UNSPSC 12163801: Hydrogen sulfide scavengers

UNSPSC 12163801 Hydrogen sulfide scavengers is a Commodity code covering chemical products used by municipal water and wastewater systems to control hydrogen sulfide-related corrosion, odor, and sulfide precipitation in collection systems and treatment plants. State and local governments buy hydrogen peroxide, magnesium hydroxide slurry, sodium bisulfite, and related chemical formulations for direct injection into lift stations, pump stations, force mains, and treatment facilities serving populations ranging from tens of thousands to hundreds of thousands. The code sees activity from municipal water departments, city public utilities, regional water authorities, and independent school districts, with water departments appearing as the dominant buyer class. These jurisdictions operate on annual supply contracts structured with firm-fixed unit pricing, multiline chemical procurement bundles, and renewal option provisions extending two to five years.

Activity concentrates in the South and Southwest, with recent solicitations from Cartersville and Macon in Georgia, Gwinnett County in Georgia, Tallahassee in Florida, Orlando in Florida, Austin and Temple in Texas, and Lubbock in Texas, alongside procurement by the City of Meriden in Connecticut and Dallas Independent School District. Representative opportunities include the City of Cartersville Water Department (IFB PE60899NONST2027000000086, bids due October 30, 2026) seeking sodium bisulfite and other treatment chemicals for two plants; the City of Orlando (IFB260556, proposals due September 9, 2026) for hydrogen sulfide control service via hydrogen peroxide and PRISC application at three lift stations; the City of Tallahassee (IFB IFB06726CPW, bids due June 16, 2026) for magnesium hydroxide slurry delivery under a five-year contract with two optional two-year renewals for hydrogen sulfide and odor control across approximately 1,000 miles of sewer main and 114 pump stations; and the City of Austin (IFB 2200 BYS1051REBID, bids due June 9, 2026) for sodium bisulfite solution in 330-gallon totes on an as-needed basis to wastewater treatment plants. Dallas Independent School District (RFP JKJ250402, proposals due October 15, 2026) solicits district-wide water treatment services under a three-year base term with two optional one-year renewals, with SBE participation carrying evaluation weight of up to 20 percentage points.
