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, but the recent opportunities posted under it reflect a mismatch: state and local governments are actually soliciting industrial chemicals, pharmaceutical supplies, and equipment for water treatment and correctional healthcare — none of which are niacinamide hydrochloride or pharmaceutical-grade niacin compounds. The three recent opportunities span chemical supply for municipal water treatment (sodium bisulfite), parenteral nutrition and intravenous solutions for incarcerated individuals, and specialized valve parts and repair services for wastewater treatment systems. The issuing bodies include municipal water and wastewater authorities, state correctional departments, and county purchasing offices managing infrastructure and healthcare operations.

Recent activity is geographically dispersed across Florida, Washington, and Connecticut. The Washington State Department of Corrections issued an RFQQ for parenteral products, services, and equipment due October 7, 2026, seeking parenteral nutrition solutions, intravenous products, and related supplies to eight correctional facilities statewide with procurement of multiple contractors and a contract term running through June 30, 2030; the solicitation carries set-asides for small businesses (25%), minority-owned (10%), women-owned (6%), and veteran-owned (5%) suppliers. The City of Meriden, Connecticut posted an IFB for sodium bisulfite chemical supply for its Water Pollution Control Facility with a July 29, 2026 due date. Broward County, Florida issued a Request for Information on DeZurik/APCO valves, parts, and repair services due September 29, 2026, to evaluate alternatives to the incumbent sole-source provider, with emphasis on SCADA-compatible equipment and preventive maintenance capabilities for wastewater treatment compliance. The code shows limited relevance to niacinamide hydrochloride procurement specifically; vendors sourcing under this code should verify whether opportunities are properly categorized or represent a data-entry classification issue.
