Why so Many US Manufacturers Operate Factories in Mexico

US manufacturers are increasingly establishing production facilities south of the border, driven by economic advantages and strategic positioning.

From automotive giants to medical device innovators, companies across sectors are making substantial long-term commitments to Mexican manufacturing infrastructure, gradually altering North American industrial geography.

The momentum behind this migration reflects more than short-term cost considerations.

"They're making a 30-year bet, not a three-year bet," explains Jay Truesdale, CEO of Veracity Worldwide, a strategic advisory firm. "Even if your desired end customer is not fully up and running, you're going to be producing things that will have a global demand."

This perspective demonstrates how US manufacturers view Mexico as integral to their long-term competitive positioning.

Automotive sector leads manufacturing investment

The automotive industry represents the most established US manufacturing presence in Mexico.

General Motors operates four manufacturing plants across the country, while Ford maintains multiple facilities including assembly operations in Cuautitlán and Hermosillo, plus an engine plant in Chihuahua.

Tesla is planning to build a mega-plant in Mexico. CEO Elon Musk says: "The factory will be supplemental to the output of our factories in California, Texas, Berlin and Shanghai... it's about being able to build cars that are more affordable."

The project is currently paused pending trade policy clarity.

Key industry sectors operating in Mexico

Many key industry sectors are operating facilities in Mexico:

• Aerospace & Defence: Honeywell operates 11 facilities, including an automated aerospace factory in Mexicali, producing high-tech components.
• Medical Devices: Medtronic has six plants, including a Tijuana facility manufacturing pacemakers and heart valves.
• Electronics: Intel runs research and development hubs primarily in Guadalajara for advanced technology development.
• Industrial Equipment: Caterpillar and John Deere both operate manufacturing facilities for heavy machinery and agricultural equipment.
• Consumer Goods: Whirlpool maintains longstanding production facilities in cities including Monterrey.

The aerospace sector has become particularly sophisticated, with companies including Curtiss-Wright operating factories in Nogales, producing complex electronics and assemblies.

USMCA trade agreement drives growth

The US-Mexico-Canada Agreement provides the regulatory framework enabling this manufacturing migration.

The trade agreement offers duty-free access to North American markets while strengthening intellectual property protections. These are critical considerations for technology and pharmaceutical manufacturers.

Combined with Mexico's skilled engineering workforce and significantly lower labour costs, the USMCA produces a strong economic argument for nearshoring strategies.

However, there is uncertainty on the horizon, with the USMCA up for renegotiation in 2026. The Trump Administration is expected to push for a more favourable deal for the US, with Canada and Mexico likely to push back against tariffs.

Technology giants establish innovation hubs

Beyond traditional manufacturing, technology companies are establishing substantial Mexican operations.

IBM's Guadalajara facility is the global manufacturing centre for its Power Systems line, while HP and Dell Technologies both use Mexico's industrial base for hardware production and supply chain optimisation.

Recent substantial investments demonstrate ongoing confidence in Mexican manufacturing.

Humanscale, an ergonomic office furniture manufacturer, committed nearly US$30m to expand its Nogales facility in 2025, incorporating advanced high-tech manufacturing processes.

The company's leadership explained: "We chose Mexico because of its proximity to the North American market, cost efficiencies and a reliable and dedicated workforce.

“Producing the same products in the United States would not only be far more costly but very difficult in terms of hiring qualified and long-term workers."

Strategic advantages driving Mexico investment

There are a variety of advantages for US businesses when investing in Mexico:

• Proximity: reduced logistics costs and faster response times to North American customers
• Skilled labour: access to engineers and technical specialists at competitive wage rates
• Infrastructure: established maquiladora programme supporting US-Mexico production partnerships
• Cost Efficiency: significant savings on labour whilst maintaining quality standards
  
• Market Access: USMCA benefits enabling smoother North American trade.
