International Industry Classification Systems

Just as the US uses NAICS / SIC to organize their production statistics (and as Canada and Mexico also use NAICS; they are the other two NAFTA countries), some other countries and regions have their own industry classification systems. In addition, there are international classification codes used by countries belonging to the big NGO's such as the International Monetary Fund, the World Bank, and the United Nations.

International Trade Classification Systems

Where industry classification codes are used to track production, commodity classification codes are used to track trade between countries. Here are some of the more commonly seen codes:

HS Nomenclature 2007 and 2002 Editions (Harmonized System)
The Harmonized System was created and is maintained by the World Customs Organization. Developed in 1985, it has six-digit codes. Six digits are insufficient for many countries to describe their trade, but the HS provides a classification backbone which individual countries can extend to meet their needs. For example, the US has expanded the HS to ten-digits in its HTS.
NOTE: there is a newer HS edition, from 2012, but it requires a subscription.
SITC, Revision 4
Standard Industrial Trade Classification, from the United Nations. Created in 1950, it is a five-digit code with 10 major categories. It is used in such standard reference sources as Industrial Commodity Yearbook, etc. Click on the Language links for the full documents.
