UNSPSC 51283225 Tylosin tartrate is a Commodity code for a specific pharmaceutical active ingredient, but recent state and local procurement activity under this code shows little relevant activity aligned with the code's nominal scope. The two most recent opportunities posted under this code — an Illinois Department of Public Health pharmaceutical warehouse piggyback contract and a Seminole County, Florida procurement for naloxone and drug deactivation systems — do not involve tylosin tartrate. The Illinois contract, awarded to Chartwell Rx LLC in August 2026 for $2,999,999.11 over three years, supplies doxycycline hyclate and ciprofloxacin hydrochloride tablets; the Seminole County solicitation, posted June 2026, sought naloxone and safe drug deactivation systems for quarterly delivery to the county's community health building. Neither opportunity reflects procurement of tylosin tartrate itself, suggesting a potential misclassification or that state and local governments are not actively buying this ingredient under its designated code at present.

The mismatch between the code's intended scope and the actual opportunities tagged to it indicates that business development professionals should exercise caution before allocating resources to pursue work under this code. If tylosin tartrate procurement does occur in state and local markets — likely as a pharmaceutical warehouse or veterinary pharmaceutical supply item — it may be tagged to different UNSPSC codes or incorporated into broader pharmaceutical supply agreements that do not isolate this ingredient. Monitoring for clarification or reclassification of opportunities under this code, or confirming with issuing bodies directly that future solicitations will involve tylosin tartrate supply, would be prudent before committing pursuit resources.
