About UNSPSC 51283501

UNSPSC 51283501 Cloxacillin is a Commodity code representing individual pharmaceutical products, but the recent state and local opportunities tagged under it show little activity directly aligned with cloxacillin procurement. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract through the MMCAP Infuse consortium to Chartwell Rx LLC on August 28, 2026 for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets — distinct antibiotic products outside the cloxacillin scope. Seminole County, Florida released an IFB on June 30, 2026 seeking 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually, a public health supply entirely unrelated to cloxacillin. State and local procurement under this code appears limited; the two recent opportunities show tagged mismatches rather than active cloxacillin demand.

The Illinois contract award is a completed transaction (not an open solicitation) valued at $2,999,999.11 over 12 months with two one-year renewal options, using an IFB process with no set-asides or domestic preferences applied. The Seminole County opportunity, posted June 30, 2026 with a response deadline of July 26, 2023 (a date inconsistency suggesting data entry error), calls for quarterly deliveries to a single location in Sanford, Florida with a two-year initial term and one-year renewal option. Neither opportunity directly reflects cloxacillin procurement activity; the code shows little relevant recent state and local buying signal.
