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:  147

Narrative: Routed Export Indicator Missing

Severity: Fatal

Reason: The Routed Export Indicator is missing.

Resolution: A routed export transaction is a transaction in which the Foreign Principal Party in Interest (FPPI) authorizes a U.S. agent to facilitate the export of items from the United States and to prepare and file Electronic Export Information (EEI).  You must report the Routed Export Indicator as Yes or No. 

Verify whether or not this is a routed export transaction, correct the shipment and resubmit.

Response Code:  171

Narrative: Transportation Reference Number Not Allowed for MOT

Severity: Fatal

Reason: The Transportation Reference Number is not allowed to be reported for the Mode of Transportation declared for this shipment.

Resolution:  A Transportation Reference Number identifying the carrier’s transportation instrument is required for vessel shipments and allowed for the other major modes of transportation (air, rail or truck). A Transportation Reference Number cannot be reported for a shipment using any other mode of transportation (i.e., mail, fixed or other). 

Verify the Mode of Transportation Code and Transportation Reference Number, 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.
