The United States has launched a $166 billion tariff refund system, allowing businesses to reclaim taxes paid on certain tariffs deemed unauthorized by a court ruling. Companies can apply for refunds, with disbursements expected within 60 to 90 days post-approval. Over 56,000 companies have registered, with potential refunds totaling $127 billion. The system primarily benefits importers and their agents, covering selected eligible tariff orders. While the move is expected to ease corporate cash flow pressures, the benefits are largely confined to businesses, as previous tariff costs were often passed to consumers. Legal challenges, including class-action lawsuits against companies like Costco, seek to extend refunds to consumers. Logistics firms such as FedEx and UPS have committed to refunding customers for duties paid on their behalf if refunded.
