UNSPSC 47101604: Boiler feed chemicals

UNSPSC 47101604 Boiler feed chemicals, a Commodity code, encompasses treatment additives and chemical compounds that state and local governments purchase to maintain boiler and steam generation systems — including corrosion inhibitors, oxygen scavengers, alkalinity builders, and scale preventatives. Recent solicitations show demand spanning water treatment in school districts, municipal utility systems, public housing authorities, and wastewater treatment facilities. State and local buyers procure these chemicals both as standalone supply contracts and as components of larger maintenance or operational programs. Dallas Independent School District issued RFP JKJ250402 in September 2026 for district-wide water treatment services on an as-needed basis with a three-year term and up to two one-year renewals, carrying an SBE participation requirement with up to 20 percentage points of evaluation weight. The City of Phoenix Housing Department posted IFB FY27-086-03 in August 2026 for chiller and boiler system maintenance at multiple city-owned housing properties, specifying monthly chemical testing of hardness, alkalinity, chlorides, nitrite, phosphates, pH, conductivity, and biological activity, with a five-year fixed term. The City of Tallahassee solicited proposals in July 2026 for power plant chemical treatment programs at the A. B. Hopkins and Sam O. Purdom Generating Stations, covering boiler and heat-recovery steam generator treatment chemicals and consultation services.

Geographic activity clusters in the Southeast and Midwest. Connecticut municipalities—particularly the Town of Killingly—represent the most concentrated recent buyer segment, with multiple June 2026 solicitations for water and wastewater treatment chemicals including polymer emulsion, polyaluminum chloride, sodium bisulfite, and silicon dioxide defoamer, all with July 13, 2026 proposal deadlines. The City of Meriden, Connecticut posted ITB B026-55 in June 2026 for chemicals including calcium hypochlorite, liquid caustic soda, and liquid aluminum sulfate under Build America Buy America sourcing restrictions. Georgia cities including LaGrange and Griffin issued sealed bids in May and April 2026 for water treatment chemicals on line-item bases with firm pricing for 12 months and delivery windows of 24 to 72 hours. Pennsylvania and Wisconsin housing authorities—Harrisburg Housing Authority and City of Madison Community Development Authority—posted bids for boiler replacement and steam supply line repairs in June and July 2026, both subject to Davis-Bacon prevailing-wage requirements. The City of Atlanta conducted prequalification for trace organic laboratory testing services in May 2026 to support wastewater compliance and industrial pretreatment monitoring. Set-asides vary by issuing body; SBE participation goals appear in school district and some city procurements, while Davis-Bacon and HUD Section 3 compliance apply to housing authority and federally funded projects.
