UNSPSC 12352310: Silicones

Silicones are siloxane polymers based on silicons and oxygen used for adhesives, sealants etc

UNSPSC 12352310 Silicones is a Commodity code that encompasses industrial chemical products including brake-parts cleaners, polymer treatment agents for wastewater and drinking water processing, de-icing compounds, greases, epoxies, oils, and magnesium hydroxide slurry for hydrogen sulfide and odor control in municipal infrastructure. State and local buyers under this code range from transit authorities to county water resources departments to city wastewater systems and municipal maintenance operations, with Dallas Area Rapid Transit Authority (DART) appearing as a frequent buyer of maintenance supplies and lubricants across multiple purchase orders. The work being solicited reflects operational needs for vehicle and equipment maintenance, water treatment chemical supply, and infrastructure corrosion control rather than manufacturing or research applications.

Recent activity spans Texas (Dallas County, Gwinnett County in Georgia), and Florida (Pasco County and Leon County). Representative recent solicitations include DART's purchase of brake-parts cleaner in 14 oz containers (Solicitation 2099612, response due July 7, 2026, as an IFB or purchase order), Gwinnett County Board of Commissioners' competitive sealed bid for solids dewatering and thickening polymer on an annual contract for wastewater treatment (Solicitation PE77023NONST2027000000655, bids due July 30, 2026), City of Tallahassee's sealed bid for magnesium hydroxide slurry supply for hydrogen sulfide and corrosion control in its sewer system (Solicitation IFB06726CPW, bids due June 16, 2026), and Pasco County's invitation for bid for herbicides, fertilizers, and pesticides on an as-needed basis (Solicitation IFBSP26074, bids due June 16, 2026). DART maintains a steady pipeline of small-commodity purchase orders with four-to-seven-day response windows; other jurisdictions typically allow fifteen to thirty days for bid preparation. Most recent opportunities are competitively bid with FOB Destination terms and Net 30 payment, with no standout set-asides or local-preference programs noted except Pasco County's local-vendor-preference option and Tallahassee's local-vendor affidavit pathway.
