Atmus Filtration Drops IEEPA Case, Altering Tariff Refunds

2 min readSources: Lex Blog

Atmus Filtration dropped its IEEPA lawsuit on April 6, 2026.

Why it matters: This changes how U.S. companies handle tariff refunds, especially in international trade.

  • Atmus Filtration ended its IEEPA lawsuit on April 6, 2026.
  • Judge Eaton ordered CBP to omit IEEPA duties in tariff entries.
  • U.S. collected $130 billion in tariffs, with up to $175 billion refundable.
  • Impacts imports from Brazil and India, affecting trade compliance.

Atmus Filtration's lawsuit contesting the International Emergency Economic Powers Act (IEEPA) duties was dismissed on April 6, 2026. This dismissal influences how companies navigate tariff refunds in international trade.

Judge Richard K. Eaton of the U.S. Court of International Trade instructed U.S. Customs and Border Protection (CBP) to adjust entries without applying IEEPA duties. This could ease the burden on companies awaiting substantial refunds and streamline international business operations.

The Supreme Court earlier ruled that IEEPA does not permit presidentially imposed tariffs, lining up potential refunds that could reach $175 billion, against previous collections of $130 billion.

This shift particularly impacts imports from Brazil and India, where tariff compliance strategies may need adjustment, influencing businesses involved in these regions.

By the numbers:

  • $130 billion — Tariffs collected under IEEPA.
  • $175 billion — Estimated potential refunds.

Yes, but: Companies must still ensure compliance with evolving trade laws despite tariff changes.

What's next: Close monitoring of CBP's tariff entry adjustments is anticipated.
