There could be several reasons why a GMR might not be valid when you check-in. The most common reasons and how to correct them, are as follows -
Customs declaration ID does not exist
Customer needs to check they have the correct declaration reference for the type of movement.
The customs declaration ID has already been used in another GMR
Customer needs to check they have the correct declaration reference and the reference provided is unique for that movement.
Vehicle ID provided does not match the GMR ID
The vehicle registration does not match the vehicle registration on the GMR. You will need to update your GMR in the CustomsLink Port Pass Builder to show the correct vehicle registration.
Trailer ID provided does not match the GMR ID
The trailer ID does not match the trailer identifier on the GMR. You will need to update your GMR in the CustomsLink Port Pass Builder to show the correct trailer ID.
This type of declaration cannot be used for this direction of travel
Check the correct direction of travel and type of declaration have been selected.
Do Not Proceed – The GMR ID is not ready for entry to the port
The GMR is not in the correct status to be checked in. You will need to update your GMR in the CustomsLink Port Pass Builder before returning to the Port
The GMR ID is already checked in with HMRC
The GMR has already been checked in. It cannot be re-used. You will need to update your GMR in the CustomsLink Port Pass Builder with a new GMR before returning to the Port.
The GMR ID could not be found at HMRC
The GMR is not found on the GVMS. You will need to check the information provided to your carrier is correct.
No GMR has been presented to the Carrier
You cannot board the vessel without a GMR. You will need to contact your Haulage company and ask for a copy of the GMR.
