UNSPSC 51162721 Mecysteine is a Commodity code that in practice encompasses pharmaceutical procurement by state and local health authorities, though recent activity under this specific code shows limited direct alignment with the nominal product. State and local governments use codes in this family to procure pharmaceutical products, including naloxone, generic multi-source medications, and over-the-counter products for public health, emergency response, and community health initiatives. Issuing bodies include county health departments, state pharmaceutical cooperative purchasing alliances, and regional health authorities. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, and county-level health procurement offices represent the primary institutional buyers visible in recent solicitations.

Recent activity centers in Florida and Minnesota. Seminole County, Florida issued an IFB (Solicitation Number IFB60459723LAS) on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually, with quarterly deliveries to the Seminole County Community Health Building and a response deadline of July 26, 2026. MMCAP issued an RFP (Solicitation Number S1070000015802) on January 20, 2026, for generic multi-source pharmaceuticals and OTC products across multiple participating state and local facilities, with responses due March 26, 2026 and contract effectiveness set for July 1, 2026. The MMCAP procurement requires vendors to work through three authorized wholesalers (AmerisourceBergen Drug Corporation/Cencora, Cardinal Health, and Morris & Dickson Co., LLC), maintain cGMP and DSCSA compliance, and carry $5 million commercial general liability coverage. Both solicitations emphasize standard state and local compliance requirements, including E-Verify certification and workers' compensation insurance. The code shows limited recent activity overall; opportunities are dispersed geographically rather than concentrated in a single region or repeat buyer.
