The 180-Day Protest Deadline: Entry-by-Entry Countdown for IEEPA Refunds

Here’s something that catches importers off guard: the 180-day protest deadline for IEEPA tariff refunds isn’t a single date. It’s hundreds — sometimes thousands — of individual dates, one for every liquidated entry in your portfolio.

Entry #1 might have liquidated on December 15, 2025. Its protest deadline is June 13, 2026. Entry #2 might have liquidated on January 22, 2026. Its deadline is July 21, 2026. Entry #437 might have liquidated last week. Its deadline is six months from now.

Every entry has its own clock. Every clock is ticking independently. And when a clock runs out, that entry’s right to a straightforward administrative refund dies with it. The only remaining option is CIT litigation — slower, more expensive, and more complex.

This is why the 180-day protest window isn’t just a concept to understand. It’s a countdown to manage, entry by entry, until every affected entry in your portfolio is protected.

Why the Clock Runs Per Entry

Under 19 U.S.C. Section 1514, the right to protest a liquidation decision expires 180 days after the date of liquidation. Not 180 days after the Supreme Court ruling. Not 180 days after the CIT order. Not 180 days after some universal starting date. 180 days after each individual entry’s liquidation date.

CBP liquidates entries on a rolling basis. Your entries from February 2025 liquidated at different times than your entries from June 2025. Each liquidation starts its own 180-day clock. The result is a staggered set of deadlines spread across weeks or months.

For an importer with 500 IEEPA-affected entries, this means 500 individual deadlines. Some may have already passed. Some may be approaching in weeks. Some may be months away. You won’t know unless you check.

The comprehensive guide to the 180-day window covers the legal framework in detail. This article focuses on the practical mechanics of identifying, tracking, and acting on your specific deadlines.

The IEEPA Liquidation Timeline

IEEPA tariffs took effect on February 4, 2025, and were collected until February 24, 2026 — approximately 12.5 months. CBP typically liquidates entries about 314 days (roughly 10.5 months) after the entry date.

Here’s what that timeline looks like mapped against protest deadlines:

The critical window right now: Entries from February through April 2025 likely liquidated in December 2025 through February 2026. Their 180-day protest deadlines fall between June and August 2026. That’s two to four months away.

If you haven’t filed protests on these entries, they’re your highest priority.

How to Find Your Liquidation Dates

You can’t calculate your deadlines without knowing when each entry liquidated. Here’s how to get that information.

Through the ACE Portal

If you have access to CBP’s Automated Commercial Environment (ACE) portal, pull your ES-003 Entry Summary Details report. Filter for entries with HTS codes beginning with 9903.01 and 9903.02 to isolate IEEPA-affected entries. The report includes a liquidation status field and, for liquidated entries, the liquidation date.

Our ACE liquidation status guide walks through the navigation step by step.

Through Your Customs Broker

Your broker has ACE access and can pull this data on your behalf. Request a comprehensive report of all IEEPA-affected entries with the following fields:

• Entry number
• Entry date
• HTS code(s)
• Duty amount (total and IEEPA-specific)
• Liquidation status (unliquidated, liquidated, finally liquidated)
• Liquidation date (for liquidated entries)

A competent broker should deliver this within a few business days. If they’re unfamiliar with the IEEPA recovery process, the partner program provides broker support resources.

Through an Impact Assessment

An Impact Assessment compiles this data comprehensively, maps all deadlines, and recommends recovery paths for each entry. It’s the most efficient option for importers who want the full picture without doing the research themselves.

Calculating Your Deadlines

Once you have your liquidation dates, the math is simple: liquidation date + 180 days = protest deadline.

But here are some nuances to watch for:

Weekend and Holiday Adjustments

If the 180th day falls on a weekend or federal holiday, the deadline extends to the next business day. However, don’t rely on this — file well before the deadline.

Bulk Liquidation Events

CBP sometimes processes liquidations in batches. If you see a cluster of entries all liquidated on the same date, they’ll all share the same protest deadline. This can create a “cliff” where dozens or hundreds of entries reach their deadline simultaneously.

Extension of Liquidation

In some cases, CBP extends the liquidation period beyond the standard 314 days. This can happen for entries under review, audit, or investigation. Extended liquidation means the entry stays unliquidated longer — which is actually good news, because it keeps the PSC path available.

Suspended Liquidation

Some entries may have their liquidation suspended by court order or administrative action. Suspended entries remain unliquidated and don’t start the 180-day clock until suspension is lifted and liquidation occurs.

