Mexican Suppliers and Factories Directory: 500+ Manufacturers by Process

Looking for Mexican suppliers usually starts with a search, a trade show list or a contact who knows someone. A directory sorted by process is faster. Suconex lists more than 500 manufacturers in Mexico across 16 processes, from CNC machining to furniture, packaging and rubber. This guide shows how many suppliers there are in each process, where they are, what the directory can and cannot tell you, and how to go from a long list to 8–12 companies worth quoting.

TL;DR

• Suconex lists more than 500 manufacturers in Mexico in 16 process categories. Many suppliers appear in more than one.
• The largest categories are machining & CNC and metal forming (more than 200 each), then wood & furniture and welding (more than 120 each) and steel structures (about 100).
• Nuevo León leads metal forming, welding, steel structures and surface finishing; Baja California leads machining; Chihuahua leads furniture.
• A directory gives you a long list. Check every supplier yourself before you place an order.

At a glance

Counts change as companies join or edit their profiles. The suppliers page always shows the live numbers.

Suppliers by process

A supplier that machines, welds and paints is counted in all three categories, so the rows add up to more than the total. For the small categories, the directory is a starting point; ask us to search beyond it.

Where the suppliers are

Four regions come up again and again:

• Northeast (Nuevo León, Coahuila). Monterrey and Saltillo. Strong in sheet metal, stamping, welding, steel structures and finishing, close to the Laredo and Pharr crossings. Start with metal forming in Nuevo León.
• Northwest (Baja California, Sonora). Tijuana and Hermosillo. The most machining shops in the directory, plus tooling and plastics, close to California and Arizona. See CNC machining in Baja California.
• North-central (Chihuahua). Chihuahua City and Ciudad Juárez. Leads furniture and is strong in machining, welding and finishing, close to El Paso.
• Bajío and center (Querétaro, Guanajuato, San Luis Potosí, Jalisco, Puebla, Estado de México). Machining, forming and furniture, further from the border. Learn more about the Bajío.

Each category page shows the median road distance from its suppliers to the nearest US truck crossing. For welding and surface finishing it is about 360 km; for machining and metal forming it is about 670 km.

What the directory can and cannot tell you

It can tell you:

• which processes and services each company lists, such as CNC turning, laser cutting, powder coating or upholstery;
• where the plant is, and roughly how far it is by road from the nearest US truck crossing;
• company size and languages, when the company has filled them in (company size is listed on only part of the profiles);
• the company's own description of what it makes and for whom.

It cannot tell you:

• current capacity, lead time or price. Only a quote gives you those;
• whether a certification is valid. Profiles show what the company says; check certificates with the issuing body;
• quality, financial health or how the company handles problems. That takes samples, references and a visit.

From long list to shortlist in 6 steps

1. Define the part. Drawing, material, tolerances, finish, annual volume and target price. Without this, every supplier looks like a fit.
2. Filter by process, then by state. Use the category and state pages. If you need two processes, such as machining and anodizing, look for suppliers that list both, or plan a finishing partner nearby.
3. Read each profile. Drop companies whose description does not match your part or industry. Note the distance to the border crossing you use.
4. Shortlist 8–12 companies. Fewer than that, and you may not get three serious quotes. More than that, and you cannot follow up properly.
5. Send one clear RFQ. The same package to all, with a deadline. See RFQ and MOQ.
6. Vet before you pay. Check tax status, certificates, references and the plant itself. Our supplier vetting checklist shows how.

US duties on goods from Mexico (as of October 29, 2026)

Last checked: October 29, 2026. Sources: the official US government documents listed under Sources (USTR, CBP, USITC).

• USMCA. Goods that qualify for USMCA and are entered duty-free pay no 10% Section 301 duty and no merchandise processing fee.
• 10% Section 301. Since July 24, 2026, other products of Mexico pay an extra 10% (HTS 9903.05.55). It does not apply to goods already subject to Section 232.
• Section 232 metals. Many steel, aluminum and copper articles and their derivatives pay 50% or 25% on the full value, in addition to USMCA rates. Upholstered wooden seats and kitchen cabinets and vanities pay 25% under Section 232 for wood.

Which rule applies depends on the HTS code of each part. For a detailed guide, read US border duties on parts from Mexico, and confirm with your customs broker before each new product ships.
