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:  515

Narrative:     ECCN Must be Formatted NANNN

Severity:       Fatal

Reason:         The Export Control Classification Number (ECCN) was not reported in the correct format.

Resolution:  The Export Control Classification Number (ECCN) must be reported in a NANNN format, where N is a numeric character and A is an alpha character. 

Verify the ECCN, correct the shipment and resubmit.

Response Code:  850

Narrative:     Improbable Foreign/Domestic Origin

Severity:       Verify

Reason:         For the reported Schedule B/HTS Number, the Domestic/Foreign Origin Indicator is improbable for this commodity.

Resolution:  Certain products are highly unlikely to be either of domestic origin or of foreign origin.  This might indicate either a keying error or misclassification of the product. 

Verify the Domestic/Foreign Origin Indicator and the Schedule B/HTS Number, correct the shipment and resubmit (if necessary).  If the information is verified correct as reported, no action is necessary.

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.
