The U.S. Customs and Border Protection (CBP) announced that the first batch of electronic tariff refunds, deemed illegal by the Supreme Court, will begin to be distributed as early as May 12. The total amount of tariffs to be refunded reaches as much as 166 billion dollars.

According to reports, the first batch of electronic refund times announced by CBP was one day later than previously estimated, but no explanation was given for the delay. The impact of the Supreme Court's ruling goes far beyond the refund mechanism itself. The International Emergency Economic Powers Act (IEEPA) has become a core tool of Trump's trade policy, and its judicial invalidation means that the administration lost its most flexible method of imposing tariff pressure without congressional approval. The figure of $166 billion represents the cumulative amount of taxes that may be challenged, making this refund one of the largest mandatory fiscal reversals in recent US trade history.
