Prior to December 2015, crude oil exports were restricted to: (1) crude oil derived from fields under the State waters of Cook Inlet of Alaska; (2) Alaskan North Slope crude oil; (3) certain domestically produced crude oil destined for Canada; (4) shipments to U.S. territories; and (5) California crude oil to Pacific Rim countries. The Persian Gulf includes Bahrain, Iran, Iraq, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates. Net imports are calculated using zero for exports of distillate fuel oil with sulfur contents of 0-15 ppm and greater than 2000 ppm. Totals may not equal sum of components due to independent rounding. See Definitions, Sources, and Notes link above for more information on this table.
