Costco is suing the U.S. government over Trump’s tariffs. Here’s why

Costco has filed a lawsuit against the U.S. government to secure potential tariff refunds. This action is contingent on the Supreme Court rejecting President Trump's request for broad tariff-imposing authority. The complaint, filed in the U.S. Court of International Trade, highlights uncertainty regarding businesses' ability to reclaim wrongly paid tariffs. Costco argues that the refusal by U.S. Customs and Border Protection to extend tariff calculation deadlines jeopardizes their refund rights. This move by Customs and Border Protection further complicates the situation for Costco. The retail giant is not alone, as numerous other companies are pursuing similar legal actions. Notable companies including Bumble Bee Foods and Revlon have also filed suits. The Supreme Court heard arguments on the legality of Trump's emergency powers usage for tariffs. Justices expressed skepticism during these oral arguments. The Supreme Court is considering the case on an expedited schedule but has not set a ruling date.
