Hauliers moving freight between France and the UK via the Smart Border are approaching a hard deadline. French Customs has confirmed that from 20 April 2026, the presentation of an ELO (Obligatory Logistics Envelope) will be required for all transport units crossing the Smart Border with the United Kingdom.
French Customs says any transport unit using the Smart Border with the UK must present an ELO at check-in from that date. A vehicle without one may be refused boarding by the ferry or shuttle operator or, if allowed to board, may not have its customs formalities processed during the crossing.

The ELO is designed to group all key border references for a movement into a single barcode. French Customs says it is intended to simplify, secure and streamline Smart Border crossings for roll-on/roll-off traffic, whether accompanied or unaccompanied. The system covers imports, exports and transits, and the rule applies to all trucks, whether loaded or empty. Customs guidance is explicit on one more point: one truck equals one ELO.
Who needs to do what before the crossing?
From 20 April, the requirement applies to all trucks using the France-UK Smart Border, including empty vehicles. In practice, that means operators using the main Smart Border corridors — notably Calais, Dunkirk and the Channel Tunnel — need to make sure the ELO is created before the vehicle reaches check-in.
The practical sequence is straightforward, but it leaves little room for error. The operator must first secure the ICS2 safety and security filing, then make sure the relevant ENS MRN is available, and then create the ELO, which must include the ENS MRN reference. Once the ELO is created, a barcode is generated. That barcode then becomes the key document presented at check-in.
At the ferry terminal or Channel Tunnel terminal, the ELO barcode is scanned and paired with the crossing. The Smart Border system then determines the vehicle’s routing, including whether it can continue or is directed to customs controls.
To put it short: before the truck reaches the terminal, the chain must already be complete — ENS filed, MRN available, ELO created, barcode ready. If one link is missing, the truck can still arrive at the crossing but may not be able to proceed normally. This is an inference drawn from the official requirement to present the ELO at check-in and the described processing sequence.
Access to the system is already open
French Customs says the ELO application has been available through a personal douane.gouv.fr account since 28 April 2025. Operators who do not yet have an account must create one first, then search for the ELO application within the portal. Customs also says no prior registration is needed beyond having that personal account.
