The Harmonized Commodity Description and Coding System, generally referred to as the ’Harmonized System’, or simply ’HS’, is a multipurpose international product nomenclature developed by the World Customs Organization (WCO). It comprises about 5,000 commodity groups each identified by a six—digit code. The system is used as a basis for customs tariffs and for the collection of international trade statistics. Over 98% of the merchandise in international trade is classified in terms of the HS. These codes are also known as ’H.S. Codes’, ’Tariff Codes’ or ’Commodity Codes’.
