The $166 Billion Tariff Refund: What U.S. ImportersNeed to Know

Following a landmark 2026 Supreme Court decision overturning excessive IEEPA tariffs, billions of dollars are being refunded to U.S. importers. Find out if your shipments qualify, how the CBP's new CAPE portal works, and the critical deadlines to claim your funds.

Following a landmark Supreme Court ruling in February 2026, a historic $166 billion refund opportunity has emerged for U.S. importers. The refunds finally started flowing in May 2026, but navigating the administrative maze to claim your share requires precision and urgency. Here is what you need to know to secure the capital rightfully owed to your business.

What happened, in plain English

In April 2025, a sweeping set of tariffs was enacted under the International Emergency Economic Powers Act (IEEPA). However, in a decisive 6-3 ruling in February 2026, the Supreme Court determined that the President exceeded constitutional authority in deploying these specific IEEPA measures without adequate congressional oversight.

The immediate consequence? Customs and Border Protection (CBP) was mandated to refund all IEEPA duties collected during that period, with interest. This monumental decision affects over 330,000 importers and spans across more than 53 million individual shipments.

What's eligible — and what isn't

Not every tariff paid over the last few years is eligible for a refund. It is critical to differentiate between the qualifying IEEPA duties and other trade actions. Look closely at your CBP Form 7501 and HTS Chapter 99 codes.

Eligible

• Reciprocal tariffs (Executive Order 14257)

• Emergency tariffs on China

• Emergency tariffs on Canada

• Emergency tariffs on Mexico

Not Eligible

• Section 232 (steel/aluminum)

• Section 301 (China-specific actions)

• Section 122 (the new 10% baseline tariff)

How refunds are being processed: The CAPE system

On April 20, 2026, CBP launched the Consolidated Administration and Processing of Entries (CAPE) tool via the ACE Portal. This automated platform was designed specifically to handle the massive volume of IEEPA refund claims resulting from the Supreme Court decision.

As of late April, over 75,000 CAPE Declarations covering 11+ million entries had already been filed. CBP is currently processing these submissions through the system to ensure accuracy against internal records before issuing payments.

Phase 1: The Immediate Opportunity

CBP is handling this massive undertaking in phases. Phase 1 is currently open and applies specifically to unliquidated entries and entries liquidated within the last 80 days.

This rolling 80-day deadline is the most critical time-sensitivity factor right now. If your entries age past 80 days of liquidation without a protective action filed, your claim becomes vastly more complicated. Later phases will eventually cover reconciliation entries, drawback claims, and historically liquidated entries, but you must not wait for those phases if you have entries currently within the 80-day window.

The Trap: Protests, Interest, and Older Entries

While the CAPE system streamlines recent entries, several traps await the unwary importer:

• Formal Protests: Older entries (pre-80 days post-liquidation) require formal protests within a strict 180-day window from liquidation to preserve your rights. Miss this, and the money is likely gone forever.

• Interest Accrual: By law (19 CFR 24.36), CBP must pay interest. For corporate filers, this interest is accruing at approximately 6%. Ensure your filings correctly trigger this calculation.

• ACH and Offsets: You must have a valid ACH banking setup in ACE. Furthermore, CBP will automatically offset any approved refunds against outstanding CBP debt you may hold.

• Validation Rejections: A single typo in your data submission can lead to a validation rejection, throwing your submission out of the queue and potentially past a filing deadline while you attempt to fix it.

Why this matters for your bottom line

Whether you are in consumer goods, electronics, industrial equipment, automotive parts, or apparel, these tariffs severely compressed margins over the last year. This refund is not "found money" it is recovered capital that belongs on your balance sheet.

Consider the case of a mid-sized wine importer who effectively utilized the early days of the CAPE rollout: by acting quickly on their Phase 1 unliquidated entries, they have already received a $110,000 ACH refund, injecting critical liquidity just in time for their Q3 purchasing cycle.
