UNSPSC 12352306: Inorganic hydrides

UNSPSC 12352306 Inorganic hydrides (Commodity) encompasses chemical products state and local governments procure for water treatment, wastewater management, and infrastructure maintenance—specifically liquid and slurry chemical compounds used for sludge handling, corrosion control, odor suppression, and ice management. Recent state and local solicitations show water authorities, city public works departments, and county governments sourcing calcium chloride for de-icing, magnesium hydroxide slurry for hydrogen sulfide and corrosion control in wastewater systems, and solids dewatering polymers for treatment facilities. The work involves firm-fixed-price supply contracts with specified chemical composition, purity, and performance standards; vendors typically must demonstrate three to five years of relevant experience, maintain specialized insurance (general liability $1 million to $2 million, workers' compensation at statutory limits), provide product certifications and third-party laboratory testing, and deliver on F.O.B. Destination terms with all labor and transportation embedded in unit pricing. Multi-year terms with renewal options are standard, and pricing often includes CPI-U adjustment provisions or capped annual increases.

Activity spans multiple regions with recent opportunities posted by the City of Detroit, Gwinnett County (Georgia), the City of Tallahassee (Florida), and the Brazos River Authority (Texas). The City of Detroit Office of Contracting and Procurement posted an RFQ on September 30, 2026 (quotes due October 14, 2026) for 200,000 gallons of liquid calcium chloride at vendor-site loading plus 100,000 gallons for tank delivery, requiring 57–62% calcium chloride concentration, three years of experience, and a facility within 20 miles of Detroit; the contract includes a local-vendor equalization credit of 1–5% for Detroit-based businesses. The Gwinnett County Board of Commissioners issued a competitive sealed-bid solicitation on July 1, 2026 (bids due July 30, 2026) for solids dewatering and thickening polymer on a four-year annual contract beginning October 19, 2026, with mandatory bench-scale and full-scale performance testing required by July 22, 2026. The City of Tallahassee posted IFB-067-26-CPW on May 1, 2026 (bids due June 16, 2026) for Magnesium Hydroxide slurry on a five-year firm-fixed-price requirements contract with optional two-year renewals, requiring five years of prior wastewater-system experience and strict chemical-composition specifications including 8.0–7.0 lb/gal Magnesium Hydroxide content and ANSI/NSF Standard 60 certification. All three jurisdictions applied local-vendor preferences or eligibility restrictions and required sealed-bid or RFQ response within one to two weeks of posting.