Priority Triage: Which Entries Need Attention First

If you have a large portfolio, you can’t address everything simultaneously. Here’s how to triage:

Priority 1: Entries with Less Than 60 Days Remaining

These are your emergencies. File protests immediately. Don’t wait for perfect documentation. Don’t wait for your broker to “get around to it.” A filed protest preserves your rights even if you later need to supplement or amend it.

As of April 2026, entries that liquidated in November-December 2025 fall into this category. These are likely entries originally filed in February-March 2025 — the earliest IEEPA entries.

Priority 2: Entries with 60-120 Days Remaining

These are approaching but not yet critical. Schedule protest filings within the next 30 days. Use this time to gather complete documentation and ensure your protest cites the correct legal basis (the Supreme Court ruling in Learning Resources, Inc. v. Trump).

Entries that liquidated in January-February 2026 typically fall here.

Priority 3: Entries with 120-180 Days Remaining

You have time, but don’t get complacent. Set calendar reminders 90 and 60 days before each deadline. Start gathering documentation and coordinating with your broker or attorney.

Priority 4: Unliquidated Entries

These don’t have a protest deadline yet because they haven’t liquidated. But they do need attention — you should be filing PSCs on these entries right now, while the fast-track correction path is still available. Every day you wait is a day closer to liquidation, which would move them to the protest path.

What a Protest Filing Looks Like

A formal protest under 19 U.S.C. Section 1514 is filed through the ACE portal. Here’s what it includes:

Identifying information: The specific entry number(s), importer of record, and port of entry.

Legal basis: Citation to the Supreme Court’s ruling in Learning Resources, Inc. v. Trump, which held that IEEPA tariffs were unconstitutional. Reference to the CIT’s March 4 order directing universal reliquidation.

Relief requested: Reliquidation of the identified entries without IEEPA duty codes (HTS 9903.01 and 9903.02), and refund of all IEEPA tariffs paid plus statutory interest under 19 U.S.C. Section 1505(c).

Supporting documentation: Entry summaries, proof of duty payment, and any other relevant records.

Your customs broker can file this on your behalf. For complex filings or large portfolios, a trade attorney may provide additional value. Our guide to filing CBP protests for IEEPA tariffs covers the process in detail.

What Happens After You File

Once a protest is filed, several things happen:

The entry stays “not final.” This is the most important immediate effect. A protested entry remains within the scope of the CIT’s universal refund order. An unprotested entry that passes the 180-day mark becomes final and falls outside that scope.

CBP begins administrative review. CBP has up to two years to decide on a protest. Given the volume of IEEPA protests, expect processing to take 18-36 months through the CAPE system.

You can request accelerated disposition. Under 19 U.S.C. Section 1515(b), you can ask CBP to expedite the review. If CBP doesn’t respond within 30 days, the protest is deemed denied — which opens the door to CIT litigation if you want to escalate.

You can still pursue immediate capital. Filing a protest doesn’t prevent you from assigning the claim for immediate payment. Many importers file protective protests to preserve their rights while simultaneously exploring claim assignment for some or all of their entries.

What Happens If You Miss the Deadline

Let’s be direct: missing the 180-day protest deadline is costly.

The entry becomes finally liquidated. The duty assessment is considered final and conclusive. No administrative remedy is available.

CIT litigation becomes your only option. You’ll need a trade attorney admitted to the CIT bar to file an action under 28 U.S.C. Section 1581(i). This involves court filing fees, attorney fees, and a timeline of 12-24 months or longer.

The CIT path has its own deadline. The statute of limitations for CIT claims is two years from the date of the contested government action. Miss that, and the entry is gone entirely.

The cost difference is significant. A protest filing costs broker fees — typically a few hundred dollars per entry or a flat fee for bulk filings. CIT litigation can cost thousands per entry in legal fees. For a portfolio of 200 finally liquidated entries, the difference between timely protest filing and CIT litigation could be tens of thousands of dollars in legal costs alone, not counting the longer timeline.

The cost of waiting analysis quantifies these differences for specific portfolio sizes.

The Rolling Deadline Problem

Here’s what makes the 180-day window particularly challenging for large importers: it’s not a single deadline you can circle on a calendar. It’s a continuous stream of deadlines.

Every week, more entries liquidate. Every liquidation starts a new 180-day clock. And every day, some existing clocks run out.

Example: An importer with 800 IEEPA entries filed between February 2025 and January 2026

Assuming roughly even distribution and standard 314-day liquidation timing:

• ~65 entries liquidate each month
• ~15 entries reach their 180-day protest deadline each week
• At any given time, approximately ~390 entries are in the protest window
• New entries enter the window as they liquidate, old entries exit as their 180 days expire

This means protest filing isn’t a one-time event. It’s an ongoing process that needs to run for months. Every month you delay starting, you lose entries permanently.

