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:  501

Narrative:      Export Information Code Missing

Severity:        Fatal

Reason:         The Export Information Code was not reported.

Resolution:  An Export Information Code must be reported on every shipment.

Verify the Export Information Code, correct the shipment and resubmit.

Response Code:  522

Narrative:      Shipping Weight Exceeds Max Air Threshold

Severity:        Fatal

Reason:         The Mode of Transportation is reported as Air and the Shipping Weight reported exceeds the maximum threshold allowed for an air shipment.

Resolution:  The maximum Shipping Weight allowed for an air shipment is 105,000 kilograms (for other than fly-away aircraft).

Verify the Shipping Weight and Mode of Transportation, 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.
