UNSPSCs Look-Up Tool for Buyers and Vendors

OSD uses United Nations Standard Products and Services Codes (UNSPSCs) to classify goods and services in COMMBUYS. Buyers use these codes when preparing bids and vendors select UNSPSCs to receive notifications of bidding opportunities that align with their businesses.

OSD has developed an easy-to-use tool to assist both buyers and vendors in identifying UNSPSC information associated with commodities and services.
