U.S. imports of biomass-based diesel, which include biodiesel and renewable diesel, totaled 14.1 million barrels in 2017, a 36% decrease from 2016. Although increasing Renewable Fuel Standard (RFS) targets have driven increased biomass-based diesel demand in recent years, imports fell in 2017 largely because of U.S. Department of Commerce (DOC) import duties imposed on foreign biodiesel volumes sourced from Argentina and Indonesia, two of the leading exporters of biodiesel.
