Alphabetical Index
(to the HS 2017)

Because the classification of an article depends on many legal and technological factors, the Alphabetical Index should not be regarded as a substitute for the basic texts, i.e., the Harmonized System and its Explanatory Notes.

HS Classification Handbook
(second edition)

This handbook provides a detailed description of the Harmonized Commodity Description and Coding System, precise arrangements for its maintenance and describes the complementary publications of the Harmonized System.
This document is available in English and French.

Classification Decisions

The Classification Decisions taken by the Harmonized System Committee summarizes all the decisions that have been taken during the 27th to 46th Sessions (2001-2010).
This document is available in English and French.

What can be found here ?

The Harmonized System database contains the HS Nomenclature (2007, 2012 and 2017 versions), the HS Explanatory Notes (4th edition - 2007, 5th edition - 2012 and 6th edition - 2017), the Classification Opinions, the Alphabetical Index, the Classification Decisions, the Amendments to the HS implemented as on 1st January 2017 and the correlation tables between the 2012 and 2017 HS versions.

You can do “multi-criteria” searches by keyword or HS codes, print your research, create personal notes and cross navigation between Explanatory Notes, Classification Opinions and Alphabetical Index.

The online database is updated twice a year following the Harmonized System Committee decisions.
