UNSPSC 51191563 Quincarbate, a Commodity code, covers chemical products used in municipal water treatment, wastewater management, and correctional healthcare operations. State and local governments procure sodium bisulfite for water pollution control facilities, parenteral nutrition and intravenous solutions for detention healthcare, and specialized valves with associated parts and repair services for wastewater treatment compliance. Issuing bodies span municipal water utilities, county wastewater authorities, and state correctional departments. Work typically involves chemical supply with firm pricing and delivery schedules, medical-grade pharmaceutical preparation and distribution with strict time-of-delivery requirements, and technical maintenance services for equipment requiring SCADA compatibility and preventive service programs.

Recent activity appears concentrated in Florida and Washington. The City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical 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 (responses due September 29, 2026) to assess whether DeZurik/APCO valves, parts, and repair services are available from multiple providers or if alternatives meeting wastewater treatment permit compliance could substitute for the current sole-source arrangement with Controls Specialties, Inc. The Washington State Department of Corrections issued an RFQQ for parenteral products, services, and equipment across eight correctional facilities in three regions with responses due October 7, 2026 and a pre-bid conference on September 23, 2026; the department encourages participation from small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%) and has set an aspirational 5% small and diverse business goal with a subcontractor inclusion plan requirement. The initial DOC contract term runs November 26, 2026 through June 30, 2030 with possible award to up to three bidders per region.
