Great Britain - Customs Declaration Service (CDS) & MAMAEDO

Scheduled for Jul 4, 21:00 CEST - Jul 5, 04:00 CEST

Scheduled

Due to scheduled maintenance, the Customs Declaration Service (CDS) and the Make and Manage an Export Declaration Online (MAMAEDO) service will be unavailable to all users from Saturday 4 July 20:00 until Sunday 5 July 02:30 (BST).
Declarations should not be submitted during the outage. Creating, updating, or embarking a goods movement reference (GMR) may be affected, and only goods with pre-lodged declarations attached to a GMR will be allowed to move using the Goods Vehicle Movement Service (GVMS). For import movements using GVMS, check the declaration status and arrive your goods where needed. If moving consignments containing controlled goods with pre-lodged declarations, attend port inspection facilities or inland border facilities for goods to be inspected and released. Exports should have Permission to Progress (P2P) before travelling.
