UNSPSC 51283610: Rifamycin s

This classification denotes an antitubercular agent with the molecular formula C37H45NO12, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier PI53N820JV, chemically known as 1,4-dideoxy-1,4-dihydro-1,4-dioxorifamycin, but more generally known as rifamycin s, which bears US NIH Compound Identifier 5475445. European Medicines Agency schedules rifamycin s or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10310MIG. Most nations, for tariff purposes, schedule rifamycin s under HS 29419000.

UNSPSC 51283610 Rifamycin S is a Commodity code for antimicrobial pharmaceutical products, though the recent state and local opportunities tagged under it reflect a broader pattern of state and county procurement of essential medications and public health supplies rather than rifamycin specifically. State and local health departments, counties, and community health agencies solicit pharmaceutical supplies—including antibiotics, opioid-reversal agents, and drug disposal systems—through piggyback cooperative purchasing vehicles and competitive sealed bidding. The Illinois Department of Public Health and Seminole County, Florida represent the kinds of issuing bodies active in this space: state health departments managing disease preparedness and emergency supply contracts, and county health and community services offices procuring medications and harm-reduction equipment for public health initiatives.

Recent activity concentrates in Florida and Illinois, with the most visible solicitations in mid-2026. The Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical warehouse piggyback contract to Chartwell Rx LLC through the MMCAP Infuse consortium on August 28, 2026 (closed), supplying Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets over a 12-month initial term with renewal options; response had closed by September 11, 2026. Seminole County, Florida released an IFB on June 30, 2026 (IFB 60459723LAS) seeking 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to its community health building in Sanford, with response due by July 26, 2023—though that response date appears inconsistent with the posting date and likely reflects a data-entry error in the source. Both solicitations emphasize pharmaceutical inventory management, fixed-term contracts with renewal pathways, and compliance with standard procurement controls including drug-free workplace certification and E-Verify.
