UNSPSC 15121529: Refrigerating machine oil

A type of lubricant made of mineral oil used on the cylinders of refrigeration compressors and other refrigeration machinery.

UNSPSC 15121529 Refrigerating machine oil is a Commodity code that covers supplies of compressor oils, synthetic lubricants, and related products used in HVAC and refrigeration system maintenance by state and local agencies. State and local governments procure refrigerating machine oil primarily as a consumable input to routine and emergency HVAC maintenance performed by in-house technicians and contracted service providers at transit facilities, county maintenance stations, and municipal buildings. The issuing bodies span transit authorities, state transportation departments, and city consolidated governments, with activity driven by seasonal preventative maintenance schedules and operational demands at distributed facility networks. Scope varies from bulk supply agreements serving system-wide HVAC needs to component replacements within individual emergency repair jobs; recent solicitations emphasize compliance with prevailing wage, insurance, and safety documentation requirements, particularly where federal transit funding applies.

Geographic activity appears concentrated in California and Texas, with secondary presence in Georgia. The Fort Worth Transportation Authority (Trinity Metro) issued IFB 26T023 on April 1, 2026, requesting refrigerant supply and cylinder exchange services for R-134a and R-407c with a bid deadline of April 30, 2026. The Columbus Consolidated Government in Georgia posted an RFB on February 16, 2026, for oils and lubricants on an as-needed basis to support METRA Transit System operations, due March 11, 2026. The California Department of Transportation (Caltrans) issued RFQ 08A4007 on June 26, 2026, for routine and non-routine HVAC services across nine maintenance stations in Riverside County with a Small Business set-aside, due July 10, 2026, capped at $484,000 over a three-year term. Transit authorities and state transportation departments appear as repeat buyers, though no single jurisdictional cluster dominates the recent opportunity set.
