NIGP 50065: Soap Tanks and Automatic Supply Injection Systems

NIGP 50065 Soap Tanks And Automatic Supply Injection Systems, an Item code, encompasses biodegradable liquid detergents and chemical supply systems for automated fleet wash operations—specifically the coach wash products and delivery infrastructure that transit agencies deploy for bus cleaning at maintenance facilities. State and local governments procure under this code primarily through transit authorities and municipal transportation departments seeking specialized soap formulations that meet strict dilution ratios, environmental compliance standards, and compatibility requirements with existing automated wash equipment. Vendors must demonstrate sustained manufacturing or supply experience, hold customer references from comparable transit operations, and provide technical documentation and samples for pre-award testing and approval. The City of Detroit Department of Transportation has emerged as an active buyer, issuing multiple RFQs for coach wash detergent to support its bus fleet maintenance program.

Detroit's two recent RFQs—posted February 4, 2026 (due February 19) and February 27, 2026 (due March 10)—represent the primary recent activity under this code. Both solicitations seek biodegradable, free-rinsing detergent in 30-gallon or 275- to 330-gallon totes for two-year contracts with optional one-year renewals, with annual consumption estimated at 8,250 gallons (30 totes). Qualified bidders must hold four years' minimum experience supplying transit-grade degreasers and provide three customer references from transit agencies. The City of Detroit applies equalization credits ranging from 1 to 5 percent for certified Detroit-based, small, and micro businesses, with award criteria tied to lowest equalized bid not exceeding 12 percent above the lowest responsible bid or $100,000, whichever is less. All successful respondents must clear pre-award requirements including notarized affidavits, City Treasury income and revenue tax clearance, and comprehensive insurance coverage (General Liability $1,000,000 per occurrence/$2,000,000 aggregate; Automobile Liability $1,000,000 combined single limit; Errors and Omission/Cyber Liability $1,000,000 per claim/$5,000,000 aggregate). Responses are submitted through the Bonfire procurement portal; no pre-bid conferences are scheduled for either solicitation.
