate ACE drawback module | Available permanently | Importer, manufacturer, or exporter |

Can you file both a protest AND a CAPE refund? Not on the same entries. CAPE Phase 1 excludes entries with pending drawback claims. But if you have some entries with IEEPA duties (use CAPE) and others with Section 122 duties (file a protest), you can and should pursue both programs for the respective entries.

When to use drawback instead: If you imported goods and later exported them, duty drawback gets you 99% back regardless of whether the tariff was lawful. Drawback doesn't depend on a court ruling. Check our tariff calculation guide to see exactly which duty layers apply to your imports.

Common Reasons Protests Get Denied

I've seen the same mistakes cost importers millions. Avoid these:

1. Missing the 180-Day Deadline

This is the number one reason. The deadline is absolute — no extensions, no exceptions, no "I didn't know." Set calendar reminders for every entry you plan to protest. If you're unsure whether an entry has been liquidated, check ACE weekly.

2. Wrong Legal Basis

Citing "I disagree with the tariff" isn't a legal basis. You need to reference specific statutory provisions and explain why CBP's decision was incorrect under the law. For Section 122 protests, cite the CIT's May 7 ruling and the statutory analysis.

3. Insufficient Documentation

A protest without supporting evidence is just a complaint. Attach your entry summaries, commercial invoices, and any legal analysis. For classification protests, include binding ruling letters, technical specs, or lab reports.

4. Protesting the Wrong Decision

The protest must target a specific CBP action on a specific entry. Blanket protests against "all Section 122 tariffs" won't be processed. Each entry (or group of related entries) needs its own protest referencing specific entry numbers and liquidation dates.

5. Not Following Up

Filing and forgetting is common. Track your protest status in ACE. If CBP requests additional information, respond promptly. If they deny, calendar the 180-day CIT appeal window immediately.

Dollar Amounts: What Could You Recover?

The recovery depends on your import volume and which tariffs were incorrectly assessed. Here are realistic examples:

Small importer — consumer goods from Vietnam:

Annual Section 122 duties paid: $45,000 (on $300,000 imports at 15%)
If Section 122 is ultimately struck down: $45,000 full recovery

Mid-size importer — electronics components from multiple countries:

Annual Section 122 duties: $225,000 (on $1.5M imports)
Classification error on 20% of entries: additional $18,000
Total potential recovery: $243,000

Large manufacturer — steel and industrial inputs:

Section 122 on non-steel imports: $750,000
Section 232 misclassification on 3 entries: $120,000
Total: $870,000

These aren't hypothetical. Section 122 has been collected on virtually every commercial import since February 24. If you import anything, you've paid it. Run the numbers on your HTS codes.

Frequently Asked Questions

How much does it cost to file a protest?

Nothing — there's no filing fee. Your only costs are the time to prepare documentation and, if you use one, your customs broker's fees (typically $200-500 per protest filing). Given the potential recovery amounts, this is negligible.

Do I need a customs attorney?

For straightforward protests (wrong duty rate, classification error), your customs broker can handle it. For complex constitutional questions like the Section 122 issue, consulting a trade attorney is worth the investment — especially if your exposure is above $50,000. Many trade law firms are taking Section 122 cases on contingency.

Can I still file a protest if I didn't participate in the CIT lawsuit?

Yes. The protest process is separate from the litigation. You don't need to be a plaintiff in Oregon v. Trump to file a protest with CBP. The CIT ruling provides the legal basis, but you're pursuing your own administrative remedy.

What if CBP denies my Section 122 protest?

You have 180 days from the denial to appeal to the Court of International Trade. Given the CIT already ruled Section 122 unlawful, a denied protest followed by a CIT appeal has strong prospects — assuming the Federal Circuit doesn't reverse the CIT.

Does filing a protest delay liquidation?

No. Filing a protest doesn't stop or delay the liquidation of your entries. However, an allowed protest results in reliquidation, where CBP recalculates your duties and issues a refund.

Can I protest entries that haven't been liquidated yet?

In limited circumstances, yes. Pre-liquidation protests are available under 19 U.S.C. § 1514(c)(3) for rate advances and certain other decisions. For Section 122, consider filing a precautionary protest if your entries haven't liquidated — discuss timing with your broker.

What's the deadline for Section 122 protest specifically?

180 days from liquidation of each entry. Since Section 122 entries from February-March 2026 likely won't liquidate until late 2026 or early 2027, you have time — but start preparing now. Don't wait until the deadline is imminent.
