Saltillo and Ramos Arizpe are one of Mexico's densest automotive clusters, with GM and Stellantis assembly plants and the suppliers that feed them. Pick an origin or destination in the directory to open its lane guide, and read how the Laredo handoff and Mexican paperwork work on Saltillo freight. Cargado is a marketplace where brokers post Mexico and Canada truck freight and vetted carriers bid on it.

Saltillo, the Coahuila capital, and Ramos Arizpe next door are automotive country. GM's Ramos Arizpe complex built more than 350,000 vehicles in 2024, including the Equinox and Blazer EVs (GM Authority), and Stellantis runs engine, stamping, truck and van plants in the area that build Ram trucks and ProMaster vans (Tetakawi). Around them sit the tier suppliers that feed the plants. Northbound, expect finished vehicles on specialized carriers and automotive parts, stampings, engines and appliances in dry vans; southbound, steel, resins, components and packaging for the plants, plus food and beverage for the region. Monterrey is just east, and Laredo is the gateway for most cross-border loads.
U.S. guides run from Saltillo to Laredo, Dallas, Fort Worth, Houston and the Midwest, Southeast, Northeast and West Coast, and back from the same regions plus McAllen and Milwaukee. Mexico guides connect Saltillo with Monterrey, Nuevo Laredo, San Luis Potosí, Querétaro, the Bajío, Toluca, Mexico City, Puebla, Guadalajara, Hermosillo and Tijuana, and inbound also with Chihuahua, Ciudad Juárez, Mexicali, León and Cuernavaca. Canada guides reach Toronto, London and Vancouver. For each lane, confirm whether you need the Mexico leg, the U.S. leg or the door-to-door move, and, for international lanes, who covers the border transfer; domestic Mexico lanes have no crossing.
Most Saltillo freight for the U.S. or Canada crosses at Laredo. A Mexican linehaul carrier runs the trailer to a Nuevo Laredo yard, a transfer carrier crosses the World Trade Bridge, and a U.S. carrier picks up in Laredo; a transload moves the cargo to another trailer at a dock instead. Post the leg you need covered, and check what each bid includes: the transfer, any transload, trailer use and detention.
Plant deliveries run on appointment windows, returnable racks and dunnage, and many suppliers ship just-in-time. Put the dock hours, the appointment, the rack or pallet count and any returnable equipment on the posting so the carrier prices the real move. Finished vehicles need auto-hauler carriers, a separate market from dry van carriers.
Any leg inside Mexico needs a carrier with Mexican operating authority, and for every Mexican leg confirm who issues the CFDI, Mexico's electronic tax document, with Carta Porte details when required. Northbound, a U.S. customs broker usually files the U.S. entry; southbound, the importer's licensed Mexican customs broker, or an authorized representative, files the Mexican entry. Agree on free time, detention and storage before dispatch.
Most Saltillo lanes into the U.S. and Canada cross at Laredo, about three and a half hours northeast, where the World Trade Bridge is the commercial default. Each cross-border lane guide on this hub names the crossing it uses; the domestic lanes to Monterrey, Mexico City or the Bajío have no crossing.
Yes, for any leg inside Mexico: it needs a carrier with Mexican operating authority. A lane to a U.S. city usually runs Saltillo to a Nuevo Laredo yard on a Mexican carrier, then a transfer across the bridge and a carrier with U.S. authority to destination. For a Canadian destination, also confirm U.S. transit paperwork, Canadian entry and each carrier's authority. State the leg you need covered when you post on Cargado.
Post the pickup and delivery, the date, the equipment and the leg you need covered. For a Mexico move, include the crossing and the handoff plan; for a Canada lane, the customs broker and the release arrangement. Vetted carriers that run the corridor bid, and you compare what each bid covers before you book. Where a corridor has enough bid history, Cargado Market Rates gives you a reference built from carrier bids before you quote.
Dry van leads, carrying automotive parts and appliances. Open deck carries stampings, coils and machinery, and reefer demand comes from food and beverage. Post the trailer type with the weight, dimensions and loading requirements so carriers can price the load.
