French Customs authorities have revised the dates they will be switching off their national transit management system (Delta-T). This outage will now take place from Friday 22 November at 18:00 until Monday 25 November at 10:00 (Central European Time) to complete the changeover from Phase 4 to Phase 5.
Full details of the system downtime are set out in the link attached.
The French Delta-T system will not be operating during the system downtime. All goods moving under Transit from the UK will have to stop upon arrival into France for the Office of Transit function to be completed manually by French customs officers.
French authorities will be mobilising all their services during this downtime to offer the smoothest possible flow of freight traffic.
This downtime does not affect GB systems and no change in process is required by UK operators who will also continue to complete the SI BREXIT system.
Please note: This is not a HMRC outage and HMRC are unable to respond to any queries on the French system downtime.
