On the Dash:
- Stricter content requirements may increase vehicle production costs and put additional pricing pressure on new inventory.
- Automakers could shift their supply chains toward U.S.-based manufacturing and parts sourcing to meet updated trade rules.
- Ongoing tariffs on autos, parts, steel, and aluminum may lead to long-term volatility in vehicle pricing and dealership profit margins.
U.S. and Mexican negotiators began formal discussions on Thursday, focusing on stricter regional rules of origin for vehicles made in Mexico.
The U.S. proposal includes a new minimum threshold for U.S.-specific content in cars and trucks manufactured in Mexico, marking a significant departure from the current U.S.-Mexico-Canada Agreement (USMCA) framework, which emphasizes broader North American content rather than specific country sourcing.
Under current USMCA rules, 40% to 45% of a vehicle’s value must come from higher-wage factories in the U.S. or Canada, including essential components such as engines, transmissions, body panels, and chassis systems. Notably, these negotiations are taking place without Canada’s involvement.
The Office of the U.S. Trade Representative has scheduled three rounds of negotiations through late July, with the ongoing session in Mexico City concluding on Friday. U.S. Trade Representative Jamieson Greer stated that the administration aims to strengthen rules of origin to boost U.S. manufacturing content in North American-built vehicles.
Impact of tariffs on trade
These negotiations come alongside aggressive tariffs on imported autos, auto parts, steel, aluminum, and copper. The current tariff structure includes:
- 25% tariffs on autos and auto parts
- 50% tariffs on steel, aluminum, and copper
These tariffs have effectively ended decades of mostly duty-free trade within North America. Trade attorney Dan Ujczo has noted that negotiators still aim to preserve preferential trade access among the U.S., Mexico, and Canada despite rising tensions. Industry analysts expect the revised trade rules to include stronger protections against imports from non-market economies, such as China.
Changes in steel requirements
Steel executives have reported that U.S. negotiators plan to introduce new “melted and poured” requirements for North American steel receiving preferential tariff treatment. This would require qualifying steel products to be produced entirely within North America, aiming to close loopholes that currently allow Chinese steel to enter Mexican manufacturing operations. Additionally, U.S. negotiators are urging Mexico to align its steel tariffs with those imposed by the U.S. on imports from outside North America.
The outcome of the USMCA negotiations could greatly reshape North American automotive manufacturing and sourcing strategies, as well as vehicle pricing, if stricter content rules and tariff policies are adopted.
