Why Cross-Border Logistics
Why the border is your advantage
Inventory waits in Mexico and crosses into the US every business day. You keep Mexico's cost base and gain the delivery speed of a US fulfillment center.
Mexico costs, US speed
Products sit in our IMMEX-certified warehouses in Tijuana and cross into San Diego daily, so you get Mexico-based cost advantages with the delivery speed of a US fulfillment center.
Duties only on what crosses
Without IMMEX you owe duties on all inventory when it enters the US. With it, stock waits duty-free in a bonded warehouse and duties are paid only on the orders that cross each day.
Clearance without the wait
Licensed customs brokers process thousands of entries per month at the Otay Mesa and San Ysidro crossings, and most shipments clear within the same business day.
