UNSPSC 12164000: Bactericides

UNSPSC 12164000 Bactericides is a Class code that classifies chemical treatment products used to control microbiological growth, corrosion, and scale in water and wastewater infrastructure. State and local governments procure bactericides and related biocides alongside a broader suite of water-treatment chemicals—chlorine, polymers, coagulants, caustics, and oxidizers—most commonly as components of annual supply contracts or standing orders rather than as standalone purchases. Recent solicitations show bactericides and biocides appearing in integrated chemical suites for municipalities; standalone bactericide procurements are less common than combined commodity contracts.

State water and wastewater utilities drive the majority of recent activity under or near this code. Cities, regional water authorities, and county water-reclamation districts are the primary issuing bodies; school districts and special districts appear less frequently. A representative recent procurement is Collier County's October 2026 ITB for countywide chemicals (Solicitation 268705, response due November 13, 2026), which specifies 29 chemical line items for three water treatment facilities and two regional wastewater plants, with estimated annual historical spending of $4 million; the City of Waco has issued multiple separate ITBs throughout July and August 2026 for discrete chemical products (liquid chlorine, sodium hydroxide, aluminum sulfate, polyaluminum chloride, polymers, and oxygen) for water and wastewater treatment. Geographic activity concentrates in Florida, Georgia, and Texas, with secondary activity in Oregon, Connecticut, and Arizona. Recent opportunities are primarily ITBs and RFPs with response windows of two to six weeks; most municipal utilities require NSF 60/61 certification, AWWA compliance, and firm pricing for 12-month terms. Issuers increasingly specify local-vendor preferences where ordinance permits and often require pre-approval of alternate formulations or samples prior to bid submission.
