## What is a Harmonized Tariff code?

A Harmonized Tariff code (HTS code) is a standardized numerical method of classifying traded products. This international system, used by customs authorities worldwide, provides a uniform classification structure for identifying products, determining import duties, and collecting trade statistics.
