Supreme Court Invalidates IEEPA Tariffs — Refund Process Still Pending

Supreme Court Decision on IEEPA Tariffs

On February 20, 2026, the United States Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not provide legal authority to impose import tariffs. The Court confirmed that tariff authority rests with Congress and cannot be derived from IEEPA.

This decision directly impacts tariffs imposed solely under IEEPA authority, including certain reciprocal and emergency-based duty measures.

What the Ruling Changes

The Supreme Court decision means:

  • IEEPA-based tariffs are no longer legally enforceable.
  • U.S. Customs and Border Protection (CBP) has ceased collecting IEEPA duties on new entries.
  • Chapter 99 tariff numbers tied exclusively to IEEPA authority are no longer active in ACE for current filings.

The ruling does not affect duties imposed under other statutory authorities such as:

  • Section 232 (national security tariffs)
  • Section 301 (trade remedy tariffs)
  • Section 122 (balance of payments authority)
  • Anti-dumping or countervailing duties

No Official Refund Process Has Been Announced

Although the Supreme Court invalidated IEEPA tariff authority, the decision did not establish a refund mechanism for duties previously paid.

As of now:

  • There is no automatic refund program.
  • CBP has not issued a blanket reliquidation order.
  • No dedicated IEEPA refund portal exists.
  • No formal nationwide reimbursement directive has been published.

The legal ruling addresses authority going forward. The administrative process for recovering previously paid duties remains separate and has not yet been formally defined.

What Importers Should Monitor

Importers that paid IEEPA duties should:

  • Review historical entries where IEEPA Chapter 99 numbers were applied.
  • Confirm entry liquidation status.
  • Monitor CBP Cargo Systems Messaging Service (CSMS) updates.
  • Watch for Federal Register notices outlining refund procedures.
  • Consult customs professionals before initiating corrective filings.

Until CBP publishes official guidance, refund eligibility and process remain under administrative development.

Why This Matters for U.S. Importers

IEEPA tariffs created substantial cost exposure across industries including manufacturing, automotive, consumer goods, and industrial supply chains. While the Supreme Court ruling removes the legal basis for those duties moving forward, the lack of a formal refund process leaves prior collections unresolved.

Importers should approach this development cautiously and rely only on official CBP communications when determining next steps.

Ongoing Trade Compliance Developments

Trade policy continues to evolve rapidly. Businesses should ensure that:

  • Chapter 99 classifications are verified for current entries.
  • Section 232 and Section 301 pairings remain properly declared.
  • Reciprocal or emergency tariff references are reviewed in light of the ruling.

Staying informed is critical to avoiding improper duty exposure or missed recovery opportunities.
