Border Security. Exporters. Definition. For C-TPAT purposes, an exporter is defined as: A person or company who, as the principal party in interest in the export transaction, has the power and responsibility for determining and controlling the sending of the items out of the United States.
In common usage, export means to send something from your country to a different country, and import means to bring something from a foreign land to your own. Similarly, in computer terminology, import means to bring a file from a different program into the one you're using, and export means to save a file in a way that a different program can use it. Importing and exporting allow different computer programs to read each others' files.
