UNSPSC 51191930: Niacinamide hydrochloride

This classification denotes a b vitamin with the molecular formula C6H6N2O.CLH, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4D16EOF1QW. Most nations, for tariff and trade purposes, schedule niacinamide hydrochloride under HS 29362900. As of Q4 2014, NIACINAMIDE HYDROCHLORIDE remains US FDA's Preferred Term for this commodity. SMILES: C1CC(CNC1)C(=O)N.CL.

UNSPSC 51191930 Niacinamide hydrochloride is a Commodity code that describes chemical supply for water treatment and pharmaceutical manufacturing operations procured by state and local government facilities. The recent opportunities posted under this code show a sharp divergence: the City of Meriden solicited sodium bisulfite for municipal water pollution control, while the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) issued a Request for Proposal for generic multi-source pharmaceuticals and over-the-counter products distributed across participating state and local government facilities in Minnesota and Oregon. The scope encompasses chemical additives and pharmaceutical compounds supplied to public water utilities, health departments, and institutional healthcare providers, with vendors required to meet FDA compliance, cGMP certification, and chain-of-custody standards including Drug Supply Chain Security Act compliance. State and local issuing bodies soliciting under this code include municipal water utilities, state cooperative purchasing alliances, and health agencies; MMCAP appears as a repeat platform aggregating demand across multiple member jurisdictions.

The code shows activity in Connecticut and Minnesota with multi-state reach through cooperative purchasing. The City of Meriden (Connecticut) issued IFB B027-15 for sodium bisulfite delivery by July 29, 2026, with unit-cost pricing evaluation and bonding requirements. MMCAP's RFP for generic pharmaceuticals and OTC products, posted January 20, 2026 with response due March 26, 2026, targets manufacturers supplying through three authorized wholesalers (AmerisourceBergen/Cencora, Cardinal Health, and Morris & Dickson) with products effective July 1, 2026; evaluation weights price competitiveness at 75 percent, with vendors required to maintain commercial general liability of $5,000,000 per occurrence and comply with a 3 percent administrative fee structure. The mismatch between the code's niacinamide-hydrochloride nomenclature and the actual solicitations for sodium bisulfite and broad-spectrum pharmaceuticals suggests the code's application at the commodity level does not cleanly track current state and local buying patterns in this chemical and pharmaceutical supply category.
