UNSPSC

The United Nations Standard Products and Services Code (UNSPSC) is a taxonomy of products and services for use in eCommerce. It is a four-level hierarchy coded as an eight-digit number, with an optional fifth level adding two more digits.

Version 16, released in 2014, contained over 50,000 commodities. The latest release of the code set is 19.0501 (as of July 2016^[update]).

The UNSPSC competes with a number of other product and commodity coding schemes, including the European Union's Common Procurement Vocabulary, Germany's Eclass, and GS1's Global Product Classification.

The UNSPSC was created upon the signature of a Memorandum of Understanding signed on September 29, 1998 by John S. Svendsen, the director of the Inter-agency Procurement Services Office (IAPSO) of the United Nations Development Programme (UNDP) and on November 1, 1998 by Lawrence M. Barth, a Vice President of the Dun & Bradstreet Corporation. The development of the first version was overseen by Peter R. Benson, who was also responsible for the design and development of the code management procedure as a modification of the Delphi statistical forecasting method. The process allowed for the rapid development of consensus without dominance or influence.

The ECCMA, a non-profit membership association, was formed in 1999 to manage and promote the UNSPSC until March 2003, with the release of version 6.0315. The UNDP then appointed GS1 US as code manager in May 2003 and ECCMA develops the ECCMA Open Technical Dictionary (eOTD) and the international standards ISO 22745 and ISO 8000.

The four primary levels of the code are: Segment, Family, Class and Commodity.

Each level is coded in two decimal digits, with '00' treated specially to give segments, families and classes their own eight-digit codes.

Thus 'Cats' are coded as 10101501, 'Dogs' are coded as 10101502 and 'Cattle' as 10101516. The class of 'Livestock' is 10101500; the family of 'Live animals' is 10100000, and all in the segment 10000000 of 'Live Plant and Animal Material and Accessories and Supplies'.
