FedEx was sued in federal court on Friday on behalf of customers seeking refunds from the global shipping company after the U.S. Supreme Court ruled this month that President Donald Trump unlawfully imposed billions of dollars in emergency tariffs on imported goods. The proposed class action in the federal court in Miami, Florida, seeks compensation for potentially millions of shippers who paid import duties and related fees on products that they said should have entered the United States duty-free. FedEx said in a statement on Friday: “If refunds are issued to FedEx, we will issue refunds to the shippers and consumers who originally bore those charges.”
