Supreme Court strikes down IEEPA tariffs, triggering largest customs refund in U.S. history

Supreme Court strikes down IEEPA tariffs, triggering largest customs refund in U.S. history

Rule Changes

CBP has approved about $126 billion in refunds for tariffs the Supreme Court ruled unlawful, and a judge ordered it to reopen closed entries for importers in litigation

4 days ago: Judge orders CBP to reopen final entries for IEEPA refunds

Overview

Updated Yesterday

U.S. Customs and Border Protection has approved about $126 billion in refunds for tariffs the Supreme Court struck down in February, out of roughly $166 billion collected. The money moves through CAPE, the portal CBP built after the ruling and opened on April 20. Judge Richard Eaton has ordered the agency to reopen entries it treated as final for importers in litigation, and on October 8 he certified a class of importers who never sued.

CBP said on October 20 that a second wave of importers can now use Phase 3, the part of the system for closed entries, and that more will follow. The government asked Eaton on October 21 for more time to propose a schedule in the class case. Democratic lawmakers, including Sen. Raphael Warnock of Georgia, asked the Government Accountability Office to audit how CBP is running the refunds.

Why it matters

Businesses that paid tariffs the courts called unlawful are getting their money back; shoppers who paid higher prices likely won't see a cent.

"How extraordinary that the mightiest republic on earth, having conquered a continent, cannot manage to build a working portal — the Americans seized half a world from Mexico and Spain, yet their customs clerks are undone by a duplicate Tax ID error."

Fictional AI pastiche — not real quote.

"When a government builds a portal to return $166 billion it had no lawful right to collect, and that portal promptly collapses under the weight of its own ambition — well, I have built a great many things, and I can tell you that the surest sign of poor engineering is a structure that fails precisely when it is most needed."

Tap a bar to jump to that date
  1. CAPE Phase 3 opens for finally liquidated entries

    Administrative

    CBP began taking refund claims for entries more than 80 days past liquidation, covering about $11.4 billion in duties. Only plaintiffs who gave CBP their importer-of-record numbers by July 31 can use it.

  2. CBP filing: $1.1 billion in refunds held for missing bank details

    Administrative

    In its latest sworn declaration to the Court of International Trade, CBP said 20,362 refunds worth about $1.1 billion were unpaid because importers had no bank account on file. The agency had approved about $126 billion in refunds, current through Oct. 2.

  3. CBP reports $122 billion sent to Treasury for refunds

    Administrative

    In a September 11 report, CBP said about $122 billion in refunds, including interest, had been completed, certified, and sent to the Treasury for disbursement. Some 286,044 CAPE declarations had been received; more than 20,000 refunds worth $1.3 billion were held up by missing banking details.

  4. CBP reports $100 billion in refunds processed

    Administrative

    CBP said roughly $100 billion in duties and interest had been processed and sent to the Treasury, with about $128.68 billion in the system; more than 252,000 refund declarations had been submitted as of July 31.

  5. First refund payments reach importers

    Administrative

    Importers began receiving tariff refund checks for duties the Supreme Court struck down in February, weeks after CBP launched the CAPE portal.

  6. CAPE refund portal goes live

    Administrative

    CBP launches Phase 1 of the Consolidated Administration and Processing of Entries (CAPE) system, enabling importers to file refund claims covering $127 billion in IEEPA duties through the ACE Secure Data Portal.

  7. CAPE portal hit by technical glitches at launch

    Administrative

    Within hours of the 8:00 AM launch, the CAPE portal displayed 'high volume' error messages, produced duplicate Tax ID errors, and left some importers unable to access their accounts. Trade attorneys warned that delays from technical failures can cause importers to permanently lose refund eligibility. The Main Street Alliance called for the administration to streamline the process for small businesses without legal resources.

  8. Over 56,000 importers register for refunds

    Administrative

    CBP reports that 56,497 importers have enrolled in the automatic refund system, representing 82% of entries with IEEPA duty payments.

  9. CBP announces plan to build refund system without requiring lawsuits

    Administrative

    CBP announces it will create a centralized electronic refund process, sparing importers from having to file individual lawsuits to reclaim duties.

  10. Trump announces Section 122 replacement tariffs

    Executive Action

    Hours after the ruling, Trump announces new tariffs under Section 122 of the Trade Act of 1974, set at 15% globally — the maximum allowed. Section 122 imposes a 150-day time limit.

  11. "Liberation Day" tariffs announced

    Executive Action

    Trump signs Executive Order 14257, declaring a national emergency over the trade deficit and imposing IEEPA tariffs on nearly all countries — 10% baseline starting April 5, with higher rates for major trading partners starting April 9.

  12. Trump imposes first IEEPA tariffs

    Executive Action

    The administration publishes IEEPA-based tariffs on imports from China, Mexico, and Canada, citing the opioid crisis. It marks the first time IEEPA has ever been used to impose tariffs.

Scenarios

1

Refunds flow smoothly, importers recoup billions by summer

Likely

Discussed by: Trade law firms (Covington, Holland & Knight), CBP's own projections

If the CAPE system performs as designed and CBP meets its 60-to-90-day processing target, the bulk of Phase 1's $127 billion could be returned by July or August 2026. Phase 2 would follow for remaining entries. This outcome would provide a significant cash infusion to importers who have carried the cost for over a year, though questions remain about whether consumers who paid higher prices will see any benefit.

2

Processing bottlenecks delay refunds, importers return to court

Possible

Discussed by: Cato Institute, Morgan Lewis, trade litigation attorneys

The sheer scale — 53 million entries, $166 billion — could overwhelm CBP's systems. Compliance reviews could flag large numbers of claims. If delays stretch beyond 90 days, importers may seek court orders compelling faster action, and the CIT could impose deadlines or penalties. The 18% of entries not covered in Phase 1 remain in limbo until later phases are built.

