Harmonized Tariff Code
Import and Export Trade statistics are a rare example of real and genuine international co-operation. Virtually all the countries of the world use a common system of product classification, which is the six-digit Harmonised System (HS), agreed by the World Customs Organisation (WCO). The system starts at a 2 digit chapter breakdown consisting of 97 broad product sectors. Each of these sectors is further subdivided
into 4 and 6 digit classifications. The 6 digit Harmonised System covers over 6,000 product headings. Individual countries can add extra digits to provide greater product detail, up to a total of 10 digits. For example in the EU the eight digit Combined Nomenclature classification subdivides the 6 digit HS:
Beverages, spirits and vinegar 22 HS
Sprits and liqueurs 2208 HS
Spirits obtained by distilling grape wine and marc 220820 HS
Cognac 22082012 CN
Armagnac 22082014 CN
Grappa 22082026 CN
Brandy de Jerez 22082027 CN
