UNSPSC 51341504 Fosfonet is a Commodity code under which state and local governments procure pharmaceutical products, specifically antimicrobial and emergency-response medications through both piggyback cooperative purchasing agreements and direct competitive solicitations. The scope of work encompasses the supply and delivery of branded or generic pharmaceutical formulations—including antibiotics such as Doxycycline Hyclate and Ciprofloxacin Hydrochloride, as well as emergency naloxone kits and drug deactivation systems—to public health departments, county health agencies, and community health facilities. Issuing bodies under this code include state health departments and county health authorities managing public health inventory and emergency preparedness initiatives. Buyers are typically centralized procurement offices acting on behalf of health and human services departments or emergency management programs.

Recent activity spans Illinois and Florida, with the Illinois Department of Public Health awarding a $2,999,999.11 three-year piggyback contract to Chartwell Rx LLC through the MMCAP Infuse consortium (Bid 26-482DPH-PREPD-B-53392, completed August 2026) for supply of Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets with 12-month initial term and two renewal options. Seminole County, Florida released an IFB (26IFB60459723LAS, due July 26, 2023) for annual procurement of 1,900 units of naloxone and 800 safe drug deactivation systems with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida, requiring vendors to cover all shipping and delivery costs. Both opportunities require E-Verify compliance and drug-free workplace certification; the Seminole County procurement includes potential FEMA funding with associated federal compliance obligations. Cooperative purchasing pathways such as MMCAP Infuse represent a significant volume channel for this commodity code.
