UNSPSC 12352402: Inorganic chemical mixtures

UNSPSC 12352402 Inorganic chemical mixtures (Commodity) covers chemical additives and compounds used by state and local jurisdictions in wastewater treatment, water quality management, and highway maintenance. State and local buyers under this code procure liquid calcium chloride for de-icing, magnesium hydroxide slurry for hydrogen sulfide and corrosion control in sewer systems, solids dewatering and thickening polymers for wastewater processing, and herbicides, fertilizers, and pesticides for grounds maintenance. Recent solicitations show city public works departments, county water authorities, wastewater treatment operators, and regional utilities as primary issuing bodies. The City of Detroit, Gwinnett County Board of Commissioners, City of Tallahassee, Brazos River Authority, and Pasco County have posted competitive sealed bids and RFQs under this code within the past four months, typically requiring minimum three to five years of vendor experience, specialized product certifications (including ANSI/NSF Standard 60 for water-contact chemicals), liability insurance minimums ranging from $1 million to $2 million, and firm-fixed pricing on per-gallon or per-ton bases over multi-year initial terms with renewal options.

Recent activity concentrates in Florida, Georgia, and Michigan, with secondary postings in Texas. The City of Detroit Office of Contracting and Procurement issued an RFQ for 200,000 to 100,000 gallons of liquid calcium chloride (specifications: 57–62% calcium chloride by weight, pH 5) due October 14, 2026, with vendor facilities required within 20 miles of Detroit city limits and available 24/7, a two-year term with renewal options, and a local Detroit-vendor preference credit of 1–5%.
