Exporting is a privilege, not a right. Before you begin exporting you have to know where your product or service stands in terms of export controls.
The U.S. controls exports of tangible items, technology, software and some services. There are several government agencies that control exports. Three government agencies that control the majority of exports from the U.S. are the U.S. Department of Treasury, the U.S. Department of State, and the U.S. Department of Commerce.
