The Central Product Classification (CPC) is developed and maintained by the United Nations Statistics Division (UNSD). It constitutes a complete product classification covering all goods and services. It serves as an international standard for assembling and tabulating all kinds of data requiring product detail, including statistics on industrial production, domestic and foreign commodity trade, international trade in services, balance of payments, consumption and price statistics and other data used within the national accounts. It provides a framework for international comparison and promotes harmonization of various types of statistics related to goods and services.

The first version of the CPC, the Provisional Central Product Classification, was published in 1991. Version 2.1 was published in 2015.
The primary purpose of CPC Version 2.1 is to classify the goods and services that are the result of production in any economy.
