California-Mexico trade flows through Otay Mesa, Calexico, and Tecate crossings. Tijuana hosts a major maquila cluster (medical devices, electronics, aerospace). California-headquartered companies running Tijuana operations face similar dual-jurisdiction work as Texas-Mexico, with electronics and medical devices dominating the product mix.
This guide covers California-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.

Smaller volume. Tecate maquila cluster.
Tijuana medical device cluster
Major MedTech maquila ecosystem. USMCA qualification + IMMEX critical for U.S. customer compliance.
