Mexico Export Surge Strained by Driver Shortages, Border Rules

4% year-over-year in June and marking five consecutive months of double-digit expansion—driven primarily by surging technology and electronics shipments. However, this growth is colliding with a structural capacity crisis: stricter B-1 visa enforcement, English-language requirements, and intensified cargo documentation scrutiny are shrinking the pool of qualified cross-border drivers. Simultaneously, automotive production—traditionally the backbone of US-Mexico freight—is softening due to tariff uncertainty and production shifting, while infrastructure bottlenecks at Manzanillo port are further complicating the picture. For supply chain professionals, this dynamic creates a paradoxical environment: strong demand meets constrained supply.

The load-to-truck ratio remains favorable for carriers in key corridors, supporting sustained rate firmness despite August softening at Laredo. The 81% modal concentration of Mexico's land freight in trucking means capacity constraints ripple across the entire cross-border supply chain. Shippers are being forced to prioritize compliance-friendly carriers over pure cost optimization, fundamentally reshaping procurement strategies. Looking forward, the trajectory hinges on three variables: tariff policy uncertainty, immigration enforcement implementation, and infrastructure capacity investments.

Intermediate goods imports are at 80% of total Mexican imports, signaling export momentum could persist through year-end—but only if capacity constraints don't throttle throughput. Organizations should stress-test their Mexico exposure and consider geographic diversification or nearshoring strategies to de-risk this increasingly volatile corridor.
