NIGP 18012: Ammonium Hydroxide (Aqua Ammonia) and Amines

NIGP 18012 Ammonium Hydroxide (Aqua Ammonia) and Amines, an Item code, covers bulk chemical supply contracts that state and local water utilities, wastewater facilities, and energy operations use for treatment and emissions control. Recent activity shows municipalities procuring aqueous ammonia and ammonium-based products through formal competitive bidding for facility-level operations—water treatment facilities sourcing treatment chemicals under long-term supply agreements and electric utilities acquiring specialized aqueous ammonia for nitrogen oxide suppression at power generation sites. Issuing bodies include municipal water and wastewater departments and city electric utilities, each managing high-volume, recurring chemical supply needs with multi-year contract terms and strict quality and delivery specifications.
