Transport equipment alone accounts for nearly half of all manufacturing foreign direct investment flowing into Mexico. But here's the number that tells the more interesting story: non-automotive manufacturing exports surged more than 12% cumulatively through 2025, while automotive faced contraction from targeted US tariffs. By mid-2025, non-automotive manufacturing represented 62% of total exports — the highest share since 2009.

In other words, the automotive story everyone knows is still true, but it's no longer the whole story. Ranking manufacturing companies in Mexico by industry today means looking well beyond the auto sector, into electronics, aerospace, medical devices, and consumer goods that are quietly becoming just as important to the country's industrial identity.

This guide breaks the landscape down sector by sector, so you can see exactly where the real strength lies — and where the fastest growth is actually happening.

In this guide, you will learn:

• How Mexico's manufacturing sectors rank by investment, scale, and growth trajectory

• Which companies lead each major industry vertical

• How the regional geography maps to sector specialization

• Common mistakes companies make when assuming one sector's dynamics apply to another

• How to evaluate which sector-region combination fits your business

Ranking Mexico's Manufacturing Sectors

1. Automotive and Transport Equipment — Still the Heavyweight

Automotive remains the largest single category, capturing close to half of all manufacturing FDI. Japanese auto suppliers alone have committed an estimated $18 billion to expansion, concentrated in states like Aguascalientes and Guanajuato, with growing emphasis on electromobility and lightweight materials for next-generation vehicles.

Leading players: Grupo Industrial Saltillo supplies critical automotive components feeding directly into North America's vehicle supply chain, while major global automakers including General Motors, Ford, and Volkswagen maintain significant production facilities across the country.

Where it's concentrated: Nuevo León, Guanajuato, Aguascalientes, and the broader Bajío region.

2. Electronics and Semiconductors — The Fastest Riser

Electronics exports grew rapidly through 2025, helping cement Mexico's position as Latin America's leader in high-tech manufacturing exports. Jalisco alone now hosts roughly 70% of the country's semiconductor establishments.

Leading players: Foxconn's $900 million AI server assembly plant near Guadalajara, built to manufacture systems for major US technology clients, represents one of the clearest signals of how far this sector has matured. Intel, Texas Instruments, Infineon, and NXP Semiconductors all maintain assembly, testing, or packaging operations in the country.

Where it's concentrated: Jalisco (especially around Guadalajara), Baja California, and Coahuila.

3. Aerospace — Small Footprint, Outsized Growth Rate

Aerospace doesn't carry the sheer volume of automotive or electronics, but it recorded some of the strongest growth rates among all manufacturing verticals recently. It benefits from certified industrial clusters and a steadily growing pipeline of specialized engineering graduates.

Leading players: Concentrated aerospace clusters in Querétaro have attracted component manufacturers and system integrators serving major global aircraft programs, supported by a certified ecosystem that took years to build and is difficult for competing regions to replicate quickly.

Where it's concentrated: Querétaro, Sonora, and Chihuahua.

4. Medical Devices — Quiet Consistency

Medical device manufacturing doesn't generate the same headlines as AI server plants, but it represents one of the most consistent, quality-driven segments of Mexico's industrial base, built on decades of experience serving strict US regulatory requirements.

Leading players: Ciudad Juárez and Baja California host a dense concentration of medical device manufacturers benefiting from established quality-compliance track records and proximity to US regulatory and distribution infrastructure.

Where it's concentrated: Ciudad Juárez and Baja California.

5. Food, Beverage, and Consumer Goods — The Domestic Giants

This sector looks different from the others because its biggest players are homegrown Mexican multinationals with global reach, rather than foreign manufacturers using Mexico as a production base.

Leading players: Grupo Bimbo, the world's largest bakery products manufacturer, operates in more than 30 countries from its Mexican headquarters. Sigma Alimentos leads in refrigerated and frozen food processing with sophisticated cold-chain infrastructure. Grupo Modelo and Arca Continental dominate beverage manufacturing and bottling at massive scale.

Where it's concentrated: Distributed nationally, with major hubs in central Mexico.

6. Textiles and Light Manufacturing — The Comeback Story

This sector is experiencing a genuine revival, driven partly by deliberate government policy targeting Chinese textile imports and setting domestic production targets to cover a larger share of national consumption in textiles, footwear, furniture, and toys.

Where it's concentrated: Central and southeastern Mexico, with growing activity as policy incentives take effect.

Actionable takeaway: Don't evaluate Mexico's manufacturing landscape as a single, uniform market. Each sector has its own growth trajectory, regional concentration, and competitive dynamics — treat your sector-specific research as seriously as your overall Mexico strategy.

How the Sectors Compare

Common Mistakes When Evaluating Sectors

• Applying automotive-sector assumptions to other industries. Automotive supply chains in Mexico are decades old and deeply established. Electronics and aerospace clusters, while maturing quickly, have different supplier depth and talent availability — don't assume the same lead times or supplier density.

• Ignoring regional specialization within a sector. Not all automotive clusters are equal — a supplier specializing in EV components may find more relevant infrastructure in different states than a traditional combustion-engine parts manufacturer.

• Underweighting homegrown Mexican companies. Companies like Grupo Bimbo and Cemex aren't just domestic players — they're globally competitive manufacturers with expertise worth studying, regardless of whether you plan to compete with or partner alongside them.

• Assuming every sector benefits equally from USMCA. Automotive faces the most direct and complex tariff exposure of any sector under current trade tensions, while other categories may be less affected by the specific policy disputes dominating headlines.

Real-World Scenario: Choosing the Right Sector Cluster

An aerospace component supplier based in the southeastern US was evaluating a move to Mexico, initially drawn to Nuevo León because of its overall industrial scale and name recognition. After a closer sector-specific evaluation, they realized their component category — precision-machined parts for aircraft systems — actually had far deeper supplier density and a more relevant talent pipeline in Querétaro's certified aerospace cluster.

Choosing the less obviously "famous" region turned out to be the right call. Their onboarding time was shorter because local technicians already had direct experience with aerospace-grade tolerances, and their proximity to other aerospace suppliers meant faster access to specialized subcomponents they'd previously had to import. The broader lesson: the biggest, most talked-about industrial hub isn't automatically the right fit — the region that specializes in your specific sector usually outperforms the one that's simply the largest overall.

Expert Tips for Navigating Sector-Specific Manufacturing in Mexico

• Research your specific sector's regional cluster, not just Mexico's overall industrial reputation.

• Study the established local players in your industry, even if you don't plan to partner with them directly — their presence signals supplier depth and talent availability.

• Understand your sector's specific tariff exposure, since automotive, electronics, and other categories face different trade policy dynamics.

• Visit multiple regional clusters before choosing, since sector specialization can matter more than a state's overall industrial reputation.

• Track sector-specific growth data, not just Mexico's national FDI totals, when making location decisions.
