Due to scheduled maintenance on the Customs Declaration Service (CDS), the CDS service will be unavailable to all users on Saturday 26th September 2026 from 7 PM until 8.30 AM on Sunday 27th September 2026.

Please note that this outage will be longer than usual. We encourage you to make sure you take the appropriate action as described below to minimise disruption to your business.

Declarations submitted during this timeframe will be processed at the end of the downtime.

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 – customers 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.

We apologise for any inconvenience this may cause.
