UNSPSC 12163801: Hydrogen sulfide scavengers

UNSPSC 12163801 Hydrogen sulfide scavengers is a Commodity code. State and local water and wastewater treatment authorities are actively procuring chemical products tagged to this code, though the recent solicitations show a mix of direct hydrogen sulfide control agents and broader water treatment chemicals. The City of Tallahassee's magnesium hydroxide slurry contract (IFB-067-26-CPW, due June 16, 2026) explicitly names hydrogen sulfide control, odor control, and corrosion control as core applications across a 1,000-mile sewer system serving 165,000 people. The City of Austin's sodium bisulfite contracts (IFB 2200 BYS1051 and its rebid IFB 2200 BYS1051REBID, due March 12 and June 9, 2026) serve redundant backup chlorine reduction in wastewater discharge. However, concurrent solicitations from Meriden, Connecticut (ITB B026-55, due June 25, 2026), Temple, Texas (BID510227, due June 10, 2026), Griffin, Georgia (Bid #26-008, due May 28, 2026), and Flowery Branch, Georgia (26-007, due April 21, 2026) address broader potable and wastewater chemistry—sodium hypochlorite, caustic soda, aluminum sulfate, liquid ammonium sulfate, and polymers—without explicit hydrogen sulfide scavenging language. Issuers include city water departments, county utilities divisions, and municipal wastewater authorities across mixed-size jurisdictions.

Recent activity concentrates in Texas (Austin, Temple, Lubbock), Florida (Tallahassee, Volusia County, Hillsborough County, Phoenix), Georgia (Griffin, Flowery Branch, Gwinnett County), and Connecticut (Meriden). The City of Tallahassee's five-year magnesium hydroxide supply contract (bids due June 16, 2026, award anticipated by August 2026) represents the most directly on-code procurement, requiring NSF Standard 60 certification, five years' supplier experience, and strict delivery (three calendar days normal, 24 hours emergency) to distributed tank locations. The City of Austin's sodium bisulfite ITB rebid (due June 9, 2026) covers 38% solution in 330-gallon totes to wastewater treatment plants with emergency 24-hour delivery and municipal reference requirements. The Volusia County corrosion inhibitor ITB (ITB #26-B-60LS, due April 13, 2026) procures NSF-certified ortho/polyphosphate inhibitor across six treatment facilities, blending hydrogen sulfide and corrosion control objectives. Most recent solicitations involve multi-year terms (three to five years), firm pricing for year one, and requirements for NSF/ANSI Standard 60 certification and municipal water utility references. Set-asides and preference programs vary by jurisdiction—Tallahassee offers local vendor preference, Austin allows optional local business and small-business certifications, and Texas municipalities apply statutory local preference discounts. Contract volumes suggest recurring annual demand, though specific dollar values appear only in equipment or sole-source procurements outside this code's direct scope.
