There is not currently a package type called Tube available in ShipStation, so Stamps.com recommends using the package type Non-Rectangular Package for these shipments and entering the appropriate tube dimensions to ensure you receive the proper rate for the label.
This is true whether you are using your own custom packaging or the USPS-provided Dual-Use Priority and Priority Mail Express tubes.
The table below provides USPS First Class and Priority services details when shipping with tubes. For each service, the same weight and size restrictions that apply to packages also apply to tubes.
Shipping Option |
Details |
---|---|
USPS First Class Mail |
The package's weight determines the rate. Height and width dimensions will be the same.
|
USPS Priority Mail |
Priority Mail uses zone-based pricing. That means for certain zip codes you will have to enter the dimensions of your tube to obtain the correct rate. Incorrect dimensions can result in returned parcels or rate adjustments applied to your postage provider account after shipping.
Review the USPS guide to help determine the girth of your package. |
USPS Dual-Use Tubes |
If you ship using the small or medium Priority Mail or Express tubes provided by the post office, you will still select package type Non-Rectangular Package and enter the dimensions for the tubes into ShipStation. |
