USPS cubic pricing is available by default when creating labels in ShipStation.
Cubic rates are ideal for small, heavy packages since the pricing is based on the volume of the package instead of the weight.
Eligibility:
-
Packages using domestic Priority must measures 0.50 cubic feet or less and weigh 20 pounds or less
-
Packages using Ground Advantage must measures 1.00 cubic feet or less and weigh 20 pounds or less
To receive cubic rates in ShipStation:
-
Choose USPS Ground Advantage (formerly Parcel Select Ground) or a domestic Priority service.
-
Choose a package type of Package.
-
Enter the package weight & dimensions.
ShipStation will automatically apply the cubic rate whenever it's cheaper than the priority rate.
USPS offers a special cubic rate option for a package type called Soft Pack or Polybag. These package types are not yet available in ShipStation, but we plan to make them available in the future.
If you wish to ship using ShipStation Soft Packs, please contact ShipStation support to enable this feature for you.
Both domestic Priority and Ground Advantage require the following to be able to ship using Soft Pack cubic pricing:
-
The mail piece must be 20 lbs or less.
-
The longest dimension cannot exceed 18 inches.
-
May not be in rolls or tubes.
