The Central Product Classification (CPC) is a standard classification of products and services, with for each of them an indication of the economic activities or government functions producing or providing them.

The Central Product Classification (CPC) constitutes a complete product classification covering goods and services. It serves as an international standard for assembling and tabulating all kinds of data requiring product detail, including industrial production, national accounts, service industries, domestic and foreign commodity trade, international trade in services, balance of payments, consumption and price statistics.

Statistics based on CPC Version 2.1 are useful in studying transactions in goods and services in detail and as a basis for developing lists of goods and services for specific purposes, such as price statistics surveys. It has broad acceptance as an international standard and facilitates the maintenance of constant categories of products.

The CPC was originally provided as a pdf document (in English) here: Central Product Classification (CPC) Version 2.1 (it is not available in print, nor are translations provided1).

With the support of Wikinetix a #pdf2wiki conversion was performed during the winter of 2019.

These usability improvements were added to #CPC hashtags:

  • in order to support multi-lingual debate via social media and the easy retrieval of various contributions regarding a product or service #tagcoding hashtags were added for all sections, divisions, groups and classes, and for some sub-classes.
  • all references to ISIC v4 classes were replaced with direct links to the class' wiki pages
  • the ISIC class pages (and some other pages) got tagged with #cpc-codes and terms from the CPC classification such that the alphabetic #tagcoding tags for products, services and bads (a Hashtag cloud) supports the discovery of #cpc-codes and the ISIC class that produces the service or product.

The English wiki version of the classification with #tagcoding hashtags can be accessed here: #CPC hashtags.

A translation into other languages is most desirable, for instances as part of a #digicoop1b - Platform for sharing digital public goods.

Depending on whether language or local government unit is the leading determinant for the provisioning (gaps) of a product or service, a #cpc hashtag can be combined with either:
