Worth knowing in San Antonio
The metro's truck assembly plant draws a cluster of suppliers around the south side, many on tight, sequenced deliveries. They need returnable or expendable packaging that matches their customer's specifications. San Antonio is also a trade route to Mexico through Laredo, and some distributors here repack cross-border freight; those buyers ask for heavy domestic cartons that survive long truck hauls.
Interstate 35 runs south to Laredo, the busiest US land port for trade with Mexico, so many cross-border shippers stage freight here.
