UNSPSC 51285805 Hexamine or methenamine is a Commodity code that in recent state and local procurement does not align with its nominal chemical classification. The recent opportunities posted under this code actually solicit naloxone and drug deactivation systems, medical and first aid supplies for emergency response, and pharmaceutical benefit program services — none of which are hexamine or methenamine products. State and local governments using this code classification appear to be procuring emergency medical supplies, community health support items, and pharmacy benefit administration services rather than the specific chemical compound the code nominally describes. The issuing bodies span county health departments (Seminole County, Florida), municipal fire and rescue divisions (City of Tampa), state health and human services agencies (Texas HHS Commission), and multistate cooperative purchasing organizations (Minnesota Multistate Cooperative Purchasing Alliance serving multiple states including Oregon). This mix suggests the code is applied across health and emergency-response jurisdictions of varying scale, though the small number of recent opportunities under this code indicates either light activity or substantial miscoding.

Recent activity clusters geographically in Florida, Texas, and Minnesota, with multistate cooperative participation. Seminole County, Florida issued IFB 60459723LAS in June 2026 for 1,900 units of naloxone and 800 safe drug deactivation systems annually, with quarterly deliveries and a response deadline of July 26, 2026, under a two-year term with one-year renewal option. The City of Tampa issued ITB 26P00145 in March 2026 for medical and first aid supplies (respiratory equipment, cardiac monitoring devices, airway supplies, gloves, bandaging materials, and oxygen delivery systems) for the Tampa Fire Department Rescue Division, with an estimated contract value of $700,000 and a sheltered-market set-aside for certified Small Local Business Enterprises offering a 5 percent bid discount not to exceed $10,000. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration, issued RFP S1070000015802 in January 2026 to establish multiple contracts for generic pharmaceuticals and OTC products from manufacturers, with proposals due March 26, 2026, requiring vendor compliance with cGMP, DSCSA, and specific insurance thresholds including $5 million commercial general liability per occurrence.
