UNSPSC 51101643 Carbarsone is a Commodity code that in recent state and local procurement activity covers pharmaceutical products supplied through piggyback and cooperative purchasing arrangements, though the specific instances in the current record do not include carbarsone itself. 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 in August 2026 for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets under a 12-month initial term with two one-year renewal options; Seminole County, Florida issued an IFB in June 2026 for annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly deliveries and a two-year initial term plus one-year renewal option. State health departments and county health or community agencies are the primary issuing bodies under this code, typically procuring through cooperative purchasing vehicles, piggyback arrangements, or competitive sealed bids with fixed-fee pricing structures.

Recent activity appears concentrated in the South and Midwest, with documented solicitations from Illinois and Florida. The Illinois Department of Public Health contract, awarded on an IFB basis with response by September 11, 2026, demonstrates state-level pharmaceutical procurement at scale with multi-year renewal options and no set-aside requirements. The Seminole County solicitation, posted June 30, 2026 with a July 26, 2023 response date noted in the source, required unit pricing and included E-Verify compliance, drug-free workplace certification, and potential FEMA funding with associated federal regulatory compliance. Vendors responding to opportunities under this code should expect quarterly or periodic delivery schedules, inclusion of shipping in pricing, and standard commercial insurance and employment verification requirements.
