UNSPSC 12352400: Mixtures

UNSPSC 12352400 Mixtures is a Class code that captures state and local procurement of treatment chemicals, cleaning compounds, and specialized chemical solutions for municipal water systems, wastewater facilities, fleet and facility maintenance, and institutional operations. The solicitations posted since late January 2026 show heavy demand for water treatment chemistry (aluminum sulfate, sodium hypochlorite, magnesium hydroxide, liquid ammonium sulfate, and corrosion inhibitors); wastewater odor and corrosion control additives (ferrous iron salt, ferrous chloride, and bioxide); janitorial and facility cleaning chemicals; and fleet and transit maintenance fluids. Issuing bodies span state universities (Texas A&M University Procurement Services), municipal water departments (City of Santa Cruz Water Department, City of Griffin Water, City of Temple Water), wastewater utilities (City of Tallahassee, Douglasville-Douglas County Water and Sewer Authority, Great Lakes Water Authority), counties (Volusia County Water Resources, Indian River County, Clackamas County), cities (Dallas, Meriden, Dublin, Flowery Branch), school districts (Colquitt County School Nutrition, Clayton County Public Schools, Pinellas County Schools), and specialized districts (Eastern Municipal Water District, Solid Waste Authority of Palm Beach County). Water treatment and wastewater chemicals dominate the recent posting volume, with recurring buyers across Florida, Georgia, Connecticut, California, Michigan, Ohio, and Texas.

Recent representative opportunities include the City of Milpitas (California) IFB 26-229 for blanket MRO supply categories (posted July 10, 2026; due July 23, 2026) covering maintenance supplies, fleet supplies, and facility chemicals with local preference and prevailing wage compliance; the City of Dallas ITB BR2600030262 for thirty-six-month sewer odor and corrosion control services (posted May 21, 2026; due June 26, 2026) with $10 million estimated value and mandatory SBE participation goals; the City of Tallahassee IFB 067-26-CPW for magnesium hydroxide slurry supply (posted May 1, 2026; due June 16, 2026) for a five-year requirements contract with local vendor preference available; the City of Santa Cruz IFB WT-0310 for liquid aluminum sulfate (posted June 18, 2026; due June 17, 2026) with $130,000 estimated annual spend; and Colquitt County Schools IFB for kitchen chemicals and janitorial supplies (posted May 20, 2026; due June 15, 2026). Most water utility procurements require NSF 60 or ANSI/NSF 60/61 certification, AWWA compliance, delivered pricing inclusive of freight, and delivery within 48–72 hours of order. Contract terms typically run one to five years, with firm pricing for year one and limited annual adjustments thereafter tied to CPI, Producer Price Index, or documented cost increases. Competitive pressure is high — many jurisdictions award to multiple vendors by line item or reserve secondary awards for supply continuity.
