On January 31, 2018, the European Commission (EC) launched a new investigation into subsidized imports of biodiesel from Argentina.  The investigation was initiated based on a complaint filed by the European Biodiesel Board (EBB) on behalf of producers representing over 25 percent of the European Union (EU) biodiesel production.  The EC determined that the complaint includes sufficient evidence that the Argentinean biodiesel producers have benefitted from a number of subsidies granted by the Government of Argentina.  The investigation provides another means for imposing tariffs on biodiesel imported from Argentina following successful challenges to the anti-dumping (AD) duties set in 2013.  In September 2017, the EU reduced the AD duties for Argentinean biodiesel to between 4.5 and 8.1 percent, from initial rates of 22-25.7 percent.
