UNSPSC 51283223 Tilmicosin phosphate is a Commodity code representing specific pharmaceutical active ingredients and finished-form drugs purchased by state and local health departments and counties. The source records show state and local governments buying finished pharmaceutical products—antibiotics, opioid antagonists, and drug deactivation systems—through piggyback warehouse contracts and direct procurement to support public health, emergency response, and community health initiatives. Issuing bodies include state departments of public health and county health agencies, which source these products through competitive bidding processes and established pharmaceutical supply consortia to meet regulatory and operational requirements.

Recent activity appears geographically dispersed.
