U.S.–Mexico cross‑border freight is the movement of commercial goods between the United States and Mexico through a coordinated process of export preparation, customs clearance, border transfer and inland delivery. It requires accurate documentation, compliance with both countries’ customs rules and authorized carriers to ensure freight moves efficiently from pickup to final delivery. 

Below is a practical overview of how cross‑border freight typically moves — northbound and southbound — and what to expect at each stage. 

How Does Cross‑Border Freight Shipping Work? 

Cross‑border freight moves through a defined lifecycle that includes: 

• Origin pickup
