UNSPSC 12352302: Inorganic metal salts

UNSPSC 12352302 Inorganic metal salts (Commodity) covers chemical compounds that state and local governments purchase for water treatment, wastewater management, ice control, and facility maintenance. Recent solicitations show procurement officers buying calcium chloride for de-icing applications, magnesium hydroxide slurry for corrosion and odor control in wastewater systems, and solids dewatering polymers for sludge treatment. The issuing bodies are primarily municipal public works and water-resource departments, county boards of commissioners, and regional water authorities. The City of Detroit, Gwinnett County (Georgia), the City of Tallahassee, and the Brazos River Authority appear as active recent buyers. Specifications tend to be precise—vendors must meet exact pH, solids composition, particle-size, viscosity, and density requirements with third-party laboratory certification. Bidders routinely face minimum experience thresholds (three to five years), insurance requirements (general liability typically $1 million to $2 million, workers' compensation at statutory minimums), and F.O.B. Destination pricing that embeds all labor, transportation, and equipment costs into per-unit rates.

Recent activity concentrates in the Southeast and Midwest, with the City of Detroit (RFQ 551467, calcium chloride, quotes due October 14, 2026), Gwinnett County (IFB PE77023NONST2027000000655, solids dewatering polymer, bids due July 30, 2026), the City of Tallahassee (IFB-067-26-CPW, magnesium hydroxide slurry, bids due June 16, 2026), and the Brazos River Authority near Houston (ITB 261394, sludge hauling and liquid waste disposal, bids due August 20, 2026). The Detroit RFQ offers a near-term opportunity for liquid calcium chloride suppliers within 20 miles of the city, with an estimated 300,000 gallons needed under a two-year contract; Detroit's equalization credit policy creates pricing leverage for qualified local or Detroit-resident vendors. Contract terms are typically one to five years with optional renewal periods, and awards go to the lowest responsive and responsible bidder meeting all specifications and insurance requirements.
