UNSPSC 12163902: Scale removers or converters

UNSPSC 12163902 Scale removers or converters (Commodity) encompasses water treatment chemicals purchased by state and local water and wastewater utilities, primarily aluminum sulfate (alum), sodium bisulfite, sodium hypochlorite, chlorine, lime slurry, hydrofluosilicic acid, magnesium hydroxide, and related treatment compounds used for coagulation, disinfection, pH adjustment, and corrosion or odor control in drinking water and wastewater systems. City water departments, county water authorities, independent school districts, and municipal wastewater treatment facilities dominate the issuing-body mix, with utilities in Georgia, Texas, and Florida generating the most recent procurement activity. All chemicals solicited must carry NSF 60 certification for drinking water use or equivalent regulatory approval; delivery within 48–72 hours of order is standard, with F.O.B. destination pricing and firm unit pricing for the initial contract term typical across opportunities. Contracts commonly run one to five years with optional renewal periods.
