What is an HTS Code?

The Harmonized Tariff Schedule (HTS) is a standardized numerical method of classifying traded products. It is used by customs authorities around the world to identify products when assessing duties and taxes and for gathering statistics.

How to Calculate Import Duty

Import duties are calculated based on the HTS code of your product and the country of origin. Different products have different duty rates, and trade agreements between countries can affect these rates. TariffMath calculates the exact duty rate you'll pay, including any additional tariffs or special programs that may apply to your specific product and country combination.
