About UNSPSC 51183511

UNSPSC 51183511 Phenformin, a Commodity code, covers pharmaceutical product procurement by state and local government entities through cooperative purchasing agreements and direct solicitations. State and local governments buy generic pharmaceutical products and over-the-counter medications under this code by establishing master supply contracts with manufacturers and distributors that serve multiple jurisdictions and healthcare facilities. Issuing bodies include state procurement offices administering multistate cooperative purchasing alliances, which centralize purchasing power across participating states and local government agencies. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, represents the primary recent issuing body; these cooperatives typically serve state agencies, counties, municipalities, and subordinate healthcare and correctional facilities that draw from established statewide or regional vendor panels.

MMCAP's recent RFP, posted January 20, 2026 with a response deadline of March 26, 2026, solicits manufacturers of generic multi-source pharmaceuticals and OTC products for a two-year contract term effective July 1, 2026, with optional extensions through June 30, 2028. The procurement requires vendors to supply products with specific National Drug Codes through three authorized wholesalers (AmerisourceBergen Drug Corporation/Cencora, Cardinal Health 110 and 112, and Morris & Dickson Co., LLC), certify cGMP and DSCSA compliance, maintain insurance including $5 million commercial general liability coverage, and accept pricing structures such as flat price, net price formats, or WAC-minus configurations. Evaluation emphasizes price competitiveness at 75 percent weight, with the remaining 25 percent split among fixed pricing, administrative fee compliance, EDI capability, and acceptance of a 3 percent administrative fee on all purchases. The RFP does not identify specific set-aside restrictions or dollar values. Geographic activity centers on Minnesota and participating states including Oregon; the cooperative purchasing model extends procurement reach across multiple state and local jurisdictions simultaneously.
