UNSPSC 51191802 Potassium chloride is a Commodity code that in practice captures chemical supply procurement for state and local water treatment, wastewater handling, and healthcare delivery operations. Recent solicitations show potassium chloride and chemically related commodities (sodium bisulfite, parenteral nutrition solutions, and intravenous products) being procured by municipal water and wastewater utilities, state correctional healthcare systems, and county public works departments. The code encompasses both raw chemical supply for treatment processes and formulated products delivered under strict compliance and delivery-time requirements. Issuing bodies include city and county public works and environmental departments, state corrections agencies, and regional wastewater authorities. Contracts typically require fixed unit pricing, performance and payment bonding, specified insurance coverage with the jurisdiction named as additional insured, and documented supplier qualifications including business licensure and background clearance where healthcare or secure facility access is involved.

Recent activity spans Florida, Washington, and Connecticut. The City of Meriden, Connecticut issued an IFB for sodium bisulfite supply to its Water Pollution Control Facility with a due date of July 29, 2026. Broward County, Florida posted a Request for Information on September 18, 2026 (due September 29, 2026) to evaluate alternative suppliers of DeZurik/APCO valves and parts for wastewater treatment, with SCADA compatibility and remote operation capability required for permit compliance at municipal facilities. The Washington State Department of Corrections issued an RFQQ on September 8, 2026 (due October 7, 2026) for parenteral nutrition and intravenous products to be delivered to eight correctional facilities across three regions, with DOC anticipating multiple award and fixed pricing through June 30, 2030; the RFQ encourages small business (25%), minority-owned (10%), women-owned (6%), and veteran-owned business (5%) participation and requires a Subcontractor Inclusion Plan targeting disadvantaged businesses where economically feasible.
