UNSPSC 51282300: Erythromycins

This classification denotes an antibiotic variety based on a bacteriostatic produced from Streptomyces erythreus, hence the name ERYTHROMYCIN, and of which Erythromycin A is the major active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.

UNSPSC 51282300 Erythromycins is a Class code that nominally covers erythromycin antibiotics, but recent state and local procurement activity under this code shows minimal alignment with that scope. The two most recent opportunities posted under this code involve pharmaceutical procurement through warehouse piggyback arrangements and emergency-response supplies, neither of which centers on erythromycin products themselves. The Illinois Department of Public Health awarded a piggyback pharmaceutical contract through the MMCAP Infuse consortium for antibiotic tablets (Doxycycline Hyclate and Ciprofloxacin Hydrochloride), while Seminole County, Florida issued an IFB for Naloxone and drug deactivation systems. These solicitations reflect broader state and local demand for pharmaceutical supplies and emergency-response products procured through cooperative purchasing vehicles and competitive bidding, though the specific erythromycin commodity appears underrepresented in current activity.

Recent opportunities have emerged from a county health department and a state public health agency, both operating through established procurement frameworks. The Illinois Department of Public Health completed an award to Chartwell Rx LLC on August 28, 2026, for $2,999,999.11 over the contract life (12 months with two renewal options) through an Invitation for Bid process; Seminole County, Florida issued its IFB (60459723LAS) on June 30, 2026, with a response deadline of July 26, 2026 (later updated in the source), seeking quarterly deliveries of naloxone and deactivation systems. The geographic spread is limited to Florida and Illinois in the recent record. Bidders should note that cooperative purchasing consortia like MMCAP Infuse are actively used by state health agencies to manage pharmaceutical supply chains, and that competitive IFB processes with fixed-fee pricing and specific delivery requirements drive contract awards. The mismatch between the code's nominal erythromycin scope and actual procurement activity suggests this code may not be the primary classification for current state and local antibiotic or pharmaceutical sourcing.
