Documents for Mexico–USA Shipping: What Shippers Must Prepare

A commercial invoice with seller, buyer, Incoterm if you use one, detailed description, quantities, values, and currency. A packing list that matches piece count, weights, and marks on the pallets. Vague lines such as “parts” or “supplies” are how secondary inspection begins. If you have multiple POs, list them cleanly instead of hoping the officer will sort your ERP.

For USMCA claims, origin documentation belongs in the file when you are actually claiming preference—not as a decoration on a shipment that does not qualify. Your customs team owns that call.

In Mexico, a patente-holding agente aduanal files the pedimento. In the United States, a licensed customs broker handles entry or export filing as required. COL books the truck, coordinates bilingual updates, and aligns pickup times with a file that those professionals say is ready. We will not “just send it” against their advice.

IMMEX, in-bond, and temporary imports are program structures your Mexican legal and customs teams maintain. We move trailers that fit the structure you already have—at Laredo, Colombia Solidarity, Otay Mesa, or El Paso/Juárez—not a structure we invent on the phone.

Dangerous goods need SDS, UN data, and emergency contacts in addition to the commercial stack. Food and certain animal or plant products can trigger USDA, FDA, or Mexican counterparts. Tell us before dispatch. Extra certificates are not a same-morning surprise if you want a typical range instead of a detention story.
