Shipping Notes

How to ship with Consolidators

Consolidators will appear as carriers in the Carrier drop-down list in the Shipment Editor. Select the Consolidator and service, and process the shipment usually.


EasyPost only returns the manifest form for domestic shipments (DHL eCommerce). For international shipments, the DHL Global Mail International Manifest info is transmitted to DHL at the end of the day. Still, the manifest must be printed from your DHL Web Portal. You must give the driver the manifest forms for both if you are shipping domestic and international.


To use insurance with your EasyPost shipments, you can only select EasyPost Insurance in the Package or Shipment options. EasyPost Insurance outline:

  • Enter the value of the contents.
  • EasyPost charges 1% of the value with a $1 minimum.
  • EasyPost handles all claims, which are paid out within 30 days.
Insurance Settings

Apply to:

  • Divide Between Packages: The Base Amount you enter is divided equally among all packages in the shipment. The Base Amount will equal the Total Amount.
  • Process By Package: The insurance amount is applied on a package-by-package basis, and the Base Amount will be set up for individual packages on the Packaging tab under Package Options. StarShip may automatically calculate insurance based on the value of items packed into a box or packaging unit. StarShip only calculates the insurance when items are first packed; insurance will not be recalculated if items are moved or deleted from packaging. You can manually override any calculated values.
  • Each Package: The Base Amount is applied to the insurance amount for each package in the shipment. Therefore, the Total Amount will equal the Base Amount  multiplied by the number of packages in the shipment
