In the first half of 2016, the United States exported 4.7 million barrels per day (b/d) of petroleum products, an increase of 500,000 b/d over the first half of 2015 and almost 10 times the crude oil export volume. While U.S. exports of distillate and gasoline increased by 50,000 b/d and nearly 140,000 b/d, respectively, propane exports increased by more than 230,000 b/d. Propane surpassed motor gasoline to become the second-largest U.S. petroleum product export, after distillate.
