What Is Liquidation in Customs? Why It Determines Your Refund Path

If there’s one customs concept you need to understand for IEEPA tariff recovery, it’s liquidation. This single word determines which refund path is available to you, what your deadline is, and how much your recovery will cost. And yet most importers have never heard of it.

Liquidation is when CBP (U.S. Customs and Border Protection) officially finalizes your import entry. Think of it as the government closing the books on a specific shipment. Before liquidation, the entry is open and can be corrected easily. After liquidation, it’s officially done — and changing it requires a formal challenge.

In the context of IEEPA tariff refunds, every single one of your entries falls into one of two buckets: liquidated or unliquidated. Which bucket it’s in determines everything about how you get your money back. Let’s walk through it.

Liquidation: The Basics

When your customs broker files an entry for an import shipment, you pay estimated duties upfront. At that point, CBP hasn’t actually verified anything — they’re accepting your broker’s classification, your declared value, and your calculated duty amount on a provisional basis. Your goods are released, and you go about your business.

Behind the scenes, CBP reviews the entry. They may check the classification, verify the value, compare your entry against intelligence databases, or flag it for examination. This review process takes time — months, in most cases.

Eventually, CBP makes a final determination. They either accept the entry as filed or make changes (adjusting the classification, the value, or the duty rate). This final determination is called liquidation.

When an entry liquidates, CBP either:

• Accepts it as entered — your estimated duty deposit was correct, and no further action is needed.
• Assesses additional duty — you owe more than you originally paid.
• Issues a refund — you paid more than the final calculation requires. (This is the scenario for IEEPA entries.)

The liquidation event is posted publicly on a Customs Bulletin and, more practically, updated in the ACE system. Your broker should be monitoring for liquidation events on your entries.

The Timeline: When Does Liquidation Happen?

Under normal circumstances, CBP has 314 days from the date of entry to liquidate. That’s roughly 10-11 months. If CBP doesn’t take action within that period, the entry “liquidates by operation of law” — meaning it’s automatically finalized as entered.

However, CBP can extend the liquidation period. They can extend it once for up to one year beyond the original 314 days, and they can suspend liquidation indefinitely under certain circumstances (such as pending litigation or investigation).

For IEEPA entries specifically, CBP has been using suspension of liquidation in some cases — particularly after the Supreme Court ruling created uncertainty about how to finalize entries that included invalidated tariff codes. Suspended entries haven’t been liquidated yet, which is actually good news for your recovery — they can be corrected through the simplest and fastest path.

Here’s the typical timeline for an IEEPA-period entry:

If your February 2025 entry liquidated in December 2025, your 180-day protest window closes around June 2026. That’s approaching fast.

Why Liquidation Status Is Everything for IEEPA Recovery

The four recovery paths for IEEPA refunds are directly tied to liquidation status. Let’s map them:

Unliquidated Entries: The Fast Lane

If an entry hasn’t been liquidated yet, your customs broker can file a Post-Summary Correction (PSC) through the ACE system. The PSC removes the IEEPA tariff lines (HTS 9903.01 and 9903.02 codes) from the entry, and CBP recalculates the duties without them.

Why this is the best path:

• Fastest processing time (days to weeks)
• Lowest cost (standard broker fee for filing the correction)
• No legal fees required
• No adversarial process — you’re correcting an entry before CBP finalizes it

Which entries might still be unliquidated:

• Entries filed after approximately April-May 2025 (giving 314 days to reach April 2026)
• Entries where CBP has suspended liquidation
• Entries under any extended liquidation period

As of April 2026, entries filed in the latter half of 2025 and early 2026 are most likely still unliquidated. But don’t assume — check your ACE data or ask your broker to verify.

Liquidated Within 180 Days: The Protest Path

If an entry has been liquidated, your next option is a formal protest under 19 U.S.C. Section 1514. You have exactly 180 days from the date of liquidation to file a protest challenging CBP’s assessment of duties.

