NCTS5 Final State Rules were implemented on January 21st this year, and all CTC member states went live with NCTS5 simultaneously.   

An issue has been raised regarding Document Code N830, where some member states are misaligned with implementing the document code into working practice. 

HMRC has advised that the N830 code used for Previous Document/Type should only be used at the House Consignment level, not at the Consignment Item level, as some member states have implemented. This aligns with guidance in the code list CL214, which specifies acceptable document codes.   

Where other CTC member states have implemented the N830 code at the Consignment Item level, an error message is generated, and messages sent to NCTS5 GB are rejected, preventing the movement from being closed at the Office of Destination. This will also impact the IE050 (Anticipated Transit Record) and/or IE115 (Anticipated Transit Record Response) messages at the Office of Transit. 

While HMRC work together with CTC member states to iron out any misalignment with NCTS5 administration, they ask that GB transit users contact their counterparts in other CTC countries and confirm that the N830 Previous Document/Type code N830 is submitted at the House Consignment level only 

If Transit users are having issues attempting to validate a transit MRN in GVMS, the ‘SAD’ option may need to be used in the GMR. Note that this will automatically hold the goods to allow Border Force to validate them at the Office of Transit and/or Office of Destination.
