27.10. The final draft of CPC, called the provisional Central Product Classification, was approved by the Statistical Commission and recommended for use by member States at its twenty-fifth session in February 1989. The Provisional Central Product Classification was published in 1991. Since then, there have been several revisions of CPC and in 2008 CPC, Version 2.0, was completed. The Statistical Commission had adopted its structure at its thirty-seventh session in March 2006. This version of CPC is divided into 10 sections, 71 divisions, 324 groups, 1,267 classes and 2,738 subclasses. Sections 0 to 4 are based on HS07, and aggregate the HS codes into product categories suitable for various types of economic analysis within the national accounts framework. Sections 0-4 of the Classification, like SITC, provides for the rearrangement of HS-based international merchandise trade statistics for analytical purposes. Sections 5 to 9 of CPC, Version 2.0, go beyond the HS categories to provide a classification of service products.
27.12. International practices in the use of CPC. The analytical value of CPC is being recognized more and more by international organizations. For example, the statistical Classification of Products by Activity (CPA) was created at the level of the European Union (EU) by assigning CPC products to one single activity category. CPA is a product classification whose elements are related to activities as defined by NACE, Rev. 2. Each product - be it a transportable or non-transportable good or a service - is assigned to one single NACE, Rev. 2, activity. The linkage to activities as defined by NACE, Rev. 2, gives the CPA a structure parallel to that of NACE Rev. 2 at all levels distinguished by NACE Rev. 2. However, the detailed linkage between products and activities could be established only to a certain degree. There are nevertheless cases where products can be assigned to activities only at a higher level than the class level or even where a class in CPA 2008 has no activity counterpart in NACE Rev. 2,.