3

Congress intervenes to restructure tariff authority permanently

Possible

Discussed by: Peterson Institute for International Economics (PIIE), Brookings Institution, Congressional Research Service

The Supreme Court ruling exposed a gap: Congress never explicitly authorized presidents to impose tariffs through emergency powers, yet presidents have broad trade authority under other statutes. Lawmakers could use this moment to either expand presidential tariff power with clearer statutory language or restrict it further. The 150-day clock on Section 122 tariffs creates a natural forcing function for congressional action by mid-July 2026.

4

Section 301 investigations replace IEEPA as the long-term tariff vehicle

Likely

Discussed by: Global Trade Alert, Duane Morris, Perkins Coie

Trump signaled that the 150-day Section 122 tariffs are a bridge to Section 301 investigations under the Trade Act of 1974, which allows tariffs in response to unfair trade practices without the time limits or rate caps. If the administration launches and concludes 301 investigations before Section 122 expires, it could reimpose tariffs at or above previous IEEPA levels on a country-by-country basis — this time on firmer legal ground.

5

Portal glitches snowball, small importers permanently lose refund rights

Possible

Discussed by: Trade attorneys cited by CBS News and Fortune; Main Street Alliance

The CAPE portal's bumpy launch — featuring high-volume errors, duplicate Tax ID failures, and multi-hour CBP hold times — could have consequences beyond inconvenience. Trade attorneys have warned that processing delays tied to technical errors can cause importers to miss filing windows and permanently forfeit refund eligibility. Small businesses without customs brokers or legal counsel face the greatest exposure, as the CSV-based filing process assumes substantial trade compliance expertise.

6

Class actions push some refund money back to consumers

Uncertain Resolves by End of 2027

Discussed by: Plaintiffs' attorneys; BBC News

Individuals have filed federal class actions against Ray-Ban maker EssilorLuxottica and FedEx, plus one against Costco in the Western District of Washington, arguing importers who passed tariff costs to shoppers should pass refunds back. Costco says it plans to use refunds to lower prices; FedEx says it will return money to shippers; other companies have made no such pledge.

7

Final-entry ruling widens the refund pool beyond $134.7 billion

Likely Resolves by Q2 2027

Discussed by: National Law Review; Inside Trade

The October 18 order lets importers in litigation recover IEEPA duties on entries CBP had treated as final. Applied widely, it could push accepted claims beyond the roughly $134.7 billion already in the CAPE pipeline.

8

Certified class wins a refund order for importers who never sued

Possible Resolves by Q2 2027

Discussed by: Troutman Pepper Locke; Davis Wright Tremaine

Judge Eaton certified the class on October 8 and said he hoped it would lead to reliquidation of all the entries. Certification alone orders no refunds, the government is expected to appeal, and a classwide order would open payments on entries that are closed today.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

March 1998

United States v. United States Shoe Corp. — Harbor Maintenance Tax (1998)

The Supreme Court unanimously ruled that the Harbor Maintenance Tax — a 0.125% ad valorem charge on cargo shipped through U.S. ports — violated the Export Clause of the Constitution when applied to exports. The government had collected the tax from exporters for over a decade before the Court struck it down.

Then

The government was required to refund all unlawfully collected payments to exporters, including interest. A claims process was established through Customs.

Now

The case established the principle that the government must return unlawfully collected trade-related payments in full. It became the key precedent cited by importers seeking IEEPA tariff refunds.

Why this matters now

This is the closest legal precedent to the current situation — a Supreme Court ruling invalidating a trade-related government charge and triggering a refund process through Customs. However, the IEEPA refund dwarfs it in scale: $166 billion versus roughly $730 million.

June 1952

Youngstown Sheet & Tube Co. v. Sawyer — The Steel Seizure Case (1952)

During the Korean War, President Truman ordered the federal seizure of U.S. steel mills to prevent a strike that he said threatened national security. The Supreme Court ruled 6-3 that the president lacked authority to seize private property without congressional authorization, even during a national emergency.

Then

The steel mills were returned to their owners. The steelworkers went on strike for 53 days.

Now

Justice Jackson's concurrence established the foundational framework for analyzing presidential power — a three-tier test that courts still use today, including in the IEEPA tariff cases.

Why this matters now

Both cases involve a president invoking emergency authority to take extraordinary economic action that the Supreme Court ultimately found exceeded executive power. The IEEPA ruling echoes Youngstown's core holding: emergency declarations do not give the president powers that Congress has not granted.

June 1930 – June 1934

Smoot-Hawley Tariff Act and the Reciprocal Trade Agreements Act (1930–1934)

Congress passed the Smoot-Hawley Tariff Act in 1930, raising duties on over 20,000 imported goods despite a petition from 1,028 economists urging a veto. Trading partners retaliated, and U.S. exports fell 61% in three years. In 1934, Congress passed the Reciprocal Trade Agreements Act, delegating tariff-setting authority to the president to negotiate reductions — the origin of modern presidential trade authority.

Then

Global trade collapsed. Senator Smoot and Representative Hawley both lost their seats.

Now

Congress effectively surrendered direct control over tariff rates, creating the broad presidential trade authority that persists today — and that the IEEPA case now constrains.

Why this matters now

The IEEPA ruling is the most significant judicial check on presidential tariff authority since Congress delegated that power 90 years ago. The 1934 delegation created the system; the 2026 ruling defined its outer boundary.
