UNSPSC 12352309: Silica

Silica is pure sand and inorganic in nature with apllications like in ceramics, glass, abrasives, etc.

UNSPSC 12352309 Silica, a Commodity code, covers chemical products and additives used in municipal infrastructure, wastewater treatment, and public works operations — but the recent solicitations tagged under this code show minimal alignment with silica itself. State and local governments are actually procuring calcium chloride for ice control, magnesium hydroxide slurry for wastewater odor and corrosion control, dewatering and thickening polymers for sludge processing, herbicides and fertilizers for grounds maintenance, and sealant compounds. The issuing bodies are predominantly utilities, water authorities, and public works departments: the City of Detroit Office of Contracting and Procurement, Gwinnett County Board of Commissioners (Department of Water Resources), the Brazos River Authority, the City of Tallahassee, and Pasco County. The code appears to function as a catch-all or misfiled category for chemical supply and treatment products across water, wastewater, and public works procurements rather than a code with consistent scope.

Recent activity concentrates in Florida, Georgia, Michigan, and Texas. Representative solicitations include the City of Detroit's RFQ for 200,000 to 100,000 gallons of liquid calcium chloride for street ice control (due October 14, 2026), with Detroit-based vendors eligible for pricing credits of 1–5%; the Gwinnett County competitive sealed-bid procurement for solids dewatering and thickening polymer on a four-year annual contract for water reclamation facilities (bids due July 30, 2026); and the City of Tallahassee's Invitation for Bid for magnesium hydroxide slurry supply on a five-year firm-fixed-price requirements contract with optional two-year renewals (bids due June 16, 2026, with award anticipated by August 2026). Dallas County posted two sparse solicitations for sealant compound and brake-parts cleaner with minimal documentation. The mismatch between the code name and actual procurement scope suggests that vendors should verify code assignments before pursuing opportunities or rely on direct opportunity feeds rather than code-level filtering.
