CryptoWorld News reports that U.S. Customs and Border Protection (CBP) said the first batch of electronic tariff refunds—set to be returned because the U.S. Supreme Court has ruled them illegal—will begin as early as May 12, involving a total of up to $166 billion in already collected tariffs to be refunded. The first electronic refund timeline published by CBP is one day later than previously estimated, but it did not provide an explanation for the one-day delay. The Supreme Court’s ruling affects far more than the refund mechanism itself. The International Emergency Economic Powers Act (IEEPA) has become a core tool of Trump’s trade policy, and the law was ruled invalid by the judiciary, meaning the government has lost one of its most flexible ways to put pressure on tariffs without needing approval from Congress. The $166 billion figure represents the cumulative amount of assessed taxes that could be challenged, making this refund one of the largest large-scale forced fiscal reversals in recent U.S. trade history.
