So you're shipping an international order, and you see the field Harmonization Code on the Customs Declarations section of the Order Detail popup. What is it for?
The purpose of a Harmonization Code (also referred to as Tariff Code, Customs Tariffs, Harmonized Tariff Codes, and Harmonized System Code) is to expedite the shipping process for international orders. This universal economic language and code system for trade covers most internationally sent goods and merchandise.
Once an order reaches an international border, a country's customs office uses these codes to identify and to assess tax for what you are shipping. We recommend that you properly identify, establish, and list your harmonization codes well before you create labels.
Adding Harmonization Codes to Orders
ShipStation offers three ways to add the harmonization code to your international orders:
1. Manually: Open the Order Detail window, or use the sidebar, and manually add or remove harmonization codes to your international orders.
2. Pre-defined customs values: Set your International Settings to use pre-defined customs values, and designate which harmonization code will appear for all international orders.
3. Product defaults: Configure your international settings set to create customs declarations based on order items, then you can store harmonization code just like any other product default. The harmonization codes can also be set as product defaults in bulk. See this article for information on importing products via CSV files.
