What Is a “Border Box” (or cross-border shipping service)?

This is a great option for the following scenarios:

1. Booking shipments from 80-250 lbs  for BOTH DOMESTIC AND INTERNATIONAL.
2. Existing customers may want to use the Border Box as a supplemental air shipment while they are waiting on their sea shipment.
3. Use it to ship items left behind at origin;  this is probably the lowest cost option in the market to take care of small problems.
