UNSPSC 51281503 Amithiozone or thiacetazone is a Commodity code covering specific pharmaceutical active ingredients, but the recent state and local opportunities tagged under it show minimal alignment with the code's nominal scope. The Illinois Department of Public Health's awarded piggyback contract through MMCAP Infuse with Chartwell Rx LLC supplied Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither of which is amithiozone or thiacetazone. Seminole County, Florida's competitive bid sought Naloxone and Safe Drug Deactivation Systems, also outside the code's scope. State and local health departments and county procurement offices do acquire pharmaceuticals and medical countermeasures through piggyback cooperative purchasing vehicles and competitive IFBs, but this code shows little recent activity tied to its actual pharmaceutical category.

Activity appears concentrated in Florida and Illinois based on the recent-opportunity record, though the sample is too small to characterize geographic spread with confidence. The Illinois contract, a completed $2,999,999.11 award over three years with 12-month initial and renewal terms, illustrates state health agency reliance on consortium purchasing. Seminole County's IFB, posted June 30, 2026 with a July 26, 2023 response date, called for 1,900 units of Naloxone and 800 deactivation systems annually with quarterly deliveries and potential FEMA funding. Neither opportunity is an open solicitation—the Illinois award is closed and the Seminole County record is dated. The code does not currently reflect active competitive opportunities; firms should monitor for misclassified pharmaceutical and medical countermeasure procurements or verify whether this code sees meaningful use in their target jurisdictions.