How it works:

• Your broker or trade attorney files a protest with CBP, arguing that the IEEPA duties were unlawful (which is now settled law after the Supreme Court ruling).
• CBP reviews the protest and either grants it (reliquidating the entry without IEEPA duties) or denies it.
• If denied, you can escalate to the Court of International Trade.
• If CBP doesn’t respond within two years, or within 30 days of an accelerated disposition request, the protest is deemed denied.

The deadline is absolute. If an entry liquidated on December 1, 2025, the 180-day window closes on May 30, 2026. Miss that date by one day and you’ve lost the protest option for that entry.

Cost: Higher than a PSC. Broker fees for protest filing, potential legal fees if the protest is complex or if you want attorney review.

Liquidated Beyond 180 Days: CIT Litigation

If an entry has been liquidated and the 180-day protest window has passed, the only remaining government recovery path is litigation in the Court of International Trade (CIT). This requires a trade attorney admitted to the CIT bar and involves a formal legal proceeding.

Why this is the last resort:

• Most expensive path (attorney fees, court costs)
• Longest timeline (12-24 months or more)
• Requires active legal representation

The good news is that the legal argument is strong — the Supreme Court has already ruled that IEEPA tariffs are invalid. But the procedural path is more burdensome than a PSC or protest.

Claim Assignment: Any Status

Regardless of liquidation status, you can also explore claim assignment — converting your refund claim into immediate capital by assigning it to an institutional buyer. This option works for unliquidated entries, protested entries, and even entries in litigation. The buyer assumes the processing risk and timeline in exchange for a discount on the claim value.

How to Check Your Liquidation Status

You have several ways to determine the liquidation status of your IEEPA entries:

Method 1: Ask Your Customs Broker

The fastest approach. Your broker can check liquidation status in ACE for all entries filed under your importer number. Ask them for a liquidation status report covering the entire IEEPA period (February 2025 through February 2026).

Method 2: Check ACE Directly

If you have direct access to CBP’s ACE Secure Data Portal, you can view liquidation dates for your entries. Look for the “Liquidation Date” field in your entry summary data. If the field is blank or shows “Unliquidated,” the entry is still open.

Method 3: Customs Bulletin

CBP publishes liquidation notices in the weekly Customs Bulletin. This is a public record, but it’s not practical for monitoring hundreds of entries — it’s more of a legal formality than a useful tool for individual importers.

Method 4: Impact Assessment

When you request an Impact Assessment, we pull your complete entry data and map every entry to its liquidation status. This gives you a comprehensive view in one step — no need to chase individual entry statuses yourself.

The Liquidation Suspension Question

Since the Supreme Court’s IEEPA ruling, there’s been significant activity around liquidation suspension. Here’s what you need to know:

CBP has the authority to suspend liquidation of entries affected by the ruling. This is actually helpful for importers because it keeps entries in the “unliquidated” category, preserving access to the PSC path (the fastest and cheapest recovery option).

The CIT’s March 4 order plays a role here too. The order directed CBP to process refunds, and some interpretations suggest that CBP should not be liquidating IEEPA entries with the invalidated tariff lines still attached — they should either suspend liquidation or liquidate without the IEEPA duties.

In practice, the situation varies. Some entries have been liquidated with IEEPA duties included (requiring protests). Some have been suspended. Some have been liquidated without IEEPA duties (which would mean the refund is processed automatically). The inconsistency is a result of CBP processing a massive volume of entries across multiple ports.

Your action: Don’t wait to find out what happened to your entries. Check now. If they’re liquidated, start the protest process immediately. If they’re unliquidated or suspended, file PSCs. If you’re not sure, ask your broker or request an assessment.

Liquidation and Interest: The Clock Is Running

Here’s a detail that makes liquidation timing even more important: statutory interest under 19 U.S.C. Section 1505(c).

When CBP refunds overpaid duties, it owes interest from the date the duties were deposited to the date the refund is issued. The interest rate is set quarterly by the Treasury Department and has been running at approximately 4-5% annually.

This means every day that passes between when you paid the IEEPA duty and when you receive the refund, interest accrues. On a $500,000 IEEPA exposure, that’s roughly $55-70 per day in interest. Over a full year, it’s $20,000-$25,000.

The interest accrual is a silver lining to CBP’s slow processing — but only if you actually file for the refund. Interest doesn’t accrue on claims you haven’t submitted. File early, and the interest accumulates in your favor while CBP processes the refund.

