UNSPSC 12160000: Additives

UNSPSC 12160000 Additives (Family) encompasses treatment chemicals, reagents, and specialty compounds that state and local governments procure for water treatment, wastewater management, and laboratory analysis operations. Recent solicitations show municipalities and utilities buying sodium hypochlorite, sodium hydroxide, potassium permanganate, calcium chloride, liquid calcium nitrate, and refrigerated liquid carbon dioxide for drinking water production, wastewater odor control, hydrogen sulfide removal, and dust suppression. The mix of issuing bodies is heavily weighted toward municipal water and wastewater utilities and municipal departments, with several Connecticut towns (Groton, Meriden, Norwich) and Pennsylvania municipal authorities (Morrisville) issuing multiple ITBs and RFQs for chemical supply contracts in the past four months. A university procurement (University of Connecticut, University of Texas System) and one city environmental agency (Tucson) also appear in recent activity, though the University of Texas opportunity centers on oligonucleotide products and reagents for research rather than municipal operations.

Connecticut and Pennsylvania dominate the geographic spread, with the Town of Groton alone posting four separate ITBs for water treatment and maintenance chemicals (sodium hypochlorite, sodium hydroxide, potassium permanganate, liquid calcium nitrate) and agricultural additives—all due May 1, 2026. Arizona (Tempe), Florida (Santa Monica), and Massachusetts (Worcester) show sporadic activity. Representative recent opportunities include the City of Santa Monica Water Resources Division IFB 12602079 (due June 9, 2026) for EPA-approved laboratory services performing microbial source tracking PCR assays on water samples, the Town of Groton ITB 26-14 (due May 1, 2026) for approximately 20,000 to 30,000 gallons of 15% sodium hypochlorite solution annually, the City of Tempe RFP (due March 5, 2026) for refrigerated liquid carbon dioxide at 99.5% purity with approximately 1,160 tons annual requirement, and the Municipal Authority of Morrisville sealed bid (due June 4, 2026) for sodium bisulfite, sodium hypochlorite, and hydrated lime via PennBid. Most municipal procurements apply local vendor preferences allowing bidders within 5% of the lowest price to match and receive award consideration, require tax-exempt status compliance, and mandate general liability insurance of $1,000,000 to $2,000,000 per occurrence.
