UNSPSC 51204000: Immunosupressant pyridines

This classification denotes substances that consist of hexahydropyridines, called pyridines, that reduce a human host's humoral and/or cell-mediated defense mechanisms against deviant native cells, foreign organisms, or foreign substances (the human immune response and system thereof), thus the term IMMUNOSUPPRESSANT PYRIDINES.

UNSPSC 51204000 Immunosuppressant pyridines, a Class code, shows limited alignment between its nominal scope and recent state and local procurement activity. The four opportunities posted since January 2026 span naloxone and drug deactivation systems, direct-to-manufacturer prescription programs, medical and first aid supplies for fire rescue, and generic multi-source pharmaceuticals and OTC products—a mix that includes emergency medical supplies, pharmacy benefit management arrangements, and broad pharmaceutical procurement, but not immunosuppressant pyridines specifically. State and local buyers posting under this code include county health departments (Seminole County, Florida), state health agencies (Texas Health and Human Services Commission), municipal fire departments (City of Tampa), and cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance, serving Minnesota and Oregon).

Recent opportunities cluster in the Southeast and Upper Midwest, with posting dates concentrated in the first half of 2026. Seminole County, Florida posted IFB 60459723LAS on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with a July 26, 2023, response date, for quarterly delivery to the Seminole County Community Health Building in Sanford. The City of Tampa issued IFB 26P00145 on March 25, 2026, for medical and first aid supplies (169 line items, estimated contract value $700,000) for the Tampa Fire Department Rescue Division, with response due March 13, 2026, and a 5 percent bid discount set-aside for certified Small Local Business Enterprises. The Texas Health and Human Services Commission released RFI HHS0017013 on April 3, 2026, seeking vendor information on direct-to-manufacturer prescription programs, marking early-stage market intelligence rather than formal competitive procurement. The Minnesota Multistate Cooperative Purchasing Alliance posted RFP S1070000015802 on January 20, 2026, establishing multiple contracts for generic multi-source pharmaceuticals and OTC products across state and local facilities, with responses due March 26, 2026. The divergence between the code's nominal pharmaceutical scope and the specific products being solicited suggests the code may be misaligned with actual procurement activity in state and local systems.
