UNSPSC 51283224 Tylosin phosphate is a Commodity code that covers a single veterinary antibiotic product line, yet the recent state and local contract opportunities tagged under it do not reflect actual procurement of tylosin phosphate. Instead, the opportunities present describe pharmaceutical purchases wholly unrelated to this code's nominal scope — an Illinois Department of Public Health piggyback contract for human antibiotics (Doxycycline and Ciprofloxacin) and a Seminole County, Florida competitive bid for Naloxone and drug deactivation systems for community health initiatives. The code shows little relevant recent activity aligned with its product definition, suggesting either mislabeling at the time of opportunity posting or a data artifact in the state and local procurement system's taxonomy assignment.

The single award identified — the Illinois Department of Public Health piggyback pharmaceutical warehouse order through the MMCAP Infuse consortium to Chartwell Rx LLC for $2.999 million over a three-year term including renewals (IFB 26-482DPH-PREPD-B-53392, closed August 28, 2026) — involved human-use antibiotics, not veterinary pharmaceutical products. The Seminole County opportunity (IFB 60459723LAS, posted June 30, 2026, with a July 26, 2023 response date now expired) pursued naloxone and drug deactivation equipment, also outside this code's scope. No active solicitations, repeat buyers, or geographic concentration pattern emerges from the available records. Business development professionals should treat this code as inactive for state and local procurement purposes and verify any future opportunities against the actual product specifications rather than relying on the UNSPSC assignment alone.
