FedEx filed a lawsuit Monday in the U.S. Court of International Trade, requesting a refund for emergency tariffs imposed under the Trump administration that the U.S. Supreme Court recently deemed illegal.

According to court documents, FedEx is seeking “a full refund from Defendants of all IEEPA duties Plaintiffs have paid to the United States,” referencing tariffs imposed under the International Emergency Economic Powers Act. The company has not disclosed the total dollar amount it expects to recover.

The lawsuit names U.S. Customs and Border Protection, its commissioner Rodney Scott, and the United States of America as defendants. Neither Customs and Border Protection nor the White House immediately responded to requests for comment.

Washington, D.C.-based law firm Crowell & Moring represents FedEx in the case and directed inquiries to the company, which did not provide an immediate comment. Crowell & Moring also represents other companies, including Costco, Revlon, and EssilorLuxottica, in cases seeking refunds for IEEPA tariffs.

The lawsuit follows last week’s Supreme Court decision striking down the emergency tariffs, which had been a key element of former President Donald Trump’s trade policy, affecting shipments and imports across multiple industries. FedEx’s legal action aims to recover payments made under those now-invalidated duties.
