How secure are my transmissions to AES? What about Internet filing to AES?
The Automated Export System (AES) accepts transmissions in several Electronic Data Interchange (EDI) formats over secure dedicated telephone lines (via 800 numbers). The service centers that accept Internet transmissions pass your transmissions through to Customs in an appropriate EDI format, and each provider addresses these concerns individually. U.S. Customs does not plan to accept Internet submissions on an open basis at this time.
