If electronic export information filing is required but the U.S. Census Bureau’s Automated Export System or AESDirect is unavailable, the mailer may ship the goods but is responsible for providing the appropriate AES Downtime Citation instead of an ITN. This citation includes the word “AESDOWN,” the mailer’s AES filer identification number, and the date: for example, “AESDOWN 123456789 09/30/2009.”
