The president signed executive orders today offering a monthlong exemption, until April 2, for all goods covered under the U.S.-Mexico-Canada trade agreement, which includes most U.S. imports from those countries. About 10 percent of Mexico’s exports to the U.S. fall outside the U.S.M.C.A. trade agreement, according to one economist.

New 25% trade tariffs on goods from Canada and Mexico went into effect early Tuesday after President Donald Trump declined to extend a 30-day pause in a move the president says aims to quell the flow of illegal drugs like fentanyl into the U.S. The new assessments also include a 10% tariff on Canadian energy products.
