UNAIDS manages its supplier and potential supplier base to ensure reaching out the market appropriately when conducting competitive processes for its procurement.

UNAIDS HQ, liaison, regional and country offices should maintain a roster of potential suppliers to facilitate tendering document distribution, but the existence of such a roster does not eliminate the need for open competition—that is the basis for all formal procurement in UNAIDS.

Staff conducting procurement is responsible for verifying and updating supplier information in every new contract. This includes updating banking information, verifying the eligibility of the vendor to receive a contract and identifying suppliers who are declared ineligible to conduct business with UNAIDS.

UNAIDS encourages participation in country UN teams efforts to establish a common UN Roster of potential suppliers and to share any internal roster with other relevant UN agencies.
