The U.S. Commerce Department has added 407 product categories to the existing 50% tariffs on steel and aluminum, dramatically broadening duties that were first imposed in 2018. Effective immediately, the levies now reach consumer and industrial goods such as motorcycles, baby seats, tableware, wind turbines, mobile cranes, bulldozers, railcars and a wide array of auto parts, chemicals and furniture components. Importers received little advance notice, and the tariffs also apply to goods already en route to U.S. ports. Analysts estimate the expansion lifts the value of imports subject to the metal tariffs to about $320-$328 billion a year, roughly six times the level seven years ago. The Commerce Department said the action is meant to close loopholes and deter circumvention, while steelmaker Cleveland-Cliffs praised the move as critical for domestic producers. Customs brokers and logistics firms, however, warned that the sudden rule change adds compliance complexity and could feed cost-push inflation. In a related development, major U.S. electrical-wire manufacturers Southwire and Berkshire Hathaway-owned Cerro Wire have raised list prices by roughly 5% only weeks after President Trump spared refined copper imports from any duties. Industry consultants said the tariff structure gives domestic processors greater pricing power, suggesting American consumers may face higher costs even as benchmark copper prices have fallen.
