Global Advantage Program

Explanation of Global Advantage Program (GAP), which applies to international shipments using First Class or Priority services.

The Global Advantage Program (GAP) is an international shipping program through that provides an economical way to ship merchandise internationally.

ShipStation users have access to two types of GAP services:

  • Global Advantage Program Single Label

  • SmartSaver

Global Advantage Program - Single Label

When printing single USPS international labels for First Class or Priority services with your One Balance account, ShipStation automatically prints a GAP label.

GAP benefits include:

  • Up to 65% in savings over the retail USPS Package shipping cost

  • No need to print Customs Declaration forms

  • No need to change your workflow in ShipStation

How it Works

Similar to many international consolidators, you first send your packages via USPS to a domestic sorting facility. There, your international shipments are relabeled for their destination, receive their appropriate customs forms, and are then sent on to their final destination.

This means the label you print will be a domestic label addressed to the Postal Processing facility instead of the final destination.

If you have a One Balance account, you are automatically enrolled in the Global Advantage Program.

GlobalPost SmartSaver

For businesses that ship 10 or more international shipments per day, GlobalPost SmartSaver offers an additional 15% in savings on GAP labels!

With the SmartSaver service, you consolidate all your individual international parcels into a single, large container. You then send the large container to the sorting facility where the individual shipments will be sorted and sent on to their final destination.

By printing a GAP SmartSaver label with a scan code, the tracking for all included shipments will update when the large package gets scanned.

See the Global Advantage Program section in our article for instructions on how to print labels for a consolidated shipment.

Contact GlobalPost to apply for the SmartSaver service.

DDP from US to Canada

If you ship from the US to Canada using First Class Mail International, you will have the option to make it a Delivery Duties Paid, or DDP, shipment. When you select this option, you will be charged a flat fee that will pay duties or taxes in advance, rather than your recipient paying them upon delivery.

In ShipStation, there is a Duties/Taxes drop-down menu on the Configure Shipment Widget that will appear on any shipment with a destination in Canada. Select the option to PrePay Duties and Taxes if you wish to prepay this flat fee.


Learn more about this setting in our Bill International Duties to Payor help article.
