UNSPSC 41104201: Water purification reagents

UNSPSC 41104201 Water purification reagents is a Commodity code covering chemical inputs and treatment compounds used in municipal water and wastewater systems. State and local governments buy chlorination reagents (sodium hypochlorite, liquid chlorine, sodium chlorite), coagulation and flocculation chemicals (aluminum sulfate, ferric chloride, polymers), pH adjustment compounds (sodium hydroxide, hydrated lime, soda ash), specialized treatment agents (powdered activated carbon, potassium permanganate, sodium bisulfite), and proprietary OEM replacement parts for treatment equipment under this code. Issuing bodies include city water and wastewater departments, county water authorities, and municipal treatment facilities. Recent solicitations show water utilities procuring both commodity chemicals in volume and specialized OEM parts for legacy treatment equipment; the code spans both standardized reagent procurement and sole-source parts acquisitions where equipment lock-in exists.
