Republican presidential nominee and former president Donald Trump made headlines this week during a policy roundtable in Smithton, Pa.

During the roundtable, Trump brought up Deere’s announcement earlier this year that it would be moving some production to Mexico by 2026.

He said, quote, “I’m just notifying John Deere right now: If you do that, we’re putting a 200% tariff on everything that you want to sell into the United States.” 

There’s one major roadblock to that threat, however — the United States-Mexico-Canada Agreement, signed by Trump when he was president in January 2020, which replaced the North American Free Trade Agreement. USMCA prohibits the leverage of tariffs on a range of goods, allowing companies to manufacture in Mexico and Canada and export back to the U.S. without high costs.
