Provide the previous document in this way if the goods have been presented to Customs, but there is a service interruption in the Transit Declaration Service or the Arrival and exit declaration service (AREX) when you try to submit an import declaration. Do this, if Customs has informed of a service interruption, but you can’t wait for it to end because you have to submit a declaration to enable the transport of the goods to continue.

If a declaration submitted as a message or through the Customs Clearance Service is rejected, the reason for the rejection may be that the status of the previous document is incorrect. This means that the state of the previous declaration is not “accepted” for import clearance.

When you are lodging a standard customs declaration (A), the declaration may be rejected, if the previous document has not yet been presented to Customs, or Customs is still processing it. In such cases, you can contact the transport company and ask them to notify you when the declaration state is “Accepted”.

When you are lodging an advance customs declaration (D), the declaration may be rejected, if the previous document has already been presented to Customs. Re-enter “A - Standard customs declaration” as the additional declaration type, and send the declaration to Customs again.

If Customs has taken the declaration in for processing, and if it has been given an MRN, it is no longer possible to amend the additional declaration type.

If the declaration is rejected because the MRN is not found in Customs’ service, check the MRN and send the declaration to Customs again.

You can check the status of the previous document also in the MRN Search, if the previous declaration is an entry summary declaration, summary declaration for temporary storage or customs warehousing declaration.

If the state of the previous declaration is “accepted” for import clearance, but you still receive an error notification, you can contact Customs’ Electronic Service Centre.


If an incorrect MRN has been entered for the entry summary declaration or the summary declaration for temporary storage or an incorrect goods item number related to it has been entered in the customs declaration, proceed as follows:
