NIGP 88589: Stabilizers (Cyanuric Acid, etc.)

NIGP 88589 Stabilizers (Cyanuric Acid, Etc.), an Item code, covers the procurement of chemical stabilizers and related water-treatment compounds that state and local governments use to manage pH, chlorine residual, and water quality in municipal water systems and swimming pools. Recent solicitations show state and local buyers acquiring cyanuric acid granular alongside complementary treatment chemicals such as calcium hypochlorite, sodium hypochlorite, muriatic acid, sodium bicarbonate, and diatomaceous earth—often bundled with other coagulants, disinfectants, and pH adjusters in single RFQ or ITB notices. Issuing bodies include city water utilities, county school districts, and county environmental or public-works departments; all three solicitation sources (City of Griffin, Georgia; Pinellas County School District, Florida; and Hillsborough County Board of County Commissioners, Florida) appear in the recent-opportunities block.

Geographic activity concentrates in Florida and Georgia, with all four posted opportunities from these two states. The City of Griffin, Georgia issued ITB #26-008 for FY27 water treatment chemicals, posted April 29, 2026, with response due May 28, 2026, seeking line-item bids on sixteen chemicals including stabilizers and associated compounds for delivery to six treatment facilities. Pinellas County School District, Florida solicited RFQ #25-AM-018 for swimming pool chemicals posted February 26, 2026 (response deadline February 11, 2026, though that date appears to be an error in the source), requesting cyanuric acid granular and nine other pool chemicals for five school locations under an estimated $35,000 annual contract with potential two-year renewal. Hillsborough County Board of County Commissioners, Florida issued ITB 26-00158 for technical-grade hydrochloric acid posted February 13, 2026, with response due March 4, 2026, valued at $412,957.50 over three years—a larger-scale procurement serving a landfill leachate evaporator. Prices in the school-district and utility solicitations must meet AWWA and NSF 60 standards; delivery windows are tight, with municipal water utilities requiring 72-hour turnaround and all contracts allowing CPI-U price escalation at renewal.
