Harmonized System is recorded in this encyclopedia from the source named below.
Overview
The Harmonized Commodity Description and Coding System, also known as the Harmonized System (HS) of tariff nomenclature is an internationally standardized system of names and numbers to classify traded products. It came into effect in 1988 and has since been developed and maintained by the World Customs Organization (WCO) (formerly the Customs Co-operation Council), an independent intergovernmental organization based in Brussels, Belgium. It is used by over 200 WCO member countries and economies as a basis for their Customs tariffs and for the collection of international trade statistics as well as many other purposes.
