In September 2019, the United Stated exported 89,000 barrels per day (b/d) more petroleum (crude oil and petroleum products) than it imported, the first month this has happened since monthly records began in 1973. A decade ago, the United States was importing 10 million b/d more petroleum than it was exporting. Long-running changes in U.S. trade patterns for both crude oil and petroleum have resulted in a steady decrease in overall U.S. net petroleum imports.
Net petroleum trade is calculated as total imports of crude oil and petroleum products less total exports of crude oil and petroleum products. Although the United States currently imports more crude oil than it exports, it exports more petroleum products than it imports, resulting in a net total petroleum exports.
