The Globe and Mail reports in its Saturday edition that U.S. automakers are urging the Trump administration to stop the unpredictable expansion of steel and aluminum tariffs, warning that increased costs and uncertainty threaten investments and jobs. The Globe's Eric Atkins writes that recently, the U.S. government commenced a process to expand the list of goods subject to Section 232 tariffs, allowing stakeholders to propose additional products. A previous move in August imposed 50-per-cent tariffs on 407 imported products valued at $240-billion (U.S.). Trade groups have expressed concerns in a letter to Jeffrey Kessler at the U.S. Department of Commerce about the "sudden expansion" of tariffs, which they say is raising prices for goods that manufacturers cannot source domestically. They highlight that unpredictable trade policies are hurting investment and production planning. The letter is signed by the American Automotive Policy Council, representing companies like Ford, General Motors and Stellantis, along with the Aerospace Industries Association and over 40 other groups. "We urge the department to eliminate further unpredictable expansions and make targeted determinations with a clear nexus to national security."
