UNSPSC 12352303: Inorganic oxides

UNSPSC 12352303 Inorganic oxides, a Commodity code, covers chemical compounds state and local governments procure for water treatment, wastewater management, ice control, and environmental remediation. Recent solicitations show demand for liquid calcium chloride for street de-icing, magnesium hydroxide slurry for sludge dewatering and hydrogen sulfide control in wastewater systems, solids dewatering polymers, and herbicides and fertilizers for maintenance operations. Issuing bodies include city public works departments, county boards of commissioners, regional water authorities, and county maintenance operations. The Detroit RFQ for 300,000 gallons of liquid calcium chloride illustrates the scale and specification rigor typical under this code—vendors must meet precise pH and solids composition ranges, demonstrate three years of relevant experience, maintain 24/7 facility access within a defined radius, and carry $1 million liability insurance. The Gwinnett County polymer procurement and Tallahassee magnesium hydroxide solicitation reflect multi-year framework contracts with performance testing requirements, firm pricing for initial terms, and capped annual adjustments thereafter.

Recent activity clusters in the Southeast and Midwest. The City of Detroit, Gwinnett County Board of Commissioners (Georgia), the City of Tallahassee (Florida), Pasco County (Florida), and the Brazos River Authority (Texas) posted solicitations between May and October 2026. The Detroit calcium chloride RFQ closed October 14, 2026 with local vendor equalization credits up to 5%; the Tallahassee magnesium hydroxide IFB closed June 16, 2026 with local vendor preference for Leon, Wakulla, Gadsden, or Jefferson County businesses; and the Gwinnett County polymer procurement closed July 30, 2026, requiring mandatory bench-scale and full-scale performance testing by July 22. Dallas County posted two minimally detailed commodity solicitations in June and July 2026 with short lead times, consistent with blanket-order or cooperative purchasing mechanics. Most solicitations award to the lowest responsive and responsible bidder on a per-unit basis (gallon, ton, or dry ton) with NET 30 or monthly invoice payment terms.
