How to Use Tariff Numbers and Harmonized Codes in Shippo

The tariff number of an item, also known as the "harmonized code" or "HS code," is a standardized number given to a particular product or type of product for easier identification during customs processing and better standardization of international shipping.

These product-specific codes are documented in the Harmonized System (HS) maintained by the World Customs Organization (WCO).



Are tariff numbers required?

Tariff numbers are not required for international shipping. Not including a tariff number should not negatively impact your package's shipping progress.


Why should I consider using a tariff number?

Tariff numbers exist for almost every product involved in global commerce and ensure uniformity of product classifications worldwide. In some cases, using a tariff number or harmonized code can help smooth the customs process and avoid misclassification of items and applicable fees. 


What does a tariff number look like? 

A complete tariff code is no less than six digits and can be up to ten. The more digits in a tariff code string, the more specific the product it identifies. A string of fewer than six digits is considered a partial tariff number and represents a broad product category or chapter of products in the HS rather than a single item.


Where can I find a list of tariff numbers?

Can I import tariff numbers from my store or set default tariff numbers? 

There is no way to import or add default customs items/tariff numbers in Shippo, so if you do use them, you will have to add them manually during this customs step of the label creation process. 


How can I add a tariff number for an item in Shippo?

You can add a tariff number to a customs item when entering your Customs Declaration in Shippo. Either add a new customs item or click Edit next to an existing customs item, to add this information.
