Country-specific duties now apply to over 70 partners and core commodities, from copper and steel to agricultural inputs, raising the average U.S. tariff to 18.3%, the highest since 1934. For U.S.-based businesses and importers, decisive action is essential to protect margins, cash flow, and compliance.
