UNSPSC 12163901: Scale inhibitor

UNSPSC 12163901 Scale inhibitor is a Commodity code under which state and local governments procure chemical treatment products and services for water and wastewater system operations. Recent solicitations show that municipalities and water authorities are buying scale inhibitors and related treatment chemicals—including hydrogen peroxide, sodium bisulfite, magnesium hydroxide, and various coagulants and disinfectants—for corrosion control, odor management, hydrogen sulfide suppression, and general water quality treatment across drinking water plants and wastewater collection and treatment systems. Issuing bodies include city water departments and utilities (Cartersville Water Department, City of Austin, City of Tallahassee), independent school districts (Dallas Independent School District), county water authorities (Macon Water Authority, Gwinnett County), and standalone engineering or service contracts for land application consulting. The scope ranges from individual chemical supply contracts awarded line-item-by-line-item to larger service agreements for chemical application, delivery, and system monitoring.

Geographic activity clusters in Texas and Georgia, with recent solicitations also posted in Florida, Connecticut, and Arizona. Representative recent opportunities include the City of Cartersville Water Department's IFB for water treatment chemicals due October 30, 2026, soliciting aluminum sulfate solution, liquid lime slurry, chlorine, and hydrofluosilicic acid for two treatment plants with annual deliveries spanning 3 to 75 loads depending on chemical; the City of Austin's IFB 2200 BYS1051REBID for sodium bisulfite delivery due June 9, 2026, on an as-needed basis to wastewater treatment plants with a 5% local-business evaluation discount; the City of Tallahassee's five-year firm-fixed-price IFB for magnesium hydroxide slurry supply due June 16, 2026, serving 1,000 miles of sewer main and 114+ pump stations with rigorous product specifications, NSF Standard 60 certification, and local vendor preference; and the City of Temple, Texas's ITB for 875,000 wet pounds of liquid ammonium sulfate annually due June 10, 2026, with a 5% local-preference adjustment for vendors based within Temple city limits.