Real-World Scenarios: Liquidation in Action

Let’s walk through three scenarios to make this concrete:

Scenario 1: The Well-Positioned Importer

Company A imports $2 million in goods from Vietnam monthly. They started paying IEEPA tariffs in April 2025 (after Liberation Day). Their entries from April through September 2025 have been liquidated. Their entries from October 2025 through February 2026 are still unliquidated.

Recovery plan:

• File PSCs for the October 2025 - February 2026 entries (unliquidated) — fastest recovery.
• File protests for the April - September 2025 entries (liquidated, but within the 180-day window, assuming liquidation occurred in February-July 2026).
• Total estimated claim: approximately $4.8 million in IEEPA duties plus interest.

Scenario 2: The Deadline-Pressured Importer

Company B imports electronics from China. Their earliest IEEPA entries from February 2025 liquidated in December 2025. The 180-day protest window for those entries closes in June 2026 — just weeks away.

Recovery plan:

• Immediate priority: file protests for the February - April 2025 entries before the windows close.
• File PSCs for any unliquidated entries.
• Consider accelerated disposition requests to speed up protest processing.
• Total estimated claim: depends on volume, but the urgency is real regardless of size.

Scenario 3: The Late Discoverer

Company C didn’t realize they had IEEPA exposure until now. Some of their 2025 entries have already liquidated and are past the 180-day protest window.

Recovery plan:

• PSCs for unliquidated entries (still available).
• Protests for liquidated entries still within the window.
• CIT litigation for entries outside the window (more expensive but still viable).
• Consider claim assignment for the portfolio if the litigation timeline doesn’t work with their cash flow needs.

Each scenario illustrates why knowing your liquidation dates isn’t optional — it’s the first thing you need to know. Review the IEEPA tariff refund glossary for any unfamiliar terms.

What to Do Right Now

Liquidation status is the single most important piece of data in your IEEPA recovery. Here’s your immediate action plan:

1. Get your liquidation data. Contact your customs broker and request liquidation status for all entries from February 2025 through February 2026.

2. Map entries to paths. Separate your entries into three categories: unliquidated (PSC path), liquidated within 180 days (protest path), and liquidated beyond 180 days (litigation path).

3. Prioritize by deadline. Any entry with a protest window closing in the next 60-90 days is your top priority. Missing the 180-day window costs you the most efficient remaining path.

4. Act on unliquidated entries immediately. There’s no reason to wait on PSCs. The sooner they’re filed, the sooner CBP processes the correction and issues the refund.

5. Get the full picture. An Impact Assessment maps every entry, every liquidation date, every deadline, and every recovery path in one comprehensive analysis. If you want to move from understanding liquidation to actually recovering your money, this is the next step.

Liquidation and the Extension Trap

There’s one more liquidation scenario that catches importers off guard: extensions and suspensions.

CBP can extend the liquidation period beyond the standard 314 days. They do this by issuing an extension notice — typically when they need more time to review the entry, when there’s a pending investigation, or when the entry is caught up in broader legal proceedings (as many IEEPA entries are).

An extension gives CBP up to one additional year to liquidate. A suspension can keep the entry open indefinitely. Both of these scenarios actually work in your favor for IEEPA recovery, because:

• Extended or suspended entries are still unliquidated, meaning the PSC path (fastest, cheapest) remains available.
• There’s no protest window ticking because the entry hasn’t been finalized yet.
• Your statutory interest continues to accrue, increasing your total refund.

The trap is not knowing the extension exists. If you assumed your February 2025 entry liquidated in December 2025 and filed a protest, but it was actually extended and is still unliquidated, you may have taken a more complex path than necessary. Always verify the actual liquidation status rather than estimating.

Your broker can check extension and suspension notices in ACE. When in doubt, check rather than assume.

The Bottom Line on Liquidation

Liquidation is a technical concept, but its implications for your wallet are very concrete. The difference between filing a PSC (days, minimal cost) and pursuing CIT litigation (months, significant legal fees) comes down entirely to whether your entry has been liquidated and when.