Building a Deadline Management System

For importers with large portfolios, managing these deadlines requires a systematic approach:

Step 1: Export All Entry Data

Pull your complete ES-003 report from ACE. Include all entries with IEEPA tariff codes.

Step 2: Categorize by Status

Sort entries into three buckets: unliquidated, liquidated within 180 days, and finally liquidated (180 days expired).

Step 3: Calculate All Deadlines

For every liquidated entry, add 180 days to the liquidation date. Sort by deadline date, earliest first.

Step 4: Create a Filing Calendar

Group entries by deadline month. File protests on the earliest-deadline entries first. Set internal deadlines at least 30 days before the statutory deadline to allow for processing time.

Step 5: Monitor for New Liquidations

Check your liquidation statuses at least monthly (weekly is better). When unliquidated entries liquidate, add them to the protest calendar immediately.

Step 6: File PSCs on Remaining Unliquidated Entries

Don’t forget the entries that haven’t liquidated yet. File PSCs now to recover those funds through the fastest path available.

China-Origin Entries: The Highest-Stakes Deadlines

Importers with China-origin goods face the most urgent deadline situation for a simple reason: China IEEPA rates were the highest in the program. At peak, rates reached 145% — meaning an importer of $1 million in goods from China could have paid $1.45 million in IEEPA duties alone.

These are also among the earliest IEEPA entries, since China was the first country targeted under IEEPA authority. February and March 2025 entries from China are the ones most likely to have already liquidated and to have the nearest approaching protest deadlines.

If you concentrated imports from China during the IEEPA period, your portfolio likely has:

• The largest per-entry refund amounts (due to the high duty rates)
• The earliest liquidation dates (due to early entry dates)
• The nearest approaching protest deadlines (180 days from those early liquidations)

The China IEEPA tariff refund guide provides specific rate schedules, deadline analysis, and recovery strategies for China-origin entries.

For these high-value, time-sensitive claims, filing protests is essential — but you should also evaluate whether immediate capital makes sense for some or all of these entries. When you’re talking about refund amounts in the hundreds of thousands or millions, the time value of waiting 18-36 months for CAPE processing becomes very significant.

Protective Protests: File Now, Decide Strategy Later

There’s a common misconception that you should wait until you have a complete recovery strategy before filing protests. That’s backwards. File the protest first, then figure out your strategy.

A protest preserves your rights. It keeps the entry “not final” under the CIT’s order. It costs relatively little to file. And it doesn’t lock you into any particular recovery approach.

Once the protest is filed, you can:

• Wait for CBP to process it through CAPE (18-36 months)
• Request accelerated disposition to force a faster decision
• Assign the protested claim for immediate capital
• Escalate to CIT litigation if CBP denies or ignores the protest

Filing a protest doesn’t commit you to the government path. It simply preserves your option to use it. Not filing a protest eliminates that option permanently once 180 days have passed.

Think of it as insurance. The cost of filing is minimal. The cost of not filing — losing access to the administrative refund process — could be thousands or tens of thousands of dollars per entry in additional legal fees for CIT litigation.

The post-summary correction guide explains how PSC works for entries that haven’t liquidated yet, while protest filing covers those that have.

The Immediate Capital Alternative

If managing hundreds of individual protest deadlines sounds like a full-time job, you’re not wrong. For importers who’d rather convert this administrative burden into a single transaction, claim assignment through institutional buyers provides an alternative.

You sell your validated claims — regardless of liquidation status — for immediate, non-recourse payment within 14-21 business days. The buyer takes on all deadline management, protest filings, CAPE processing, and government risk. You get paid and move on.

This is particularly attractive for entries approaching their protest deadlines, where the time pressure adds urgency. The government filing vs. immediate capital comparison helps you evaluate whether immediate capital makes sense for some or all of your portfolio.

The Bottom Line

The 180-day protest window is the most time-sensitive element of the entire IEEPA recovery process. It runs per entry, not per company. It’s a hard deadline with no extensions. And the earliest deadlines are approaching in the summer of 2026.

If you haven’t identified your liquidation dates and calculated your deadlines yet, that’s the single most important thing you can do right now. Every day of delay potentially costs you entries — and money.

An Impact Assessment maps every deadline in your portfolio, identifies which entries need immediate action, and recommends the right recovery path for each one. It’s the fastest way to get from uncertainty to a clear action plan.
