UNSPSC 51283600: Rifamycin antibacterials

This classification denotes a group of anti-bacterial agents characterized by a chromophoric naphthohydroquinone group spanned by an aliphatic bridge not previously found in other known anti-bacterial agents, and they have been isolated from fermentation broths of streptomyces mediterranei.

UNSPSC 51283600 Rifamycin antibacterials is a Class code under which state and local governments procure antibiotic pharmaceuticals, including rifamycin-class drugs and related antibacterial products. However, the recent state and local contract opportunities tagged to this code show minimal alignment with its nominal scope. The Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC covering Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither of which are rifamycins—and Seminole County, Florida issued an IFB for Naloxone and Safe Drug Deactivation Systems, which fall outside antibiotic procurement entirely. The code shows little relevant recent activity tied to its actual commodity definition.

The geographic spread of tagged opportunities spans Illinois and Florida, though the opportunities themselves do not substantively reflect rifamycin purchasing. The Illinois award, completed August 28, 2026, was an IFB process with Chartwell Rx LLC as the selected vendor under a 12-month initial term with two renewal options. The Seminole County solicitation (IFB 60459723LAS), posted June 30, 2026, with a July 26, 2023 response deadline, sought quarterly deliveries of naloxone and drug deactivation systems with a two-year initial term and one-year renewal option. Absent recent open solicitations specifically targeting rifamycin antibacterials or other products squarely within the code's scope, pursuit strategy should focus on clarifying how this code aligns with actual state and local antibiotic procurement workflows.
