"March 2010 Import Highlights: May 27, 2010" Monthly data on the origins of crude oil imports in March 2010 has been released and it shows that three countries exported more than 1.00 million barrels per day to the United States (see table). The top five exporting countries accounted for 66 percent of the United Staters crude imports in March while the top ten sources accounted for approximately 86 percent of all U. S. Crude imports.

Total imports (includes refined product) were Canada, 2.517 million, Mexico 1.265, Saudi Arabia 1.149, Venezuela 1.061 and Nigeria 0.962.

Looked at another way (July figures),

U. S. Crude Oil imports- 9.783
U. S. Petroleum Product Imports- 3.132
