Harmonized Commodity Description and Coding System (HS).

How to determine the tariff fraction of my product?

In the 1980s there were more than 15 different ways of coding a good in the world, based on the different classification systems that existed, which meant an important barrier in international trade, for these reasons and under the tutelage of the World Customs Organization (WCO), a Committee was established within the Brussels Customs Cooperation Council with the aim of developing a new international nomenclature and resulting in the International Convention on the Harmonized System of Commodity Designation and Coding.

The products listed in the databases are identified by the "Harmonized System" (AS) internationally accepted by the World Customs Organization.

The broadest product categories chapters are identified by 2 digits, they in turn are subdivided into 4 digits or heading, 6-digit or subheading level and 8-digit or tariff line level, the more digits the code contains, the more detailed the code will be the categories.


The nomenclature of the Harmonized Commodity Description and Coding System is the most widely used as a benchmark for coding in foreign trade around the world and also serves to facilitate international trade, to homogenize statistics on trade, facilitate trade negotiations, lower costs and enable the use of computer tools.

The SA is used by more than 200 countries and Customs Unions, representing more than 98% of international transactions.  It is reviewed every five years (except in cases of urgency), to include new items derived from technical or commercial progress and to eliminate (integrating products into more generic headings) those products that fall into disuse.

It is always recommended to have the advice of a customs broker since they are the experts in the subject and will help you to perform the correct coding of your merchandise and speed up the process.
