UNSPSC 12352400: Mixtures

UNSPSC 12352400 Mixtures, a Class code, encompasses water treatment and wastewater process chemicals that state and local governments procure on regular, often annual, supply contracts. Recent solicitations show municipalities purchasing sodium hypochlorite, chlorine gas, ferric chloride, aluminum sulfate, sodium bisulfite, magnesium hydroxide, potassium permanganate, hydrochloric acid, ammonium sulfate, hydrofluorosilicic acid, and ancillary treatment aids—typically in bulk or drum quantities, delivered on as-needed or regularly scheduled bases to water treatment plants and wastewater reclamation facilities. All products across these solicitations are required to meet NSF Standard 60 or equivalent AWWA certification. Issuing bodies span cities (Santa Cruz, Edinburg, Cocoa, Tallahassee, Temple, Griffin, Dublin, Milledgeville, St. Petersburg), counties (Indian River County, San Bernardino County, Clackamas County), the Solid Waste Authority of Palm Beach County, a school district (Clayton County Public Schools), and special-purpose districts (Clackamas County Water Environment Services). Cities appear as repeat purchasers, with most jurisdictions soliciting annually or on rolling requirements-contract terms. Pricing is typically quoted on a per-unit (gallon, pound, dry ton, or cylinder) delivered basis with firm pricing for the initial contract year, and product quality is verified through certificates of analysis, material safety data sheets, and NSF certifications as mandatory submittals.

Geographic activity concentrates in Florida (Cocoa, St. Petersburg, Tallahassee, Indian River County, Palm Beach County) and Georgia (Milledgeville, Griffin, Clayton County), with additional solicitations posted from Texas (Edinburg, Temple), Arizona (Tolleson), Connecticut (Manchester, Meriden), California (Santa Cruz, Milpitas), Oregon (Clackamas County), and Pennsylvania (implied through San Bernardino sourcing). Representative recent opportunities include the City of Edinburg, Texas issuing ITB 2027-06 for an annual 12-month water plant chemical supply (chlorine, aluminum sulfate, sodium chlorite, filter polymers) due September 29, 2026; the City of Cocoa, Florida posting ITB B2617COC for liquid sodium hypochlorite delivered on 72-hour notice at 5% local preference for Brevard County contractors, due September 23, 2026; the City of St. Petersburg, Florida soliciting IFB-26-312 for ferric chloride delivered as-needed to a reclamation facility at approximately 108,800 gallons annually, proposals due September 15, 2026; and the Town of Manchester, Connecticut issuing ITB 25/26-59 for eleven water treatment chemicals including hydrated lime, sodium hypochlorite, PACI coagulant, and zinc orthophosphate, due May 22, 2026. Contract terms typically run one year with renewal options, and most solicitations employ competitive sealed-bid or IFB processes with electronic submission portals. Insurance, bonding, experience verification, and compliance with state water quality standards are standard qualifications.
