NIGP 578: Miscellaneous Products (Not Otherwise Classified)

NIGP 578 Miscellaneous Products (Not Otherwise Classified) is a Class code capturing a broad range of unclassified goods and materials that state and local governments procure when existing NIGP categories do not apply — from tire-derived aggregate for landfill operations and sodium bisulfite for water treatment to food service disposables, construction materials, and specialized equipment like GNSS rovers and traffic signal hardware.

State agencies, counties, cities, school districts, special-purpose districts, and water authorities issue solicitations under this code across the country. Recent activity spans California (County of Orange, City of Palo Alto), Connecticut (City of Meriden), Maryland (Charles County), Florida (Orange County, Collier County, Tucson), Utah (multiple districts and municipalities), Massachusetts, New Jersey, Texas, and Pennsylvania. The County of Orange in California is a repeat issuer, soliciting for tire-derived aggregate (IFB due July 27, 2026), GNSS survey equipment (IFB due May 29, 2026), and Toyota forklift repair services (IFB due June 26, 2026). The City of Meriden, Connecticut has posted multiple bids under this code for laboratory testing services, flooring replacement, food service supplies, chemical supply, and building maintenance. Procurement activity includes IFBs, RFPs, RFQs, and ITBs reflecting the diversity of goods and services the code encompasses. Current representative solicitations include the County of Orange's request for 3,100 tons of tire-derived aggregate for Olinda Alpha Landfill in Brea, California (IFB 2993097811NA, due July 27, 2026); Charles County, Maryland's design-build RFP for wastewater treatment plant surge-management infrastructure with a 40-foot diameter standpipe (due October 1, 2026); the City of Meriden's RFP for food service paper goods and disposables to serve 8,200 students across 13 school sites ($210,000 estimated annual value, due July 16, 2026); and Tucson Water's IFB for emergency bottled water supply (due July 6, 2026, ARPA-funded). Set-aside programs appear frequently — Orange County applies 5 percent OCLSB and DVBE preference deductions capped at $100,000; Connecticut jurisdictions impose 25 percent SBE and 6.25 percent M/W/DisBE spending goals on school and municipal projects; Maryland offers MWBE subcontractor participation targets; and prevailing wage requirements apply to public-works-related procurements in Connecticut and other states.
