UNSPSC 51283204 Tylosin, a Commodity code, represents pharmaceutical products and veterinary therapeutics that state and local governments procure through cooperative purchasing consortia and direct competitive bidding. Based on recent state and local solicitations, the code captures pharmaceutical warehouse supply contracts, emergency response medical countermeasures, and related drug-supply procurement. State and local issuers under this code include state health departments, county government agencies, and special-purpose public health entities. The Illinois Department of Public Health and Seminole County, Florida represent the recent buyer base, both using competitive bidding (Invitation for Bid and IFB processes) and cooperative purchasing vehicles such as MMCAP Infuse to source pharmaceutical inventories. Contracts typically run 12 to 24 months with renewal options and include requirements for electronic submission, drug-free workplace certification, E-Verify compliance, insurance coverage (workers' compensation and commercial general liability), and in some cases FEMA compliance obligations such as adherence to the Clean Air Act and Federal Water Pollution Control Act.

Recent opportunities show activity concentrated in Florida and Illinois. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract to Chartwell Rx LLC on August 28, 2026, through MMCAP Infuse for Doxycycline Hyclate and Ciprofloxacin Hydrochloride, a $2,999,999.11 award over three years selected via IFB (Bid Number 26-482DPH-PREPD-B-53392).

Both procurements reflect public-health demand for emergency response supplies and routine pharmaceutical inventory, with cooperative purchasing and direct competitive bidding as the primary acquisition mechanisms. No set-asides or preference programs were identified in these recent awards.
