UNSPSC 51281681: Viomycin sulfate

This classification denotes an antitubercular agent, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier LKO141R05V. European Medicines Agency schedules Viomycin sulfate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05106MIG. Viomycin sulfate generally arises in the molecular formula C25H43N13O10.H2O4S. The term 'viomycin sulfate' is a Japanese Accepted Name designation. Most nations, for tariff and trade purposes, schedule viomycin sulfate under HS 29419000 and SITC 54139.

As of Q4 2014, VIOMYCIN SULFATE remains US FDA's Preferred Term for this commodity. Viomycin sulfate bears US NLM identifiers UMLS ID C1321956 and NCI Concept Code C66655. SMILES: C1[C@@H](N=C(N[C@H]1O)N)[C@H]2C(=O)NC[C@@H](C(=O)N[C@H](C(=O)N[C@H](C(=O)N/C(=C\NC(=O)N)/C(=O)N2)CO)CO)NC(=O)C[C@H](CCCN)N.OS(=O)(=O)O.

UNSPSC 51281681 Viomycin sulfate (Commodity) does not align with recent state and local contract activity in the source material. The four opportunities posted between January and June 2026 involve naloxone and drug deactivation systems, direct-to-manufacturer pharmacy programs, emergency medical and first aid supplies for fire rescue, and generic multi-source pharmaceuticals and OTC products through cooperative purchasing—none of which reference viomycin sulfate or the narrow antibiotic scope the code nominally implies. The mismatch suggests the code either sees minimal relevant procurement activity or that state and local buyers tag such purchases under broader pharmaceutical or medical supply classifications rather than this specific commodity designation.

The issuing bodies in the sample represent diverse public procurement: a county health department (Seminole County, Florida), a state health agency conducting market research (Texas Health and Human Services Commission), a city fire department (City of Tampa), and a multistate cooperative purchasing consortium (Minnesota Multistate Cooperative Purchasing Alliance, serving state and local facilities across multiple states including Oregon). Geographic spread includes Florida, Texas, Minnesota, and Oregon. Because none of these opportunities involve viomycin sulfate or antibiotics in the penicillin-derived family this code describes, a business development professional should treat the code as showing no actionable recent state and local activity and focus procurement development resources on broader pharmaceutical-supply or medical-device codes where actual buying is documented.
