Saturday 28 September 2024 21:30 to 03:30 Sunday 29 September 2024

Creating, updating, or embarking a goods movement reference (GMR) that are linked to CDS could be affected during the times listed.  For guidance on GVMS please refer to the GVMS service availability and issues page.

Import movements using GVMS during the outage – Members should check the declaration status and arrive where necessary.

If moving consignments containing controlled goods with pre-lodged declarations, follow published guidance and attend port inspection facilities / Inland Border Facilities for goods to be inspected and released.

If exporting goods from locations which require an arrived export, submit your declaration and obtain permission to progress (P2P) before the outage. If exporting goods from any other location, you will need to arrive at the border location and obtain P2P prior to the outage or wait until after the outage to move your goods.

The Customs Declaration Service (CDS) will be unavailable from:

21:30 on Saturday 28 September 2024 to 03:30 on Sunday 29 September 2024.

Declarations submitted during this time will be processed when the service becomes available.

CDS will be updated to version 4.6.0. As part of the update some of the functionalities will be affected. To assist the trade, HMRC has issued a document which provides clarification on the implemented changes and also lists specific declaration completion instructions.

In order to avoid declaration rejections for shipments arriving on or after the 28th of September, all declarations should be pre-lodged according to the shared guidance.
