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 is a Commodity code that nominally covers a specific antibiotic pharmaceutical product; however, the recent state and local procurement activity tagged under this code does not reflect purchases of viomycin sulfate itself. Instead, the opportunities show state and local agencies acquiring other pharmaceutical products — naloxone and drug deactivation systems for community health and emergency response, and antibiotic tablets (doxycycline and ciprofloxacin) through piggyback contracts. The code shows little relevant recent activity aligned with its stated scope. Issuing bodies in the source include a state health department (Illinois Department of Public Health) and a county government (Seminole County, Florida), both using established cooperative purchasing vehicles or competitive sealed bidding to acquire pharmaceuticals. The mix suggests state and local health agencies and public health authorities as the typical buyer base, though the misalignment between the code's nominal scope and the actual purchases limits confidence in the category's current applicability.

Geographic activity is evident in Illinois and Florida based on the recent opportunities. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract to Chartwell Rx LLC on August 28, 2026, valued at $2,999,999.11 over 12 months with two renewal options, through the MMCAP Infuse consortium using an Invitation for Bid process and the IFB notice type — this is a completed award, not an open solicitation. Seminole County, Florida released an IFB (number IFB60459723LAS) on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually, with a response deadline of July 26, 2026. Given the mismatch between the code's stated pharmaceutical and the work actually being sourced, pursuit of this code should be informed by direct confirmation that viomycin sulfate is relevant to a specific issuing body's procurement, rather than reliance on tagging alone.
