After the Supreme Court invalidated Donald Trump's tariffs, an estimated 330,000 importers are eligible for refunds totaling over $166 billion. The refund process, initiated in late April, requires businesses to work with their original customs brokers to file claims electronically through the Customs and Border Protection's Ace Secure Data Portal. Although some glitches have been reported, the process is reportedly functioning better than expected, with refunds anticipated within 60 to 90 days. However, businesses must be aware of potential costs, as service providers like Supply Chain Solutions may charge fees for handling the refund claims. Additionally, any refunds received in 2026 will be taxable, impacting business owners' tax planning. Major shipping companies, including FedEx and UPS, have pledged to return these refunds to their customers, while larger brands like Amazon and Apple have yet to clarify their positions on refund distribution. This development offers a rare opportunity for businesses to reclaim funds that many initially thought would be lost in bureaucratic delays.
