NIGP 50530: Chemicals (Not Otherwise Classified)

NIGP 50530, Chemicals (Not Otherwise Classified), is an Item code under which state and local governments procure specialized chemicals for water treatment, wastewater treatment, facility maintenance, and environmental remediation—buying products such as sodium hypochlorite, ferric chloride, magnesium hydroxide, sodium permanganate, liquid caustic soda, liquid hydrogen peroxide, and proprietary cleaning compounds on firm or indexed pricing structures tied to delivered per-unit rates. Cities and counties dominate the issuing body mix, with water and wastewater utilities representing the primary end users; school districts and solid-waste districts occasionally solicit under the code for janitorial and operational chemical supplies. Recent solicitations show repeat activity from Connecticut municipalities (Town of Manchester, City of Meriden), Florida jurisdictions (City of Cocoa, City of Tolleson, Hillsborough County, Sarasota County), Georgia counties (Gwinnett County, Colquitt County School Nutrition), and Texas cities (City of Dallas), with procurement spanning delivery timeframes of 48 to 72 hours on as-needed bases and contract terms typically running one to three years with firm pricing for initial periods and PPI-indexed adjustment options thereafter.

Representative recent opportunities include the City of Cocoa issuing ITB B2617COC for liquid sodium hypochlorite (12.0–12.5% concentration, NSF 60/61 certified) with responses due September 23, 2026, and a 5% local preference for Brevard County contractors; the Town of Manchester issuing ITB 25/26-59 for eleven line items of water treatment chemicals (sodium hypochlorite, PACI coagulant, fluosilicic acid, zinc orthophosphate, and others) with bids due May 22, 2026 at 11:00 a.m.; the City of Dallas soliciting a thirty-six-month ID/IQ service agreement for sewer odor and corrosion control chemicals (ferrous iron salt, ferrous chloride, bioxide) with an estimated value of $10 million and mandatory SBE participation goals under its DRIVE policy, responses due June 26, 2026; and Colquitt County School Nutrition issuing an IFB for kitchen and janitorial chemicals (freezer cleaners, floor drain treatments, NSF-compliant products) with bids due June 15, 2026. Delivery to single or multiple facility locations, compliance with AWWA and NSF standards, and bonding requirements are standard across solicitations; Build America Buy America Act compliance appears in recent municipal water solicitations.
