Codes and Guides

 
This section seeks to provide information to importers and exporters trading with both EU (European Union) and non-EU countries, and any other parties interested in international trade. EU trade data is collected through the Intrastat system. Non- EU data is collected from Customs entries, usually made through the Customs Handling of Import and Export Freight (CHIEF) system.
This site contains several country lists however two are of particular interest.
The first list is designed to help UK businesses find the correct country codes for their import or export declarations.

The second list helps people use the ‘build your own data tables’ database by identifying all countries and geographical areas since 1996.

The Harmonised System (HS) is a high-level international nomenclature owned by the World Customs Organisation (WCO), comprising of 6 digits and used by the majority of trading nations. These exact same 6 digits form the first part of the 8-digit CN code; however, often the EU requires greater detail than what's provided in the HS, either for statistical or tariff reasons. For these reasons many HS codes undergo a further 'split' into 8-digit CN codes.

In its role as producer of UK international trade statistics, HM Revenue & Customs (HMRC) produces data in accordance with two major classification systems: The Combined Nomenclature (CN) which is EU 'owned'; and, the Standard International Trade Classification, (SITC) which is owned by the United Nations Statistical Division.
