UNSPSC 12163803: H2S absorbent

Hydrogen Sulfide absorbent scavenger used in the Oil & Gas Industry.

UNSPSC 12163803 Hydrogen Sulfide Control Service as a Commodity code names chemical products and services state and local governments buy to manage hydrogen sulfide odor, corrosion, and related hazards in wastewater collection and treatment systems. Recent solicitations under this code reveal that water and wastewater authorities purchase hydrogen peroxide, magnesium hydroxide slurry, sodium bisulfite solution, and related chemical reagents for lift stations, pump stations, force mains, and treatment plants; they also contract for the delivery and application services that deploy these chemicals in operational settings. Issuing bodies include municipal water and wastewater departments, water authorities, and city utilities divisions across multiple states. The work ranges from standalone chemical supply agreements (where vendors furnish raw materials under firm-fixed-price or requirements contracts) to integrated service contracts (where vendors apply chemicals on-site and manage dosing and monitoring). Scope often requires NSF/ANSI certification, rapid delivery (24 to 72 hours), hazmat transportation licensing, and adherence to specific technical specifications such as solids content, pH, viscosity, and particle size.

Geographic activity clusters in the Southeast and Southwest, with recent opportunities in Georgia (Cartersville Water Department, Macon Water Authority, City of Griffin, City of Tallahassee), Texas (City of Temple, City of Austin, Dallas Independent School District, City of Lubbock), and Florida (City of Orlando, City of Tallahassee). Representative recent solicitations include the City of Cartersville Water Department's request for bids on multiple treatment chemicals (aluminum sulfate solution, liquid lime slurry, chlorine, sodium hypochlorite, sodium bisulfite) due October 30, 2026 under an IFB; the City of Tallahassee's sealed-bid procurement for magnesium hydroxide slurry under IFB-067-26-CPW with a five-year initial term and optional two-year renewals, bids due June 16, 2026; the City of Austin's rebid for sodium bisulfite solution delivery to wastewater treatment plants under IFB 2200 BYS1051REBID, due June 9, 2026; and the City of Orlando's service contract solicitation for hydrogen peroxide and PRISC application at three lift stations, proposals due September 9, 2026. Local vendor preferences and SBE compliance requirements appear in several jurisdictions (Dallas ISD applies SBE scoring weight up to 20 percentage points; City of Temple and City of Austin apply local preference pricing; City of Tallahassee offers local-vendor preference points). Contract terms typically run one to five years with renewal options, and performance often requires advance security clearances and background checks at treatment facilities.
