UNSPSC 51284910: Sulfadiazine/sulfamerazine/sulfamethazine

This classification denotes a combination drug defined by the U.S. Department of Veterans Affairs in its (VA's) National Drug File (NDF), which falls under VA Drug Class AM650. This VA Drug Class (AM650) classifies this compound as belonging to the group SULFONAMIDE/RELATED ANTIMICROBIALS.

UNSPSC 51284910 Sulfadiazine/sulfamerazine/sulfamethazine is a Commodity code covering pharmaceutical products, but the recent state and local opportunities posted under this code do not match its nominal scope. The Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical contract through the MMCAP Infuse consortium to Chartwell Rx LLC for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets, and Seminole County, Florida sought to procure Naloxone and drug deactivation systems. Neither opportunity involves sulfadiazine compounds or the sulfonamide antimicrobial class the code nominally describes. State and local procurement offices appear to be using this code to classify general pharmaceutical inventory and emergency-response drug supplies rather than the specific chemical formulation the code name indicates.

The issuing bodies soliciting under this code include state health departments and county public-health agencies. Recent activity concentrates in Florida and Illinois, with procurement driven by health-system inventory replenishment and community-health initiatives. The Illinois Department of Public Health's MMCAP Infuse piggyback award on August 28, 2026, with an initial 12-month term and two renewal options, represents a completed Invitation for Bid. Seminole County's June 30, 2026 IFB for 1,900 units of Naloxone and 800 deactivation systems annually, due July 26, 2026, illustrates county-level emergency-response procurement with quarterly deliveries and potential FEMA funding. The gap between the code's chemical specificity and the actual work being bought signals that firms pursuing pharmaceutical supply to state and local health agencies should verify code assignment in each RFP or IFB rather than rely on this code as a reliable filter.
