UNSPSC 12000000: Chemicals including Bio Chemicals and Gas Materials

This segment includes inorganic and organic chemicals and compounds in solid, liquid or gaseous form used in an industrial or manufacturing process

UNSPSC 12000000 Chemicals including Bio Chemicals and Gas Materials is a Segment code under which state and local governments procure water treatment and wastewater treatment chemicals, dust control products, and specialty chemical supplies for municipal and utility operations. Recent opportunities show active procurement of sodium hypochlorite and caustic soda for water disinfection, liquid emulsion polymers for biosolids dewatering, ferric compounds for coagulation, activated carbon for filtration, rock salt and calcium chloride for de-icing, and dust palliatives for air quality compliance. Issuing bodies include water and wastewater utilities, municipal public works departments, county environmental services agencies, school districts, transit authorities, and special-purpose water districts. The Maryland Environmental Service, North Texas Municipal Water District, and various Connecticut municipalities appear repeatedly as active buyers. Work is heavily concentrated in water treatment plant operations, wastewater treatment facility maintenance, and highway/facility de-icing programs.

The code shows robust recent activity across Arizona, Connecticut, Maryland, Texas, Florida, Pennsylvania, and California, with the highest concentration in the Northeast and along the Gulf Coast. Representative recent opportunities include the City of Scottsdale RFP 27RFP114 (November 16, 2026 response deadline) for sodium hydroxide and hydrochloric acid delivery and standby operator services at a groundwater treatment facility; Charles County Government RFQ 26-044 (June 3, 2026 deadline) for multiple water and wastewater treatment chemicals including ferric chloride, liquid aluminum sulfate, sodium hypochlorite, and sodium bisulfite on an as-needed basis; the Metropolitan District Connecticut ITB 2026B-17 (August 18, 2026 deadline) for design and fabrication of fiberglass reinforced plastic tanks for sodium hypochlorite and sodium hydroxide storage; and the North Texas Municipal Water District's sealed bid solicitations for liquid ferric sulfate (August 6, 2026), aluminum chlorohydrate (July 29, 2026), and liquid emulsion cationic polymer (July 15, 2026). Many utilities employ Small Business Reserve set-asides, require Build America Buy America Act compliance for specific products, and impose strict delivery schedules tied to treatment facility operating hours and chemical usage cycles.
