UNSPSC 15101800: Plant based liquid fuels or biofuels

Fuels made from oil extracted from fruits, roots and stems of plants.

UNSPSC 15101800 Plant based liquid fuels or biofuels (Class) encompasses the procurement of renewable diesel, biodiesel blends, and related alternative fuel products delivered to state and local fleet operations, fuel storage facilities, and transit authorities. State and local governments are buying renewable diesel (RD99), biodiesel-blended fuels, and biofuel products to support vehicle fleets, emergency services, and public works operations under this code; recent solicitations show a mix of bulk fuel supply contracts with delivery and monitoring services, standalone fuel procurement agreements, and RIN credit management for renewable natural gas attribution. Issuing bodies span state transportation departments, county general services divisions, city public works and fleet management departments, transit authorities, and state air quality boards. Counties, cities, and state agencies are the primary solicitors; the County of Solano, City of Santa Monica, cities of Cambridge and Newton, State of California CARB, Washington State Department of Enterprise Services, City of Albuquerque, and various state departments appear across multiple recent opportunities.

Recent activity concentrates in California, Massachusetts, Washington, South Dakota, and Illinois. Representative recent solicitations include the County of Solano General Services Department–Fleet Operations issuing IFB 405060226 for bulk unleaded gasoline (CARB-compliant) and renewable diesel (RD99) supply, delivery, and Veeder-Root tank monitoring to nine fuel storage locations serving 700+ fleet assets, with bids due July 20, 2026; the City of Santa Monica Public Works Department issuing ITB 4511 for renewable diesel fuel (RD-99 CLRRF) delivery to six municipal facilities (City Yards, Beach Maintenance, Fire Stations 1–5) over five years with an estimated annual spend of $1,250,000; the Berkshire Regional Group Purchasing Program soliciting cooperative bids covering gasoline (FY27-14), diesel fuel (FY27-15), heating oil (FY27-16), and liquid propane (FY27-17) for 32 Berkshire County municipalities in Massachusetts, with bids due April 17, 2026; and the State of South Dakota Office of Procurement Management issuing IFB 26IFB19786 for tankwagon and transport fuel deliveries (undyed diesel, dyed diesel, E10/gasoline, E30, B5 biodiesel) to 88 primary storage locations plus additional hubs across the state. The Washington State Department of Enterprise Services reissued solicitation 09225-02 for statewide bulk lubricants, greases, and diesel exhaust fluid (DEF) contracts structured in four categories with historical annual sales of $5.1 million and bids due July 30, 2026. Geographic spread reflects strong activity in the West (California, Washington) and emerging procurement in the Northeast (Massachusetts), Midwest (Illinois, South Dakota), and Southwest (New Mexico), with local-vendor preferences and set-asides present in several jurisdictions.
