What is the Harmonization System?
Harmonization (HTS Code) is the method used by international customs agencies for understanding what material is being shipped into their countries. If you ship products internationally you will need to provide the carrier such as UPS, FedEx, or DHL a 10 digit harmonization code that will describe what kind of product you are shipping. The carrier will then provide this code to customs when they bring the item across the border.
The Wikipedia entry for the harmonization system give more detailed information including link to resources where you may look up an appropriate Harmonization code for your product.
Uploading the HTScode in batch
Shipedge cannot provide you with the harmonization code, nor do we keep a list of available codes. We do provide a space for you to enter the code so that it gets sent along to the carrier when you ship internationally. This code is attached to the SKU information. It can be uploaded with the SKU information by putting it into the HTScode field in the csv file MASTE-Import_Inventory_Description.csv. For more information on uploading SKU information from a CSV see How To Upload Inventory From A Spreadsheet Or CSV.
Here is the MASTE-Import_Inventory_Description.csv. The Harmonization HTScode may be uploaded when the inventory is uploaded.
Manually adding the Harmonization code to an existing SKU
If an existing SKU does not already have the Harmonization code you will need to add it when the product is in the processed state before you print labels. Edit the address (see the screen shots below) and then follow the link that allows you to edit the SKU.
