UNSPSC 51281679: Viomycin hydrochloride

This classification denotes the hydrochloride form of an antitubercular agent with the molecular structure C25H43N13O10, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier, YVU35998K5 chemically known as glycine, 3-amino-n-((3s)-3,6-diamino-1-oxohexyl)-l-alanyl-l-seryl-l-seryl-(2z)-3-((aminocarbonyl)amino)-2,3-didehydroalanyl-2-((4r,6s)-2-amino-1,4,5,6-tetrahydro-6-hydroxy-4-pyrimidinyl)-, (5->13)-lactam, (2s)-, but more commonly known as viomycin, which bears US NIH Compound Identifier 3032902.

UNSPSC 51281679 Viomycin hydrochloride is a Commodity code that nominally covers a specific antibiotic pharmaceutical product, but the recent state and local opportunities tagged under it bear little relevance to that scope. The most recent solicitations — including a Seminole County procurement for naloxone and drug deactivation systems, a Texas HHS Commission RFI on direct-to-manufacturer prescription programs, a Tampa Fire Department purchase of medical and first aid supplies, and a Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP for generic multi-source pharmaceuticals and OTC products — span a broad range of pharmaceutical procurement activity but do not specifically target viomycin hydrochloride or closely related tuberculosis treatments. State and local governments issuing under this code represent diverse jurisdictions: county health departments, state health and human services agencies, municipal fire departments, and cooperative purchasing alliances serving multiple states. The code shows minimal decision relevance for vendors focused on viomycin hydrochloride as a standalone therapeutic product.

Geographic activity spans Florida (Seminole County), Texas (Texas HHS Commission), Florida again (City of Tampa), and a multistate cooperative centered in Minnesota (MMCAP with participating members including Oregon). The most recent opportunity is Seminole County's IFB 60459723LAS, posted June 30, 2026, with a bid deadline of July 26, 2026, for annual procurement of 1,900 units of naloxone and 800 safe drug deactivation systems with quarterly deliveries; the City of Tampa's bid 26-P-00145, due March 13, 2026, for 169 line items of medical and first aid supplies estimated at $700,000.00 and restricted to certified Small Local Business Enterprises with a 5 percent bid discount; and MMCAP's RFP S1070000015802, due March 26, 2026, to establish multiple contracts for generic pharmaceuticals and OTC products with awards effective July 1, 2026. The code appears to be a misapplication of UNSPSC taxonomy to these procurements, and vendors evaluating this code should verify that viomycin hydrochloride is the actual product being sought before pursuing opportunities listed under it.
