NIGP 19042: Compounds, Inorganic Chemical

NIGP 19042 Compounds, Inorganic Chemical (Item) covers liquid and solid chemical compounds that state and local governments procure for water and wastewater treatment, road maintenance, and facility operations. Recent state and local solicitations under this code show water utilities and public works departments purchasing calcium chloride for de-icing, magnesium hydroxide slurry for hydrogen sulfide and corrosion control in wastewater systems, solids dewatering and thickening polymers for treatment plants, and road salt for winter maintenance. Issuing bodies include city public works departments, county water authorities, regional water reclamation facilities, county boards of commissioners, and special-purpose water districts. Detroit's Public Works Department, the City of Tallahassee, Gwinnett County Board of Commissioners, and the Brazos River Authority are recent active buyers under this code. Procurement vehicles range from direct RFQ to competitive sealed bidding with multi-year contract terms and renewal options. Local vendor preferences and set-asides appear where jurisdiction policy supports them—Detroit applies equalization credits for Detroit-based businesses, and Tallahassee offers local vendor preference for Leon County-area vendors.

Recent activity concentrates in Michigan, Florida, Georgia, Massachusetts, and Texas. The City of Detroit issued an RFQ for 300,000 gallons of liquid calcium chloride (pH 5, 57–62% CaCl₂ by weight) for ice control, with quotes due October 14, 2026, requiring vendor location within 20 miles of Detroit and 24/7 facility access. The City of Tallahassee solicited magnesium hydroxide slurry via sealed bid (IFB-067-26-CPW) with bids due June 16, 2026, for a five-year initial term with optional two-year renewals, requiring five years' prior experience and ANSI/NSF Standard 60 certification. Gwinnett County sought solids dewatering and thickening polymer on a competitive sealed-bid annual contract (BL076-26) due July 30, 2026, specifying Polydyne Clarifloc SE-1748 as pre-approved product with mandatory bench and full-scale testing for alternatives. The City of Framingham coordinated a cooperative bid for road salt and treated rock salt (PW-1285) across nine Massachusetts municipalities with bids due September 17, 2026. Dallas County and Pasco County posted minimal-detail chemical commodity buys in July and June 2026 respectively, suggesting ongoing replenishment procurement through cooperative or blanket-order mechanisms.
