UNSPSC 12164102: Acid additives

UNSPSC 12164102 Acid additives (Commodity) covers water treatment chemicals purchased by municipal water departments and county utilities for disinfection, pH control, and coagulation—including muriatic acid, hydrochloric acid, and sulfuric acid derivatives used in potable water systems, wastewater treatment, and pool operations. Recent state and local solicitations show municipalities and special districts procuring these acids as line items within broader water treatment chemical packages or standalone supplies, often bundled with caustic soda, aluminum sulfate, sodium hypochlorite, and other treatment compounds. Issuing bodies include city water departments, county utilities, school districts operating pools, and county landfill facilities. The City of Meriden, the City of Griffin, and Sarasota County are among recent repeat buyers; water reclamation and landfill operations also drive consistent demand.

Solicitations are concentrated in the Southeast and Mid-Atlantic: Florida, Georgia, Connecticut, Ohio, and Texas show the most recent activity. Representative opportunities include the City of Meriden's ITB B026-55 (due June 25, 2026) for water treatment chemicals including calcium hypochlorite and liquid aluminum sulfate with NSF and AWWA certification requirements; Sarasota County's Quick Quote 2026QQ704 (due May 12, 2026) for twelve 55-gallon drums of industrial-grade muriatic acid (HCl 31.5%) for membrane cleaning at the Bee Ridge Water Reclamation Facility; the Hillsborough County ITB 26-00158 (due March 4, 2026) for technical-grade hydrochloric acid at 31.5–33.1% concentration for landfill leachate treatment over three years, estimated at $412,957.50; and the City of Jackson Water Treatment Plant's competitive solicitation (due May 27, 2026) for NSF-certified water treatment chemicals for fiscal year 2026–27. Build America Buy America Act compliance, NSF/ANSI Standard 60 certification, and AWWA standards are standard requirements; contracts typically run one year with renewal options and award on lowest responsive bidder basis, with firm pricing for the initial term and CPI-indexed adjustments thereafter.
