Licenses from the Department of State or Department of Commerce may be required to export.  A key in determining whether an export license is needed from the Department of Commerce is knowing whether the item you intend to export has a specific Export Control Classification Number (ECCN). The ECCN is an alpha-numeric code, e.g., 3A001, that describes the item and indicates licensing requirements. All ECCNs are listed in the Commerce Control List (CCL) (Supplement No. 1 to Part 774 of the EAR) which is available on the Government Printing Office website.
