UK Border Force team at Belfast Harbour customs will process the transit declaration and return an MRN and TAD (Transit Accompanying Document) to TransitNet.

Additional Information

It is necessary to register the transit MRN in GVMS for entry to Great Britain to ensure that the office of transit function is performed on entrance to Great Britain. Registration in GVMS can be performed by SGS on behalf of our clients.

For transits which will re-enter the EU via France, it is the responsibility of the transporter to organise the mandatory ENS declaration. For transit declarations submitted via TransitNet, the ENS declaration is generated automatically and sent to the French Import Control System. The pairing of the ENS MRN with the vehicle registration numbers is done automatically by the French Smart Border System (SI Brexit).

Closing a T2 transit declaration

For transits with goods which are destined for destinations within the EU, SGS recommend closing the T2 in our partners location, the Calais Truckstop. Conveniently located in Calais, it is the perfect location to discharge a transit before continuing your journey to the destination of your goods. For trucks travelling with SPS goods, please make sure your driver has a copy of the validated CHED.
