UNSPSC 47101602: Antiscalants

UNSPSC 47101602 Antiscalants, a Commodity code, describes chemical treatment products for industrial water systems, though state and local procurement activity under this code focuses primarily on water and wastewater treatment chemicals for municipal facilities rather than antiscalant products narrowly defined. Recent solicitations show jurisdictions buying degreasing compounds for wet wells, sodium hypochlorite for disinfection, sodium bisulfite for dechlorination, liquid aluminum sulfate for coagulation, ferric chloride for phosphorus removal, caustic soda for pH adjustment, and cationic polymers for solids dewatering—the full spectrum of potable and treatment-plant chemistry. Issuing bodies span city water departments (Cocoa, DeLand, Dublin, LaGrange, Milledgeville, Valdosta, Waco), county sewer districts (Rockland County Sewer District #1, Pike County Water & Sewerage Authority), county water authorities (Cobb County-Marietta Water Authority, Macon Water Authority), special water districts (Clean Water Services in Oregon, Santa Cruz Water Department), and school districts and industrial/commercial facilities. The mix reflects reliance on competitive procurement for recurring commodity supply. Collier County, Gwinnett County, and the City of Waco are visible as repeat buyers with multiple recent line-item solicitations.

Activity concentrates in Florida (Collier County, Cocoa, DeLand, Rockland County, Palm Beach County), Georgia (Cobb County-Marietta, Cartersville, Dublin, Gwinnett County, LaGrange, Milledgeville, Valdosta), and Texas (Dallas, Waco), with scattered municipal activity in Oregon, Connecticut, and California. Representative solicitations include Collier County ITB 268705 for 29 chemical line items across three water and two wastewater plants, posted October 13, 2026, with bids due November 13; City of Waco's suite of eight RFBs issued July 30, 2026 for liquid chlorine, sodium hydroxide, aluminum sulfate, polyaluminum chloride, ammonium sulfate, liquid oxygen, polymers, and sulfur dioxide, all due August 20–21; and City of DeLand ITB B-26-18 for polymer and liquid chemicals for wastewater treatment facilities, posted September 28 with bids due September 15. Contract terms typically run one to four years with annual or option-period renewals, pricing held firm for the initial term, and delivery required within two to five business days of order. Most solicitations require NSF 60 certification and AWWA compliance, pre-approved product lists, and technical support at no extra charge.
