UNSPSC 12352304: Inorganic peroxides

UNSPSC 12352304 Inorganic peroxides (Commodity) covers chemical compounds that state and local governments procure primarily for wastewater treatment, water quality management, and infrastructure maintenance—specifically calcium chloride and magnesium hydroxide slurry for municipal operations. The issuing bodies are city and county departments of public works and water resources, plus special-purpose water authorities. The City of Detroit Office of Contracting and Procurement, Gwinnett County Board of Commissioners, the City of Tallahassee, and the Brazos River Authority represent the jurisdictions now actively soliciting under this code. The work is highly specialized: calcium chloride in liquid form for de-icing city streets; magnesium hydroxide slurry for hydrogen sulfide control, odor suppression, and corrosion mitigation in wastewater collection systems; and solids dewatering polymer for sludge treatment at water reclamation facilities. Vendors must typically demonstrate three to five years of relevant supply experience, maintain appropriate insurance coverage (general liability ranging from $1 million to $2 million), and comply with state environmental and municipal licensing requirements. Most contracts are term agreements of two to five years with optional renewal periods, priced on a per-gallon or per-ton basis with firm pricing for initial contract years.

Recent solicitation activity concentrates in the Southeast and Midwest. Detroit posted an RFQ on September 30, 2026 for 200,000 gallons of liquid calcium chloride for ice control with quotes due October 14, 2026, requiring vendor facilities within 20 miles of the city and 24/7 accessibility. Tallahassee issued an IFB on May 1, 2026 for magnesium hydroxide slurry on a firm-fixed-price requirements contract spanning five years with two optional two-year renewals, bids due June 16, 2026, with local vendor preference available for Leon County area businesses. Gwinnett County solicited solids dewatering and thickening polymer on July 1, 2026 for three water reclamation sites, bids due July 30, 2026, with a four-year initial term plus optional one-year renewals and mandatory performance testing for all products except the pre-approved Polydyne Clarifloc SE-1748. All three opportunities enforce lowest-responsive-bidder award criteria and require detailed product certification, including certificates of analysis and third-party laboratory testing results.
