UNSPSC 15121530: Heat transfer oil or fluid

A type of heat transfer fluid, generally in a closed loop system, used to heat or cool process equipment. It is comprised of refined mineral oil or synthetic oil with quality appropriate for thermal transfer medium.

UNSPSC 15121530 Heat transfer oil or fluid, a Commodity code, actually tracks state and local procurement of industrial lubricants, maintenance fluids, and fuel products rather than specialized heat-transfer applications alone. State and local governments buy motor oils, greases, diesel exhaust fluid (DEF), gear oils, and bulk engine lubricants through this code to supply distributed fleet and equipment maintenance needs across multiple agencies, school districts, and transportation departments. Issuing bodies include state procurement offices managing statewide supply contracts, county school districts operating distributed fueling infrastructure, and state departments of transportation and enterprise services. Recent solicitations show a mix of competitive open bids and volume-based supply agreements, with contracts typically structured as firm fixed-price or NYMEX-indexed pricing models and spanning one to four years with renewal options.

Activity is concentrated in the Pacific Northwest and Southeast. Washington State Department of Enterprise Services posted a statewide solicitation (09225-02, due July 30, 2026) for bulk lubricants, greases, gear oils, and DEF across four product categories, with historical annual sales of approximately $5.1 million and a forty-eight-month term commencing September 1, 2026, including a potential forty-eight-month extension and a 10 percent DBE participation goal. South Dakota's Office of Procurement Management issued IFB 26IFB19994 (due November 4, 2026) for motor oil, grease, and related fluids to supply state agencies statewide. Hillsborough County Public Schools (Florida) awarded an ITB for ultralow sulfur diesel fuel (26205-ITB-DST) to multiple vendors following nine competitive bids, with an estimated annual contract value of $5.5 million, delivery to eleven sites, and per-gallon markups over NYMEX futures pricing. Cobb County School District (Georgia) solicited gasoline and diesel fuel delivery to multiple district fueling locations (PE63310NONST2027000000224, due September 30, 2026).
