UNSPSC 15101801: Biodiesel

A type of biofuel that is made with the ingredients in vegetable oil, such as soybean oil and it is most widely used along with bioethanol.

UNSPSC 15101801 Biodiesel, a Commodity code, encompasses the procurement of biodiesel fuels and renewable diesel blends by state and local governments for fleet operations, transit systems, and municipal vehicle fleets. State and local buyers are purchasing biodiesel and renewable diesel products—including B5 blends, RD99 renewable diesel, and bulk renewable identification number (RIN) credit management services tied to alternative fuel consumption—to support sustainability mandates, reduce emissions, and integrate alternative fuels into existing diesel-powered vehicle networks. Recent solicitations show counties, cities, transit authorities, and state departments procuring renewable diesel for routine fleet fueling, with work spanning delivery logistics, fuel inventory monitoring, and compliance reporting under federal and state clean-fuel standards.

The issuing-body mix includes county general-services departments (Solano County, California), state procurement offices (Washington State Department of Enterprise Services, South Dakota, Illinois Department of Transportation), transit authorities (Orange County Transportation Authority, City of Albuquerque ABQ Ride), cities (Santa Monica, Nashua, Long Beach), and cooperative purchasing groups spanning multiple municipalities (Capitol Region Purchasing Council in Connecticut, Berkshire Regional Group Purchasing Program in Massachusetts). Representative recent opportunities include Solano County's IFB 405060226 for bulk renewable diesel and unleaded gasoline delivery to nine county fuel storage tanks across six locations, with bids due July 20, 2026, and annual consumption of approximately 70,000 gallons of renewable diesel; the City of Santa Monica's ITB for renewable diesel fuel delivery to six city facilities with five-year term and estimated annual volume of 50,000 gallons; and the City of Nashua's IFB for B5 biodiesel fuel supply to its transit system (10,000 to 20,000 gallons annually, July 1, 2026 through June 30, 2027). Geographic activity centers on California (Solano, Sacramento, Santa Monica, Orange County), the Northeast (Massachusetts, Connecticut, New Hampshire), the Pacific Northwest (Washington), and upper Midwest (South Dakota, Illinois), with procurement occurring year-round across municipal, county, and state fleets seeking to meet air-quality standards and renewable-fuel mandates.
