UNSPSC 12352305: Inorganic hydroxides

UNSPSC 12352305 Inorganic hydroxides (Commodity) encompasses chemical compounds—primarily calcium chloride and magnesium hydroxide slurry—that state and local governments procure for ice control, wastewater treatment, hydrogen sulfide and corrosion control, and related infrastructure applications. Recent solicitations show municipalities and regional utilities buying liquid calcium chloride for street de-icing, magnesium hydroxide slurry for wastewater odor and corrosion mitigation, and related chemical additives. Issuing bodies include city public works departments, county water resources and environmental utilities, regional water authorities, and county maintenance operations. The City of Detroit, City of Tallahassee, Gwinnett County Board of Commissioners, Pasco County, and the Brazos River Authority have all posted recent opportunities under this code or closely aligned chemical specifications. Specifications are technical and demanding—suppliers must meet precise pH, solids composition, particle size, viscosity, and viscosity tolerances, hold relevant industry certifications including ANSI/NSF Standard 60 where required, and demonstrate minimum three to five years of experience providing the specific product to municipal or industrial customers. Most opportunities require F.O.B. Destination pricing with all transportation and labor embedded, firm unit pricing for initial contract years, and performance security or insurance ranging from $1 million to $2 million in general liability coverage.
