Common Transit Convention Movements for Exports: Changes from 1 August 2023

The text that follows is an email from the National Simplifciations team informaing us of the upcoming changes. It is not our own words and has been copied exactly as sent to us.

We are writing to you as an Authorised Consignor for Transit to set out some important changes.

When full customs controls were implemented after exiting the EU, all UK transit users had a choice of including either the Export Declaration references (DUCRs) or a singular Transit Declaration reference (TAD MRN) in their Goods Movement Reference (GMR) when exporting goods via an Arrived Export location (e.g. Dover and Eurotunnel). However, when a TAD MRN is used, it is impossible to verify via Goods Vehicle Movement Service (GVMS) if the underlying export declarations (DUCRs) have received customs clearance, making it possible for uncleared goods to be exported.

From 1st August 2022, HMRC required all transit movements departing from an office of departure to present evidence of customs clearance to Border Force before they printed out the Transit Accompanying Document (TAD). However, authorised consignors could continue to enter a Transit Reference (TAD MRN) in their GMR) in GVMS when goods are exported via a transit process

In light of ongoing export compliance concerns, we are restricting the further usage of the TAD MRN. From 1 August 2023 as an Authorised Consignor (ACC), you will no longer be able to input a TAD Movement Reference Number (MRN) in a Goods Movement Reference (GMR) for an outbound transit movement leaving from the UK, including for goods being exported via Arrived Export locations, unless you are an ACC who also holds one of the following authorisations and are moving the goods in accordance with those authorisations:

  • Customs Supervised Export (CSE),

  • Designated Export Places (DEPs),

  • Internal Temporary Storage facilities (ITSFs), or

  • Export Memorandum of Understanding (MoU).

Hence, if you do not hold the authorisations listed above, you will be required to input all the DUCRs from your Transit declaration into your GMR from the 1 August 2023.

Important points and questions to note:

If you are an ACC without the additional 4 authorisations. .From 1 August, you will need to follow the processes below:

  • Include all Declaration Unique Consignment References (DUCRs) in a GMR

If you use an exporter or customs agent, you will now need to:

  • provide all the DUCRs to the person or business transporting your goods to include in the GMR.

  • make sure the Permission to Progress notices (P2Ps) have been received for the whole consignment

You must instruct the person or business transporting the goods to:

  • add all the DUCRs to the GMR – this is a legal requirement

  • take the goods to an Inland Border Facility (IBF) or a port’s designated customs facility if it is selected for an inspection. They will need to inform the staff at the site that the goods have been selected for an inspection.

If you are an ACC that has one or more of these four authorisations you can continue to use the TAD MRN to input into GVMS for outbound transit movements which means there is no change to your current business practices.

Why is it important to know this information?

  • If you do not make the change where required your goods may not be allowed to board the means of transport you intend for them to leave GB.

What if you need to make IT changes which means you will not be ready to input all the DUCRs into GVMS by the 1 August?

  • If there are IT reasons why you cannot meet the 1 August implementation date then you can write to the transit policy team in HMRC to request an extension, explaining why one is needed and what changes need to be made to your IT systems.

You will need to contact us by 20 July by sending your request to including “GVMS Input Requirements” in the subject line, to give us time to consider your request and write back to you before the 1 August.

Here to help. For more information go to:

If you still have a question about anything mentioned, please call our Customs and International Trade helpline on 0300 322 9434 and choose option 5. The helpline is available from 8am to 10pm Monday to Friday, and 8am to 4pm at weekends.
