US and Mexico Begin Trade Talks on Automotive Content Rules

• The U.S. is proposing new automotive rules requiring a specific minimum percentage of U.S. content in Mexican-built vehicles, a significant shift from current USMCA rules that require 40-45% of vehicle value from higher-wage North American factories
• USTR negotiators are pushing for 'melted and poured' steel requirements for preferential tariff treatment and want Mexico to match U.S. tariffs on steel imports from outside North America to reduce Chinese steel components entering the region
• The negotiations cover nearly $1.6 trillion in annual trilateral trade, with the U.S. maintaining tariffs on Mexican and Canadian goods but potentially at preferential rates compared to other countries

US-Mexico Trade Talks Target Stricter Automotive Content Rules

The United States and Mexico began formal negotiations on May 28 to revise the USMCA trade agreement, with Washington pushing for significantly stronger regional content requirements for automotive manufacturing.

Key Demands:

The U.S. Trade Representative is proposing a new U.S.-specific minimum content threshold for vehicles built in Mexico, marking a major shift from current rules. While the exact percentage remains undisclosed, this represents a departure from USMCA's existing 40-45% requirement for higher-wage factory content (primarily U.S. or Canadian production).

Additional U.S. demands include:

• Requirements for "melted and poured" North American steel to receive preferential tariff treatment
• Matching tariffs on non-North American steel imports across both countries

Market Context:

The talks occur against the backdrop of Trump administration tariffs—25% on autos and auto parts, and 50% on steel, aluminum, and copper—effectively ending three decades of duty-free North American trade. USTR Jamieson Greer confirmed that at least some tariffs on Mexican and Canadian industrial goods will remain, though potentially at preferential rates.

Canada is currently excluded from negotiations, which are scheduled through late July. The USMCA underpins nearly $1.6 trillion in annual trilateral trade.

Industry Impact:

Steel tube maker Zekelman Industries CEO Barry Zekelman supports the proposed steel requirements, arguing they would reduce Chinese steel component flows into Mexican manufacturing. Trade expert Dan Ujczo expects the eventual agreement will provide Mexico and Canada "the most preferential access to the United States" while strengthening protections against non-market economies like China.

The negotiations aim to boost U.S. manufacturing content while maintaining North American supply chain integration.
