International Standard Industrial Classification of All Economic Activities

"The International Standard Industrial Classification of All Economic Activities (ISIC) is the international reference classification of productive activities. Its main purpose is to provide a set of activity categories that can be utilized for the collection and reporting of statistics according to such activities. Since the adoption of the original version of ISIC in 1948, the majority of countries around the world have used ISIC as their national activity classification or have developed national classifications derived from ISIC.

Standard International Trade Classification

"The scope of SITC, Revision 4, remains the same as that of SITC, Revision 3, that is to say SITC, Revision 4, covers all goods classifiable in HS except for monetary gold, gold coin and current coin. All SITC, Revision 4, basic headings (except for 911.0 and 931.0) are defined in terms of HS07 subheadings. Since SITC is now recommended only for analytical purposes, there was no need - except in several special cases - to create new basic headings in SITC, Revision 4, that would be in one-to-one correspondence with the new HS07 subheadings.

Classification of the Purposes of Non-Profit Institutions Serving Households

"In principle, COPNI classifies individual outlays of NPISHs according to the purpose they serve. In most countries, however, there is little information about the activities of NPISHs and so, for practical reasons, the NPISHs themselves will usually constitute the units of classification. Many, perhaps most, NPISHs have a single purpose and can be unambiguously allocated to one of the purposes listed in the classification.

Central Product Classification

"The name 'Central Product Classification' is intended to indicate that the purpose of CPC is to provide a framework for international comparison of various kinds of statistics dealing with goods, services and assets. Basically, CPC is intended to be used for different types of statistics, for example, industrial statistics and national accounts, price statistics, foreign trade statistics (including trade in services) and balance-of-payments statistics."
