San Antonio is the first big market north of Laredo on I-35, a Toyota plant town and the staging point for Texas freight headed into Mexico. Pick a lane in the directory to open its guide, and read how the Laredo handoff and Canada customs work on San Antonio freight. Cargado is a marketplace where brokers post Mexico and Canada truck freight and vetted carriers bid on it.

San Antonio builds trucks and stages freight between Laredo and the rest of the U.S. Toyota is investing $3.6 billion to expand its San Antonio plant, adding 2.5 million square feet and 2,000 jobs to build the Tacoma alongside the Tundra and Sequoia by 2030 (Automotive Logistics, July 2026), and its supplier park ships parts in both directions on I-35. The city's warehouses stage southbound consumer goods, food and components for Mexico and receive northbound automotive parts, appliances and machinery that cleared at Laredo. I-10 and I-37 connect San Antonio to Houston, the Gulf and the Southeast, and I-35 runs north to Austin, Dallas and the Midwest.
This hub carries seven guides. Mexico guides run San Antonio to Monterrey and Torreón to San Antonio; each lane guide names its crossing, and you confirm it with the carrier. U.S. guides run into San Antonio from Laredo and McAllen, lanes that may connect with a Mexico shipment or may be domestic. Canada guides run San Antonio to Winnipeg and into San Antonio from Calgary and Toronto. For each lane, confirm whether you need the U.S. leg only, the move into Mexico, or the customs handoff with Canada, and post the pickup and delivery for the leg you are buying.
For a full move into or out of Mexico, post the Mexican origin or destination so carriers see the whole shipment. For a separately booked U.S. leg, post the actual pickup yard and the receiving facility, and describe the connected shipment, its customs status and any handoff. Compare bids that cover the same scope of work.
For freight connected with Mexico, use the lane guide's named crossing as the starting point and confirm it with the carrier and customs broker. If carriers change at the border, identify the yards, the transfer provider and whether the cargo stays in its trailer or is transloaded at a dock. Confirm the operating authority of the carrier on each leg, and check what each bid includes: the transfer, any transload, trailer use and detention.
The carrier files an ACI eManifest northbound or an ACE eManifest southbound before arrival, and the importer or its customs broker arranges release, with a PARS or PAPS reference when one is used. Provide the invoice information the importing country requires and any USMCA certification of origin needed to claim preferential treatment, and put the broker and release arrangement on the posting. Cross-border authority does not by itself allow domestic hauling in the other country, so confirm operating authority, driver eligibility and cabotage restrictions before adding a domestic leg.
Laredo to San Antonio is a U.S. lane that may connect with a Mexico shipment. Confirm where the cargo starts or ends, its customs status and whether your booking includes a border transfer. If you need the full move, post the Mexican origin or destination; if you need only this leg, post the actual Laredo yard and the San Antonio facility and describe the connected shipment.
A carrier with Canadian operating authority, an ACI eManifest filed before arrival, and release arrangements with the importer or its customs broker, including the PARS reference when one is used. Provide the invoice information Canadian entry requires and any USMCA certification of origin needed to claim preferential treatment. Check cabotage eligibility before adding a domestic Canadian leg.
Post the pickup and delivery, the date, the equipment and the leg you need covered. 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, consumer goods and food. Open deck carries machinery and building materials, and reefer carries produce and beverages. Post the trailer type with the weight, dimensions and loading requirements so carriers can price the load.
