UNSPSC 25174004: Engine coolant

UNSPSC 25174004 Engine coolant, a Commodity code, covers the supply of bulk and packaged antifreeze and coolants to state and local fleets, transit authorities, school districts, and public works agencies. State and local governments procure engine coolant primarily as recurring fleet maintenance supplies, soliciting pre-mixed 50/50 formulations and concentrate products in 55-gallon drums and bulk quantities, with specifications tied to manufacturer standards (Cummins CES 14603, API Service Requirements) and delivery windows measured in hours to days. The buying mix spans regional transit authorities, county and municipal transportation departments, school districts operating bus and equipment fleets, and county facilities departments; Orange County Transportation Authority, City of Detroit Department of Transportation, Pinellas County School District, and Rockwood School District appear as repeat buyers in recent activity.

Recent opportunities span California, Florida, Michigan, and Wisconsin. The Orange County Transportation Authority issued RFQ 250454 in October 2026 for bulk antifreeze delivery to two locations (Garden Grove and Santa Ana) with a $92,000 estimated value over two years and a September 9, 2026 response date, requiring 48-hour standard delivery and Cummins CES 14603 compliance. The City of Detroit Office of Contracting and Procurement posted RFQ 551483 (due October 9, 2026) for low-silicate, phosphate-free ethylene glycol antifreeze in both premixed and concentrate formulations across bulk and drum delivery, estimated at 24,000 gallons annually, with Detroit-based business equalization credits of one to five percent available. Pinellas County School District issued ITB 26-AM-018 (due August 26, 2026) for petroleum lubricants and antifreeze products valued at approximately $135,000 annually across four bus maintenance facilities in the Tampa Bay area, with contract performance October 28, 2026 through October 27, 2027. Rockwood School District issued a one-year RFB for shop fluids including antifreeze (bids due September 24, 2026). A Waukesha County proposal request (due August 27, 2026) sought on-site collection and recycling services for used antifreeze, representing reverse-logistics demand at the county facilities level.
