Tips on How to Resolve AES Response Messages

Fatal Error Screen - Large

When a shipment is filed to the AES, a system response message is generated and indicates whether the shipment has been accepted or rejected.  If the shipment is accepted, the AES filer receives an Internal Transaction Number (ITN) as confirmation.  Though the shipment is accepted, the filer may still receive a Verify Message, Compliance Alert, Informational Message or Warning Message along with their ITN.  However, if the shipment is rejected, a Fatal Error notification is received and must be corrected to receive a valid ITN. 

To help you take the appropriate action for the different AES Response Messages, here are some tips on how to address the most frequent messages that were generated in AES for this month.

Response Code:  103

Narrative:    Estimated Date of Export > 120 Days in Future

Severity:       Fatal

Reason:        The Estimated Date of Export reported was more than 120 days in the future.

Resolution:  AES cannot accept an Estimated Date of Export more than 120 days before the anticipated departure of the shipment.

Verify the Estimated Date of Export, correct the shipment and resubmit.  

Response Code:  175

Narrative:    Fly-Away Must be MOT = 40

Severity:       Fatal

Reason:        The Carrier ID (SCAC/IATA) is reported as a fly-away aircraft and the Mode of Transportation is not Air (MOT = 40).

Resolution:  Carrier Code ** or 99O can only be reported to identify an aircraft being exported under it’s own power (fly-away) with a Mode of Transportation for Air (MOT = 40).

Verify the Mode of Transportation and the Carrier ID (SCAC/IATA), correct the shipment and resubmit.

It is important that AES filers correct Fatal Errors as soon as they are received in order to comply with the Foreign Trade Regulations. These errors must be corrected prior to export for shipments filed predeparture and as soon as possible for shipments filed postdeparture but not later than five calendar days after departure.
