Biodiesel Labeling Requirement

Biodiesel fuel retailers may not advertise or offer for sale fuel labeled as pure biodiesel unless the fuel contains no other type of petroleum product, is registered as biodiesel fuel with the federal government, and meets all applicable ASTM specifications. Retailers also may not sell fuel labeled as a biodiesel blend unless the fuel contains at least 2% pure biodiesel fuel, the blend percentage is identified, and the fuel meets all applicable ASTM standards. (Reference Wisconsin Statutes 168.14(2)-168.14(3))
