A tariff code, sometimes referred to as a commodity code or HTS Code, is a code published by each individual country or group of countries. It is comprised of the 6-digit HS code and may have an extension to the code comprising of usually between an additional 2 to 6 digits, depending on the country.
The additional digits permit each country to set duty rates and taxes for a greater range of products, monitor controlled goods and collect import statistics. Tariff codes are required for import.
