Identifying and handling HMRC error codes – AEB Help Center

You have received an error code from HMRC and want to modify your declaration for resending? Here you will learn how to proceed:

Proceed as follows if you encounter HMRC customs errors

Please note: This is an error coming from HMRC regarding the information submitted to customs, not an error generated from the AEB solution.

Open the customs declaration for which you have received an error message from HMRC.
Read details about the error code: In the assistant pane on the right, you can find a description of the cause/solution of your error.
Click on the Show more details link to research further details of the error code. The Customs information sheet opens.
In the Customs messages field group, select the respective error message, then click Open.
- If there is no cause/solution shown in the assistant area, you may also research the error code via HMRC’s website: CHIEF error codes - GOV.UK. 
Once you have located and read your error message, modify your declaration with the correct information and resend it to the authorities.
If you follow the advice and still receive a further error message you may need to raise a request with HMRC as to why they are rejecting your declaration data submission. Is this the case, raise a request with HMRC: chief.operations@hmrc.gsi.gov.uk

Open the declaration in question and switch to the Customs information sheet.
In the Customs messages field group, select the CUSDEC04A or CUSRES04A message, then click Open.

The message opens in a new tab.
From this screen, open the Customs message menu at the top and select the Download message in original format option.
Save the files in your Downloads folder on your local computer.
From your Downloads folder, copy these files and attach them to your email to HMRC.
