Trade negotiations between the United States and Mexico have stalled over steel and aluminum tariffs, with major progress now potentially delayed until after the November 3 midterm elections. People familiar with the discussions say U.S. officials, including Commerce Secretary Howard Lutnick, have pushed back against Mexico’s demands for lower tariffs. One key sticking point involves duties on products made from steel and aluminum, which Mexican officials say cover a substantial part of their economy. Financial Post said talks reportedly cooled after a U.S. counterproposal failed to address Mexico’s concerns. Mexican officials have said they want tariff relief as part of any agreement. Roberto Lazzeri, Mexico’s ambassador to the United States, acknowledged the challenges on Monday, saying, “We’re a little bit stuck on the details.” The impasse puts off hopes for a near-term agreement, leaving businesses on both sides of the border facing continued uncertainty over metals trade and broader economic ties.
