Corporate merch in Silao — the heart of the Bajío automotive cluster
Industrial uniforms, plant polos, safety kits and corporate gifts for companies based in Silao, Puerto Interior, the Honda / Toyota / Mazda / GM assembly plants, the IMMEX supplier base and the tier-1 supply chain that feeds the Bajío. Invoicing in MXN with 16% IVA via CFDI 4.0 (SAT), payment complement, import pedimento and corporate purchase order handling.
Mexico's most important automotive cluster
Silao is a municipality in the state of Guanajuato that forms part of the Bajío industrial corridor — the country's most dynamic manufacturing region. The General Motors assembly plant in Silao builds the Silverado, Cheyenne and Sierra pickups; Toyota's plant began operations in 2019 with Tacoma production; Mazda operates a plant in Salamanca, 30 kilometres away. The region hosts more than 30 tier-1 suppliers, dozens of tier-2 and tier-3 vendors, and the multimodal logistics hub Puerto Interior.
Puerto Interior is Mexico's largest multimodal logistics park: 1,200 hectares with Kansas City Southern (KCSM) and Ferromex rail connections, cargo terminals, an inland customs office and dedicated manufacturing and warehousing zones. The Aeropuerto Internacional del Bajío (IATA: BJX) is 15 minutes from Silao and handles cargo and passenger flights to the United States, Europe and Asia. The formal economy runs on automotive manufacturing, multimodal logistics, IMMEX supplier operations and customs processing with pedimento.
Assembly plants, IMMEX suppliers and tier-1 networks
The Silao assembly plants — GM Silao, Toyota Mexico, plus suppliers like Continental, Brose, Valeo, Aptiv, Magna, Lear, Faurecia, Bosch, ZF, Yazaki — operate under strict quality standards (IATF 16949, ISO 9001, ISO 14001) and personnel presentation rules: area-graded uniforms (production, quality, maintenance, logistics, office), onboarding polos with biosafety QR codes, supervisor-graded vests and operator-graded polos.
IMMEX suppliers in the region handle import and export pedimentos, hold a vigente IMMEX program and demand merch with CFDI 4.0 invoicing that supports their cost accounting and tax deductions. We supply industrial polos with flame-resistant treatment (NFPA 2112 when required), ESD-graded uniforms for paint and electronics areas, and complementary PPE kits (glasses, gloves, earplugs) that comply with the NOM-017 STPS regulation.
Puerto Interior, multimodal logistics and customs
Puerto Interior hosts more than 200 logistics, manufacturing and services companies. The cargo terminals operate 24/7 with KCSM, Ferromex and the inland customs office that processes import and export pedimentos for IMMEX and foreign trade. Companies order operator-graded polos for yard staff, reflective supervisor-graded vests, identification kits with supervisor grade and operation-grade safety polos for temporary personnel.
Customs brokers, freight forwarders and 3PL (third-party logistics) operators working out of Puerto Interior order corporate merch with corporate embroidery, gift sets for international clients and polos for administrative teams. The Bajío Convention Center and Poliforum León are 25 minutes away and host industrial fairs (Expo Proveedor Industrial, Automotive Industry meetings, Farnborough aerospace) where staff merch and corporate client kits are central to the operation.
Onboarding, retention and corporate events
The Bajío operates with high turnover at the operator levels — manufacturing and logistics churn rates average 4% to 8% monthly — and plant HR departments run constant onboarding programs. We deliver onboarding kits with a corporate polo, backpack, tumbler and engraved badge, produced in runs of 50 to 500 pieces per monthly cohort. Retention programs reward tenure (5, 10, 15, 20 years) with engraved gift sets and public recognition.
Plant events — anniversaries, model launches, safety events (Safety Day), inter-area competitions, family events, sports tournaments — need their own branded merch: polos for the organising team, hydration sets, backpacks for participants, caps for tournaments and recognition kits for finalists. Internal wellness programs and diversity and inclusion events run merch with specific messages and localised embroidery. If your brief includes quantity, date and venue (plant, Puerto Interior, onboarding event, Safety Day, anniversary, IMMEX program), we'll walk through it and ground it in production.

Lead times and Bajío delivery
Our operation covers Silao, Puerto Interior, León, Irapuato, Salamanca, Celaya and the Bajío corridor. Production leaves our central workshop and arrives via road freight at Puerto Interior, Poliforum León or directly to your plant. Standard lead times: 8 to 12 business days for production plus 1 to 3 days for delivery in the Bajío.
For plant events we keep base inventory of white polos in S to XXL, reflective vests, backpacks and engraved tumblers with 3 to 5 business-day express turnaround. The Bajío supply chain is one of the most robust in the country, which lets us hit tight deadlines with consistent quality. We'll walk through it with you and adjust the flow to your plant or event calendar.
What we are not
Corp-Merch is a corporate merch, uniform and executive gift brand for businesses. We are not part of GM, Toyota, Honda or Mazda, we do not represent the IMMEX suppliers or Puerto Interior. We do not sell shirts to the general public and we have no consumer-facing retail store in Silao. We work exclusively on corporate purchase orders with CFDI 4.0 invoicing and, when applicable, pedimento documentation.
