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 is a Commodity code covering antifreeze and coolant products that state and local governments procure for fleet maintenance and vehicle operations. State and local buyers are sourcing antifreeze as a component of broader automotive maintenance supply contracts, as a standalone product for fleet management, and as a waste stream collection and recycling service. The code sees activity across transit authorities, city purchasing departments, county agencies, and state environmental services.

Recent opportunities span multiple states and jurisdictions. The City of Santa Fe Procurement Office, on behalf of the Santa Fe Solid Waste Management Agency, issued ITB FY27-ITB-001 (response due July 31, 2026) for motor oils, lubricants, antifreeze, and related products in multiple units of measure, with New Mexico Resident Business and Resident Veteran Business preferences available. The City of Tampa Purchasing Department posted RFQ 26-P-00418 (due July 22, 2026) for inventory automotive shop equipment and supplies including antifreeze as one of 19 line items for use across Hillsborough County departments. The Dallas Area Rapid Transit Authority solicited bids for Oil Coolant 50/50 Dex-Cool under contract 2097591 (due January 28, 2026). The Maryland Environmental Service issued an RFP (due May 18, 2026) for statewide used oil and antifreeze collection and recycling services across 85 collection sites, with pricing structured per gallon for antifreeze. Geographic activity is concentrated in Texas, New Mexico, Florida, and Maryland, with the Maryland solicitation representing a distinctive waste-stream application rather than new-product supply.
