UNSPSC 12163800: Chemical scavengers

UNSPSC 12163800 Chemical scavengers is a Class code under which state and local governments procure specialized treatment chemicals—primarily hydrogen peroxide, magnesium hydroxide, sodium bisulfite, and related oxidizing or precipitating agents—for water and wastewater treatment systems to control hydrogen sulfide, corrosion, odor, and residual chlorine in municipal water supplies and sewage collection systems. Water departments and independent school districts are the dominant issuing bodies, with municipal utilities procuring these products on regular supply contracts tied to treatment-plant operations; specialized applications include corrosion control at pump stations and lift stations where hydrogen sulfide buildup poses operational and maintenance risks. Recent solicitations show municipalities purchasing these chemicals as NSF Standard 60–approved line items under annual supply agreements with firm pricing and multiple-vendor delivery capability to ensure supply continuity.

Activity is concentrated in the Southeast and Texas, with recent opportunities from Georgia, Florida, Texas, and Connecticut demonstrating consistent baseline demand. The City of Cartersville Water Department issued an IFB (PE60899NONST2027000000086, due October 30, 2026) for aluminum sulfate solution, liquid lime slurry, chlorine, hydrofluosilicic acid, sodium hypochlorite, and sodium bisulfite across two treatment facilities on a line-item award basis; the Macon Water Authority and City of Griffin issued similar sealed-bid solicitations for water and wastewater chemicals in Georgia (August and May 2026 respectively). The City of Tallahassee released a competitive five-year requirements contract (IFB-067-26-CPW, due June 16, 2026) for magnesium hydroxide slurry with rigorous product specifications, a minimum five-year supplier-experience requirement, and local vendor preference eligibility for businesses operating in Leon, Wakulla, Gadsden, or Jefferson County. Dallas Independent School District posted an RFP (JKJ250402, due October 15, 2026) for district-wide water treatment services with SBE participation weighted at up to 20 evaluation points and a 30 percent SBE aspirational participation goal. The City of Austin's IFB (2200 BYS1051REBID, due June 9, 2026) for sodium bisulfite delivery to wastewater treatment plants included a 5 percent local-business evaluation discount and required NSF approval and three municipal references. Most contracts run one to three years with renewal options; delivery windows are typically 48 to 72 hours, and all chemicals must meet NSF/ANSI standards and federal water-quality certification requirements.
