There are many reasons for mapping to other codes and classifications:
Off-the-shelf ProClass mappings to UNSPSC (United Nations Standard Products and Services Code) and CPV (Common Procurement Vocabulary) are available to purchase. Please note that the mappings are best fit (1-to-1, i.e. each ProClass code is mapped to the single most appropriate UNSPSC / CPV code.). For full mappings please contact us for a quote.
The latest mappings are to version C17.1 of ProClass. These will be updated to C21.1 shortly after the release of this version of ProClass.
