Costco has joined a growing number of businesses suing the Trump administration to secure refunds if the Supreme Court invalidates the president’s global tariffs policy. The lawsuit, filed on November 28th in the U.S. Court of International Trade, was prompted by concerns over the uncertainty of refunds for companies paying duties. Costco’s lawyers said: “We need a court intervention immediately” due to Customs and Border Protection denying an extension for tariff determinations. The Supreme Court heard arguments on the tariffs on November 5th, and while lower courts have ruled against the administration, the tariffs remain in effect until a decision is made. Other companies, including Revlon and Kawasaki, have also filed similar lawsuits. The ongoing tariff policies have disrupted the retail sector, raising prices and affecting consumer purchasing power.
