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:  141

Narrative:     Port of Unlading Not Allowed For MOT

Severity:       Fatal

Reason:        The Port of Unlading is not allowed for the Mode of Transportation reported.

Resolution:  A valid Port of Unlading must be reported for air shipments between the U.S. and Puerto Rico as well as all vessel shipments.  Leave the field blank if any other mode of transportation is reported. 

Verify the Port of Unlading and/or Mode of Transportation, correct the shipment and resubmit.   

Response Code:  643

Narrative:     Quantity 2 Must Be Greater Than Zero

Severity:       Fatal

Reason:        The Schedule B/HTS number reported requires a second Quantity to be reported and the Quantity 2 is missing or reported as zero.

Resolution:  Quantity 2 must be greater than zero.

Verify the Quantity 2, 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.
