If you would like to submit weights for products to be used for shipping calculations you can use the Import Package Weights under the Catalog tab. You will need to use the PSS SKU format and include ShippingWeight.weight_major (Pounds) and ShippingWeight.weight_minor (Ounces). Both fields must be used if a SKU is present, a value of 0 is valid. Please remove any template notes prior to uploading into PSS. Once you have completed the file save it to your computer as a .csv file and it can be uploaded back into PSS. The Export Package Weight will give you a receipt of everything that has been imported into PSS.
