Harmonized Codes are internationally recognized codes to classify an item for tax purposes. Harmonized Codes (also referred to as Tariff Codes, TARIC, Customs Tariffs, Harmonized Tariff Codes, and Harmonized System Codes) expedite the shipping process for international orders. Once an order reaches an international border, a country's customs office uses these codes to identify and to assess taxes, duties, and fees for what you are shipping.
Most destination countries use the Harmonized Code system while a few countries require the description instead. It is best practice to include both the Harmonized Code and a detailed description when shipping internationally. While it is not required, using Harmonized Codes for your international shipments will:
Help your packages move through customs more quickly
Help to ensure correct taxation on your exported products
Help to minimize the chances of loss of your products
