NIGP 19090: Solvents (Not Otherwise Itemized)

NIGP 19090 Solvents (Not Otherwise Itemized), an Item code, covers specialty chemical solvents and cleaning agents that state and local governments procure for maintenance, fleet operations, and infrastructure work. Based on recent solicitations, the code captures asphalt extraction solvents, asphalt release agents, and biodegradable degreasers for equipment and facility cleaning. Issuing bodies across the code include city procurement offices and transit authorities. The City of Philadelphia and the City of Detroit (through its Department of Transportation) are active recent buyers, soliciting through micro purchases and formal RFQ processes. Scope varies from one-time or annual supply contracts with fixed dollar caps to multi-year renewable agreements with specified facility delivery locations and technical performance requirements such as VOC compliance and biodegradability.

Philadelphia posted two micro purchase quotes on July 1, 2026—for asphalt extraction solvent (B2727411) and asphalt release agent (B2727408), both due July 15, 2026, with a $45,000 ceiling per contract adjusted annually by CPI-U. Detroit's Office of Contracting and Procurement issued RFQ 540901.3 on behalf of the Department of Transportation on February 27, 2026, seeking biodegradable cleaner degreaser for transit-bus and equipment maintenance across four DDOT facilities; the RFQ, due March 10, 2026, called for a two-year contract with a one-year renewal option and an estimated annual quantity of six totes, with Detroit-based business equalization credits (up to 5 percent) available and prevailing wage and federal compliance required if federal funding applied. Recent activity reflects geographic concentration in the Midwest and Mid-Atlantic, with Philadelphia and Detroit representing the primary recent buyers under this code.
