Passport is a carrier that specializes in international shipping for e-commerce companies.
When a client chooses to use Passport Shipping for their international OWD orders, OWD will pick and pack the order as normal. The package then gets sent to a Passport Shipping facility to complete the shipment to your customer.
Shipping times could be slightly longer when using Passport, however, it can often be a cheaper option when it comes to postage rates.
