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.

Fatal Error Response Code:  523

Narrative:      Schedule B/HTS Number Not Allowed for HH Goods

Severity:        Fatal

Reason:         When the Export Information Code is reported as HH for household goods, a Schedule B/HTS Number is not allowed. 

Resolution:  The Schedule B/HTS Number is not allowed to be reported when the Export Information Code is HH for household goods.   

Verify the Export Information Code and Schedule B/HTS Number combination, correct the shipment and resubmit.

Response Code:  105

Narrative:      Mode of Transportation Unknown

Severity:        Fatal

Reason:         The Mode of Transportation Code reported is not valid in AES.

Resolution:  The Mode of Transportation Code reported must be one recognized in AES and listed in the ‘Appendix T, Mode of Transportation Codes’.

Verify the Mode of Transportation Code, 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.
