UNSPSC 51191600: Electrolytes

UNSPSC 51191600 Electrolytes, a Class code, encompasses chemical products and solutions used in municipal water treatment, wastewater management, and specialized healthcare delivery. Recent state and local opportunities reveal the code spans electrolyte and chemical commodities including sodium bisulfite for water pollution control, parenteral nutrition and intravenous solutions for correctional healthcare, and control valves with electrolyte-compatible specifications for wastewater treatment systems. Issuing bodies include city utilities (municipal water pollution control facilities), state correctional departments procuring healthcare products for incarcerated populations, and county governments managing wastewater infrastructure. The scope reflects functional purchasing of chemical reagents and related equipment and services to support permit compliance, patient care, and treatment-plant operations rather than a single homogeneous commodity class.

Recent activity spans Florida, Washington, and Connecticut. The City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical supply to its Water Pollution Control Facility with bids due July 29, 2026. Broward County, Florida posted an RFI on September 18, 2026 (responses due September 29, 2026) seeking alternative suppliers or equivalent products for DeZurik/APCO valves with electric actuators and SCADA compatibility for wastewater sludge thickening and digestion, currently supplied sole-source by Controls Specialties, Inc. The Washington State Department of Corrections issued an RFQ on September 8, 2026 (responses due October 7, 2026, with a pre-bid conference on September 23, 2026) for parenteral products and services including TPN, PPN, and IV solutions for eight correctional facilities across three regions, with DOC planning to award up to three contractors per region and a contract term running November 26, 2026 through June 30, 2030. The Washington procurement emphasizes set-aside goals for small, minority-owned, women-owned, and veteran-owned businesses and requires 24-hour delivery for specialized nutrition preparations.
