UNSPSC 51283224 Tylosin phosphate is a Commodity code that in recent state and local procurement shows little activity aligned with its nominal scope. The code's name references a specific antibiotic compound used in veterinary and agricultural contexts, yet the recent opportunities tagged to this code encompass naloxone and drug deactivation systems, therapeutic pharmacy initiatives, emergency medical and first aid supplies for fire departments, and generic multi-source pharmaceuticals and OTC products—none of which are tylosin phosphate or related veterinary pharmaceuticals. The mismatch suggests that either the code was applied incorrectly to these solicitations or the state and local procurement system using this taxonomy has repurposed the code to capture a broader pharmaceutical or medical supply category than the code name implies.

The recent opportunities are issued by state health and human services agencies (Texas HHS Commission), county health departments (Seminole County, Florida), municipal purchasing offices (City of Tampa), and cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance serving multiple states including Oregon). These solicitations span from January 2026 through June 2026, with response dates through March 2026. Geographic activity centers on Florida, Texas, and Minnesota, with multi-state reach through cooperative purchasing. Representative opportunities include Seminole County's IFB for naloxone and drug deactivation systems (due July 26, 2023, with quarterly deliveries), the City of Tampa's sealed-bid medical and first aid supplies procurement for the Fire Department Rescue Division estimated at $700,000 and designated for certified Small Local Business Enterprises with a 5 percent bid discount (due March 13, 2026), and MMCAP's RFP for generic multi-source pharmaceuticals and OTC products distributed through authorized wholesalers effective July 1, 2026 (proposal deadline March 26, 2026). Given the code's apparent misalignment with the actual solicitations, this code warrants verification against issuer classification records before pursuing activity.
