UNSPSC 12352319: Calcium hydroxide

UNSPSC 12352319 Calcium hydroxide is a Commodity code that, based on recent state and local solicitations, encompasses chemical products and related services for environmental management, facility maintenance, and waste treatment rather than the narrow scope its name suggests. State and local governments are procuring these materials and associated services through a mix of issuing bodies: cities (Philadelphia), counties (Escambia County), and special-purpose districts (Brazos River Authority). The actual buying spans herbicides and disinfectant generation systems for facility management, sludge hauling and liquid waste disposal services tied to wastewater treatment operations, and related chemical handling and maintenance support. Issuing bodies vary from municipal procurement departments managing routine facility supply contracts to regional authorities managing multi-plant infrastructure operations.

Recent opportunities show activity in Texas and Florida. The City of Philadelphia Procurement Department posted a micro order purchase RFQ (Solicitation B2728201) due October 14, 2026, for herbicide delivery across six districts with a maximum contract value of $45,000 and a 365-day requirements contract term. Escambia County Board of County Commissioners solicited proposals (PD2526083) due August 11, 2026, for purchase, installation, and maintenance of a hypochlorous acid generator capable of on-demand disinfectant production across all county facilities, with cybersecurity compliance requirements outlined in supplementary technical documents. The Brazos River Authority issued a sealed-bid IFB (261394) due August 20, 2026, for sludge hauling and liquid waste disposal services across four Sugar Land Wastewater Treatment Plants, covering an estimated 15,040 tons of annual sludge with self-performance requirements and a potential five-year initial-plus-renewal term structure.
