The U.S. is preparing to launch a tariff refund system on April 20, with a total of $166 billion in refunds under the recent law. However, many importers have yet to register for the refunds, and there are concerns that the process may face delays. A survey indicates that the expected relief may not substantially benefit consumers. While hedge funds anticipate significant profits from the refunds, American companies, facing financial strains due to tariffs, are looking to use their claims as loan collateral. Importers are cautioned that those who do not opt-in may face denial of their refund claims. The Customs and Border Protection (CBP) has stated that processing the returns could take 60 to 90 days.
