U.S. imports of biomass-based diesel in September nearly doubled August volumes, according to the latest figures from the U.S. Energy Information Administration. Imports for September totaled 28.7 million gallons, up from August import volumes of just more than 15 million gallons. U.S. exports of biomass-based diesel, however, fell significantly in September from August. The U.S. exported only 15.9 million gallons of biomass-based diesel in September compared to nearly 29 million gallons in August.

More than half the U.S. imports of biomass-based diesel for September came from Argentina (11.6 million gallons) and Indonesia (nearly 7.1 million gallons), with imports from Germany (4.7 million gallons), Panama (3.36 million gallons), Canada (1.3 million gallons) and South Korea (630,000 gallons) trailing.

September U.S. exports of biomass-based diesel totaling 15.9 million gallons went to Canada (6.6 million gallons), Gibraltar (5.7 million gallons), Spain (nearly 3 million gallons), Peru (420,000 gallons), Australia (252,000 gallons) and Malaysia (42,000 gallons).

U.S. imports of “other renewable diesel” topped more than 25.7 million gallons, with 22.6 million coming from Singapore and 3.1 million gallons from Finland. This is down from more than 36 million gallons in August.

The EIA defines “biomass-based diesel” as “biodiesel and other renewable diesel fuel or diesel fuel blending components derived from biomass, but excluding renewable diesel fuel coprocessed with petroleum feedstocks.” It defines “other renewable diesel” as “diesel fuel and diesel fuel blending components produced from renewable sources that are coprocessed with petroleum feedstocks and meet requirements of advanced biofuels.”
