UNSPSC 51283400: Penicillins

This classification denotes a group of antibiotics that contain 6-aminopenicillanic acid (hence the name PENICILLIN) with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.

UNSPSC 51283400 Penicillins is a Class code that, in recent state and local procurement activity, encompasses pharmaceutical procurement for public health and emergency response functions. The recent opportunities show state and local governments buying antibiotics and opioid-reversal agents through cooperative purchasing arrangements and direct competitive bidding. Issuing bodies include state health departments and county public health authorities, procuring via piggyback contracts through multi-agency consortiums and standard invitation-for-bid processes to supply their community health and emergency management programs.

Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026, for Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets under a 12-month initial term with two optional renewal years. Seminole County, Florida posted an IFB on June 30, 2026, for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida, with a July 26, 2026, response deadline. Recent activity concentrates in the Southeast and Midwest, with both opportunities using standard competitive procurement vehicles and requiring vendors to handle delivery costs and meet standard contractor compliance requirements including drug-free workplace certification and E-Verify.
