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.



Anyone who is authorized by their business to make a customs declaration can do this, however it is important to note that only businesses based in a country are able to lodge a declaration there.

For example, a UK company cannot submit a declaration into French Customs (unless they have a French subsidiary or a French entity who is willing to act as a legal representative).
