A Safety & Security Declaration (SSD) or Entry Summary Declaration (ENS) is used by border authorities to analyse the potential risk caused to their territory by goods crossing their border. It is not about the duties and taxes.

To ensure flexibility when moving goods out of Great Britain via the Port of Dover or Eurotunnel there is a dual Freight Location Code (FLC) that should be used. This will help to avoid errors within the Goods Movement Reference (GMR).

For example: If the export declaration is created using Dover’s FLC but the driver then travels through Eurotunnel using a GMR with the Eurotunnel FLC, it will contain errors.

If the driver checks-in without correcting the errors, the GMR will be invalid, and the driver will be turned away until these errors are corrected.

Hauliers, drivers, or logistics companies must -

  • ensure your supply chain and, in particular, the trader, intermediary or declarant, know which border location you will be leaving from
  • make sure you check that they have used the dual FLC if you’re exiting via Dover or Eurotunnel.
  • make sure you have a process in place to contact the declarant, in case of an error within the GMR so they can correct the declaration.

Traders, exporters, intermediaries, or customs agents must -

  • ensure you know which border location your haulier, driver or logistics company will be using to exit Great Britain with your goods
  • use the dual FLC if your goods are leaving via Dover or Eurotunnel.

If there’s a chance the driver may change their routing after the declarations have been created, we suggest using the dual FLC for Dover/Eurotunnel to avoid any potential errors or delays.
