Tips on How to Resolve AES Response Messages

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:  075

Narrative:    SRN on File; Action Not Allowed 

Severity:      Fatal

Reason:      The Shipment Reference Number is already on file in AES.

Resolution:  When the Shipment Filing Action Request Indicator is an Add, the Shipment Reference Number cannot have been reported on a previous filing in AES. The reuse of the Shipment Reference Number is prohibited.

Verify the action requested and the Shipment Reference Number, correct the shipment and resubmit.

Response Code:  511

Narrative:     Mode of Transportation Not Allowed for License Code

Severity:       Fatal

Reason:       The Mode of Transportation reported is not valid for the License Code/License Exemption reported.

Resolution:  The Mode of Transportation must be compatible with the reported License Code/License Exemption. See ‘Appendix F, License and License Exemption Type Codes’ to determine the appropriate Mode of Transportation and License Code/License Exemption combination.

Verify the Mode of Transportation and License Code/License Exemption, correct the shipment and resubmit.

For a complete list of AES Response Codes, their reasons, and resolutions, see Appendix A – Commodity Filing Response Messages.

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.
