US Commerce Secretary Howard Lutnick signaled he doesn’t expect a reprieve on 25% tariffs for steel and aluminum imports scheduled to take effect on Wednesday. The levies, ordered by U.S. President Donald Trump in February, include imports from Canada and Mexico — which are among the top foreign suppliers — and apply to finished metal products, too. U.S. steelmakers have urged Trump to resist exemptions to the tariffs, which risk hitting US companies that use aluminum and steel. Administration officials have said the policy is aimed at cracking down on efforts by countries including Russia and China to bypass existing duties. Last week, Trump imposed sweeping tariffs on imports from Canada and Mexico but later walked back some of the changes — offering a one-month reprieve to automakers and then expanding that pause to all imported goods covered by the free-trade agreement between the US, Canada and Mexico.
