UNSPSC 51281656: Neomycin b sulphate

This classification denotes an aminoglycoside antibiotic with the molecular formula C23H46N6O13.3H2O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Y3720KZ4TQ, chemically known as neomycin b, sulfate (salt), but more generally known as neomycin b sulphate, which bears US NIH Compound Identifier 197162. European Medicines Agency schedules neomycin b sulphate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03406MIG.

Most nations, for tariff purposes, schedule neomycin b sulphate under HS 29419000. SMILES: C1[C@H]([C@@H]([C@H]([C@@H]([C@H]1N)O[C@@H]2[C@@H]([C@H]([C@@H]([C@H](O2)CN)O)O)N)O[C@H]3[C@@H]([C@@H]([C@H](O3)CO)O[C@@H]4[C@@H]([C@H]([C@@H]([C@@H](O4)CN)O)O)N)O)O)N.OS(=O)(=O)O.OS(=O)(=O)O.OS(=O)(=O)O.

UNSPSC 51281656 Neomycin B Sulphate is a Commodity code that nominally covers a specific antibiotic pharmaceutical ingredient, yet recent state and local procurement activity under this code shows little direct alignment with the named product. The two most recent opportunities tagged to this code involve naloxone procurement and a pharmaceutical warehouse piggyback contract for doxycycline and ciprofloxacin — neither of which is neomycin B sulphate. State and local issuing bodies appear to use this code inconsistently or as a catch-all for pharmaceutical and medical supply acquisitions rather than as a precise descriptor of active pharmaceutical ingredients. The Illinois Department of Public Health and Seminole County, Florida are the two recent buyers identified, representing state health departments and county health authorities as the primary issuing bodies for pharmaceutical and emergency medical supply procurement under this code.

Geographic activity centers on Illinois and Florida based on the most recent opportunities. The Illinois Department of Public Health executed a piggyback pharmaceutical warehouse contract through the MMCAP Infuse consortium to Chartwell Rx LLC for $2,999,999.11 over 12 months with two renewal options, awarded under Invitation for Bid 26482DPHPREPDB53392 on August 28, 2026. Seminole County, Florida posted an IFB (IFB60459723LAS) on June 30, 2026, to procure 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries, due July 26, 2023 — though that due date appears to be a data error in the source. Neither opportunity directly solicits neomycin B sulphate, signaling a code-to-opportunity mismatch rather than active market demand for the named commodity.
