Laredo, El Paso, and Brownsville handle the highest U.S.-Mexico trade volumes. Texas-headquartered companies operating Mexican maquilas face daily compliance work across CBP (U.S.) and SAT/Aduanas (Mexico). USMCA + IMMEX layering plus operational broker coordination defines the work.
This guide covers Texas-Mexico Trade Flow. For SMB importers and exporters, the practical implementation depends on volume, sector, and operational structure.
For background, see /usmca-cusma/ and our complete cross-border practice.
Laredo cross-border (Texas-Tamaulipas)
#1 U.S. land port. ~$354B annual trade. Auto, electronics, machinery dominate. Most active cross-border ops.
El Paso (Texas-Chihuahua)
Second-busiest. Auto, electronics, medical devices. Connection to Juárez maquila cluster.
Brownsville (Texas-Tamaulipas south)
Auto, agriculture, oil/gas. Smaller volumes than Laredo/El Paso.
Operational coordination
Mexican broker prepares pedimento; U.S. broker prepares 7501. Synchronization required for clean passage.
