NIGP 19036: Chemicals, Bulk (Not Otherwise Itemized)

NIGP 19036 Chemicals, Bulk (Not Otherwise Itemized) is an Item code covering discrete chemical products that state and local governments procure for water treatment, wastewater treatment, facility maintenance, and specialized operations—typically in bulk quantities and on recurring supply contracts with firm pricing and delivery commitments. Recent solicitations show state and local buyers purchasing liquid and dry treatment chemicals (sodium hypochlorite, magnesium hydroxide, aluminum sulfate, ammonium sulfate, liquid chlorine, ferrous compounds, polymers), corrosion and odor control additives, road-treatment chemicals (calcium chloride), janitorial and cleaning products, and specialty chemicals such as windshield washer solvent and pool treatments, almost always requiring NSF or ANSI/NSF 60 certification when the product enters drinking water systems.

Issuing bodies span water utilities (municipal water departments, regional water authorities such as Eastern Municipal Water District and Great Lakes Water Authority), wastewater treatment authorities, county and city public works departments, school districts, transit authorities, and special-purpose districts. Cities of Tallahassee, Manchester Connecticut, Griffin Georgia, and Milpitas California have posted multiple bids within recent months. Geographic concentration runs heaviest in Florida, Georgia, Connecticut, California, and Michigan, though recent opportunities span Texas, Oregon, Maryland, and others. Representative recent activity includes the City of Tallahassee ITB for magnesium hydroxide slurry (five-year supply contract, due June 16, 2026); Town of Manchester Connecticut ITBs for water treatment chemicals and wastewater treatment chemicals (both due May 22, 2026); the City of Milpitas IFB for MRO supplies including chemicals across five categories (due August 4, 2026); the Great Lakes Water Authority RFQ for bulk sodium bisulfite delivery to three Michigan facilities (due May 11, 2026); Eastern Municipal Water District RFP for liquid ammonium sulfate (due March 19, 2026); and the City of Dallas thirty-six-month ID/IQ agreement for sewer odor and corrosion control services including ferrous iron salt and ferrous chloride injection (due June 26, 2026, $10 million estimated value). Contracts typically run one to five years with firm pricing for year one, subsequent adjustments capped at CPI or documented cost increases, and performance bonds, insurance requirements (commonly $1 million general liability minimum), and NSF/AWWA compliance certifications mandatory for potable-water applications.
