UNSPSC 51191800: Potassium salts

This classification denotes inorganic compounds that contain potassium as an integral part of the molecule.

UNSPSC 51191800 Potassium salts is a Class code that encompasses chemical supplies used in municipal and regional infrastructure operations, including water treatment and pollution control facilities, correctional healthcare systems, and wastewater treatment operations. State and local governments procure under this code a mix of specialty chemicals (sodium bisulfite for water pollution control, potassium-based compounds for process applications) and related services including technical support, maintenance, and compliance-driven equipment integration. Issuing bodies include municipal water and wastewater authorities, state correctional departments, and county public works and environmental health agencies. The recent opportunities show purchasing ranging from routine chemical supply contracts to more complex procurements bundling products with specialized technical services, delivery logistics, and regulatory compliance requirements, particularly where remote monitoring and SCADA integration are mandated.

Recent activity spans Florida, Washington, and Connecticut. Broward County, Florida issued a Request for Information in September 2026 (due September 29, 2026) on DeZurik/APCO valves, parts, and repair services for wastewater treatment, seeking to establish competition against an incumbent sole-source supplier; the RFI emphasized SCADA-compatible electric actuators, sludge thickening and digestion applications, and preventive maintenance programs. The Washington State Department of Corrections solicited parenteral products and services (RFQQK13020, RFQ due October 7, 2026) covering eight correctional facilities across three regions, requiring 24-hour delivery of specialized IV and nutrition solutions with fixed pricing through June 2030 and selective set-asides for small, minority-owned, women-owned, and veteran-owned businesses. The City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical supply (B027-15, due July 29, 2026) for its Water Pollution Control Facility with standard performance and payment bonds and fixed pricing. These opportunities reflect active procurement in water quality management and correctional healthcare, with emphasis on delivery performance, technical capability, and regulatory compliance in compliance-driven environments.
