The Automated Export System (AES) is the system used by U.S. exporters to electronically declare their international exports, known as Electronic Export Information (EEI), to the Census Bureau to help compile U.S. export and trade statistics. This information is also shared with the Bureau of Industry and Security, the Directorate of Defense Trade Controls, and other federal agencies involved in monitoring and validating U.S. exports. Formerly this declaration was only made on paper on the Shipper's Export Declaration form.
Currently an exporter can file the EEI electronically to the AES using the AESDirect website, the AESPCLink software, or other AES-compatible applications. After an EEI/SED is successfully filed and processed, the shipper receives an Internal Transaction Number (ITN) to put on the shipping documents, as a confirmation to any government agent inspecting the cargo prior to departure.
In most cases a shipper can also authorize its freight forwarder, courier company, or other third-party logistics agent to file the EEI on its behalf.
An EEI is generally required when any one commodity on a given shipment exceeds in value. There are four conditions that necessitate filing an EEI regardless of value: a) if the export destination is Cuba, Iran, North Korea, Sudan, or Syria; b) if the shipment requires an export license or permit; c) if it is subject to the International Traffic in Arms Regulations; or d) if it contains rough diamonds. Incidentally, a shipment from the United States to Canada that exceeds in value does not require an EEI unless it falls under conditions b) through d) above.
