Please see the HMRC message below:

From Tuesday 6th December 2022 HMRC is introducing a service enhancement which will enable you to upload up to 2500 Declaration Unique Consignments References (DUCRs) by uploading a file into each GMR via the UI, as opposed to the current process in which they are added individually.

Your file must:

• be in Comma-Separated Values (CSV) format

• have one DUCR per row

• use column 1 for DUCR reference

• use column 2 for Part IDs if your consignment is split.

The upload will be a simple copy and paste function from Haulier systems to a CSV file provided via the Web UI which, when submitted, will upload those DUCRs to the GMR.

The Web UI will provide on screen upload instructions. A reminder of this information will be set out on screen when you make declarations.
