The US government has rolled out a system to facilitate refunds of over $166 billion from tariffs introduced by Donald Trump and later invalidated by the US Supreme Court. In February, the court struck down a broad set of reciprocal tariffs, delivering a significant setback to a central pillar of Trump's economic agenda and paving the way for repayments. On Monday, US Customs and Border Protection announced that the first phase of its refund-processing platform is now operational, allowing importers and customs brokers to begin filing claims to recover the duties they had paid.
