Exports are 12% of U.S. total economic output, but it could be larger. Only 1% of U.S. businesses export. Even so, the U.S. is the world's fourth largest exporter, after the EU, China and Germany.
Two-thirds of U.S. exports are material goods. The largest sub-category is capital equipment, such as computer equipment, semiconducters and medical equipment. The second largest is industrial machinery and equipment, including plastics, chemicals and petroleum products.
Overall, the U.S. exports less than it imports. That's because imports in consumer goods and automotive products far outweigh exports.
However, the U.S. does export more services than it imports.That's because of U.S. success in exporting intellectual property, such as technical information. The three largest export categories in services are royalties and license fees, travel services and financial services.
