Overview
- Costco filed its complaint on Nov. 28 in the U.S. Court of International Trade seeking a declaratory judgment, an injunction, and a full refund of duties paid under President Trump’s IEEPA-based tariff orders.
- The company says U.S. Customs and Border Protection denied its request to extend liquidation deadlines, with some entries set to liquidate as early as Dec. 15, potentially cutting off refund rights.
- Costco asked the court to stop CBP from collecting additional duties while the Supreme Court considers the separate challenge to the IEEPA tariffs.
- On Monday, Costco moved to consolidate its case with nearly two dozen similar suits, joining companies such as Bumble Bee Foods, EssilorLuxottica, Kawasaki Motors, Revlon, and Yokohama Tire seeking to preserve refund claims.
- The Supreme Court heard expedited arguments on Nov. 5 and has not ruled; a White House spokesperson warned of significant economic consequences if the tariffs are struck down, while CBP data show importers have paid roughly $90 billion under the IEEPA regime through late September.
