UNSPSC 51284506 Colistin sulfate is a Commodity code that does not align with the recent state and local contract opportunities posted under its designation. The opportunities instead reflect purchases of naloxone, emergency medical supplies, over-the-counter pharmaceuticals, and direct-to-manufacturer prescription programs—none of which involve colistin sulfate, an antibiotic veterinary or aquaculture pharmaceutical. The mismatch suggests either a data tagging error in the procurement system or that colistin sulfate itself sees minimal state and local solicitation activity at present. State and local buyers posting under this code appear to span county health departments (Seminole County, Florida), municipal fire services (Tampa Fire Department via the City of Tampa), state health and human services commissions (Texas HHS), and multistate cooperative purchasing alliances (MMCAP, administered by Minnesota Department of Administration with Oregon participation). None of these issuing bodies have placed recent competitive solicitations specifically for colistin sulfate or products matching its therapeutic scope.

Recent opportunities tagged to this code include Seminole County's IFB for naloxone and drug deactivation systems (1,900 units of naloxone, 800 deactivation units annually, due July 26, 2023, with quarterly delivery to Sanford, Florida); the City of Tampa's ITB for medical and first aid supplies for its Fire Department Rescue Division (169 line items of emergency medical consumables, $700,000 estimated value, sealed bids due March 13, 2026, sheltered for certified Small Local Business Enterprises with a 5 percent bid discount not to exceed $10,000); MMCAP's RFP for generic multi-source pharmaceuticals and OTC products (proposals due March 26, 2026, covering Minnesota, Oregon, and participating jurisdictions, supplied through three authorized wholesalers with 75 percent evaluation weight on price competitiveness); and the Texas HHS Commission's RFI on direct-to-manufacturer prescription programs (posted April 3, 2026, exploratory market intelligence gathering on vendor capacity for self-insured group health plan contracting). The geographic spread across Florida, Texas, Minnesota, and Oregon reflects activity among state and local health and emergency services buyers, though none of the posted opportunities directly procure colistin sulfate or related veterinary antimicrobials.
