The U.S. government appealed on June 2, 2026, a court decision that had ordered it to repay approximately $166 billion in duties unduly levied from over 330,000 importers. These duties, imposed by President Donald Trump as part of his economic policy aimed at reshoring industries, were overturned in February by the Supreme Court, which ruled that the president had exceeded his constitutional powers. Although the Customs and Border Protection (CBP) agency announced it had begun reimbursements, the government's appeal could potentially delay this process. President Trump had previously announced the establishment of new 10% tariffs for a limited period and had ordered investigations into 70 countries to potentially reintroduce surcharges.
