UNSPSC 12352316: Sodium hydroxide

A chemical compound known as NaOH

UNSPSC 12352316 Sodium hydroxide (Commodity) covers purchase and supply of sodium hydroxide and closely related chemical disinfectants used in municipal water treatment, wastewater operations, and facility maintenance. Recent state and local solicitations show water pollution control authorities and county governments buying sodium hydroxide membrane grade 25% as a reagent for pH adjustment and chemical treatment in drinking and wastewater systems, while some jurisdictions are procuring hypochlorous acid generators that produce disinfectant on demand using sodium hydroxide as a precursor. The issuing bodies are primarily municipal water authorities (Stamford, Connecticut Water Pollution Control Authority), municipal utilities (City of Flowery Branch), and county facilities management (Escambia County Board of County Commissioners). No standout repeat buyers appear in the recent record beyond Stamford's WPCA, which issued two separate ITBs for sodium hydroxide membrane grade 25% within a two-month window.

Geographic activity clusters in the Southeast and Northeast.
