Understanding the French ELO requirements: What businesses moving goods through France need to know.

What is ELO?

ELO is a French Customs digital envelope that groups the information needed for a Smart Border crossing under one barcode.

It brings together the relevant information linked to the goods, safety and security requirements, and customs formalities for the movement. Where required, safety and security data must be included in line with EU requirements.

For operators, this means fewer manual interventions, more predictable crossings, and greater control over border risk.

When did ELO become mandatory?

ELO became mandatory on 20 April 2026.

The system has been available via douane.gouv.fr since 28 April 2025, following a transition period that gave operators time to adapt.

The original mandatory date of 1 September 2025 was postponed. French Customs has now confirmed that the requirement applies from 20 April 2026.

Who needs an ELO?

An ELO is required for transport units using the French Smart Border with the UK.

This includes:

• Loaded trucks
• Empty trucks
• Accompanied RoRo traffic
• Unaccompanied RoRo traffic
• Import, export and transit flows

Only one ELO should be created per transport unit.

What happens if there is no ELO?

From 20 April 2026, a transport unit without an ELO may be refused boarding by the ferry or shuttle operator.

If the unit is allowed to board, customs formalities may not be processed during the crossing. This creates a clear risk of delay, manual intervention and disruption at the border.

What businesses should do now

Businesses moving goods between the UK and France should make sure that ELO is embedded into their operational process.

Actions include:

• Confirm who creates the ELO for each movement
• Make sure the responsible party has access to douane.gouv.fr
• Check that all customs references are available before check-in
• Confirm whether ICS2 ENS data is required for the movement
• Share the ELO barcode with the driver, haulier or transport provider in time
• Avoid relying on outdated envelope processes

Good coordination is essential. The ELO may depend on data from several parties, including the exporter, importer, carrier, freight forwarder and customs representative.

Why ELO matters

ELO is part of the continued digitalisation of border processes between the UK and EU.

For businesses, the requirement is not only about compliance. It is about protecting the flow of goods, reducing avoidable delays and keeping border processes predictable.

The businesses best prepared will be those with clear ownership, accurate data and reliable communication across their supply chain.
