July 2024 — NCTS Phase 5: issues affecting some Office of Transit and Office of Destination codes

Updated 5 December 2024

HMRC are aware of an issue relating to some Office of Transit and Office of Destination codes affecting transit movements raised in the New Computerised Transit System (NCTS) Phase 5.

The NCTS Phase 5 was implemented on:

  • 28 June 2024 in Northern Ireland (XI)
  • 1 July 2024 in Great Britain (GB)

What has happened

Some declarations are being rejected and stating a G0034 error when certain Offices of Transit and Offices of Destination codes are used.

We have identified that this is in direct relation to system rules where the Automated Export System (AES) is in use in other national administrations, but not in GB or XI.

What are we doing

We are working with the Directorate-General Taxation and Customs Union (DG TAXUD), who administer the Common Transit Convention (CTC), to understand the issue and find a resolution for our GB and XI systems.

What you need to do

If you receive the IE056 rejection message with error G0034 after submitting your IE015 transit declaration with the relevant Office of Transit and Office of Destination codes, you should use the following workaround.

  1. In the goods item — previous document type field do not use N830 (export declaration) as the type of previous document.

  2. Use an different code, such as NMRN (Notification Movement Reference Number), in the previous document type field.

  3. Continue to provide the Export Movement Reference Number (MRN) in the reference number field within the same ‘previous document’ data group.

If it is not possible to provide the Export MRN in the previous document reference number field, you should provide it in the supporting document space and use the supporting document type ‘NZZZ’ (other).

We will notify you when a more permanent resolution has been identified.

We thank you for your patience and apologise for any inconvenience this may cause.
