UNSPSC 15121807: Antifreeze

A solution used in internal combustion engines and many other heat transfer applications designed to prevent a rigid enclosure from undergoing physical stresses and catastrophic deformation due to the expansion that occurs when water turns to ice.

UNSPSC 15121807 Antifreeze (Commodity) covers the supply of pre-mixed and concentrate ethylene glycol antifreeze products that state and local governments procure for fleet vehicle maintenance and equipment servicing. Recent solicitations show state and local buyers purchasing antifreeze in bulk quantities (55-gallon drums and tanker delivery), with formulations ranging from Cummins-approved standards to low-silicate, phosphate-free, premium-quality specifications. The code also captures ancillary services including used antifreeze collection and recycling. Issuing bodies span transit authorities, city transportation departments, school districts, county facilities management, and state environmental programs. Orange County Transportation Authority, the City of Detroit Department of Transportation, Pinellas County School District, and the Santa Fe Solid Waste Management Agency have all solicited antifreeze supply contracts in the past two months. Transit and fleet operators dominate the buying pattern, though school districts and county facilities management also appear as repeat buyers.

Recent activity concentrates in California, Florida, Michigan, New Mexico, and Maryland, with secondary activity in Wisconsin and Texas. The Orange County Transportation Authority (OCTA) awarded a two-year bulk antifreeze supply contract valued at $92,000 under RFQ 250454, responding to quotes due September 9, 2026 for pre-mixed 50/50 antifreeze delivered to Garden Grove and Santa Ana with forty-eight-hour standard delivery and monthly emergency twenty-four-hour turnaround capability. The City of Detroit Office of Contracting and Procurement requested quotes for low-silicate, phosphate-free ethylene glycol antifreeze in both concentrate and premixed formulations (RFQ 551483, quotes due October 9, 2026) for the Detroit Department of Transportation's Extended Service Interval program, with estimated annual usage of approximately 24,000 gallons across bulk and drum configurations and Detroit-based business equalization credits available. Pinellas County School District issued an ITB for petroleum lubricants and antifreeze (ITB #26-AM-018, bids due August 26, 2026) valued at approximately $135,000 annually for delivery to four vehicle maintenance locations across the district. Maryland Environmental Service issued a statewide RFP for used oil and antifreeze collection and recycling services across 85 collection sites, based on 2025 collections of approximately 27,000 gallons of used antifreeze (RFP issued April 28, 2026).
