About

The HS Tracker is a toolset that has been developed by the Secretariat of the World Trade Organization (WTO), [with the support of the World Customs Organization (WCO),] to allow different stakeholders (e.g. customs and trade officials, statisticians, lawyers, researchers, etc.) to track the changes of particular headings or subheadings across different versions of Harmonized Commodity Description and Coding System (HS).

The HS is a multipurpose international product nomenclature developed and maintained by the World Customs Organization (WCO). It is periodically updated to secure uniform interpretation or to reflect changes in trade patterns, changes in manufacturing processes or technological advancement; it also addresses environmental and social concerns (e.g. FAO, CITES, Montreal protocol, etc.).

The World Customs Organization aims at enhancing the effectiveness and efficiency of Customs administration through the uniformization and harmonization of customs legislations. To assist the Members, the WCO has developed rules, standards and international norms such as the HS nomenclature over the past 60 years. To this day, the WCO continuously provides documentation such as the Correlation Tables that are key elements to the smooth understanding and interpretation of the different Harmonized System editions (1992, 1996, 2002, 2007 etc.).

The Subheading visualizer function displays graphically the manner in which a specific HS code has changed across different versions of the Harmonized System (e.g. mergers, splits and complex cases), including the explanation by the WCO on why the changes were undertaken in the context of a particular amendment. The English and French versions of these explanations, as well as the correlation tables, have been sourced directly from the WCO webpage. However, the information in Spanish is an unofficial translation by the WTO Secretariat.

The HS at a glance function provides a broad overview of the HS amendments by consolidating the different versions of the HS in one combined structure that was developed by the WTO Secretariat based on the information by the WCO and adjusted according to the different transposition exercises of the WTO Schedules of concessions. The filters and search functions make it possible to browse multiple HS nomenclatures simultaneously for a particular set of codes, and determine whether they were affected by a particular amendment to the HS.
