UNSPSC is an open classification system for products and services. UNSPSC codes are 8 numeric digits that correspond to a commodity such as Pencils or Air Filters. The UNSPSC classification system is organized as a 4 level hierarchy of: Segment, Family, Class, and Commodity. Each level of the hierarchy represents 2 digits in the UNSPSC code. Products should be classified at the commodity level whenever possible. Buying organizations use UNSPSC codes to generate reports of spend by category. Some buying organizations may require this field to be present.
