If you’re moving goods between the UK and France, you’ve probably come across the term ELO—but what exactly is it, and why does it matter?
Let’s break it down in a simple and more practical way.
Since the 28th April 2025, an Enveloppe Logistique Obligatoire (ELO) has been available for use on GB to FR and FR to GB shipments.
An ELO is now a mandatory requirement from 20th April 2026.
What is the ELO?
The ELO (Enveloppe Logistique Obligatoire) is a mandatory digital envelope required by French Customs for vehicle movements between Great Britain and France.
Think of it as France’s version of the UK’s GMR (Goods Movement Reference). It acts as a single reference code that pulls together all the necessary customs and safety documents for a vehicle into one place. A GMR is still required as the ELO does not replace UK customs processes.
Instead of juggling multiple references, the ELO neatly bundles everything into one digital “envelope,” including:
- Import and export MRNs
- Transit MRNs
- ENS filings (ICS2)
- SPS and other regulatory control documents
Who is responsible for creating ELO?
The haulier is responsible for creating the ELO. This must be created before departure with all shipment data being fully complete and accurate.
How Does the ELO Work?
The ELO is closely linked with ICS2 (Import Control System 2), meaning that at least one ENS declaration is required per ELO. It also works alongside systems like SI Brexit to streamline the customs process.
Here’s how it plays out in real-world operations:
- At Check-In
When arriving at the port, the driver presents both their GMR and ELO barcode.
This barcode contains all the relevant customs information for the load—fully consolidated and ready for inspection.
- During the Crossing
While the vehicle is in transit, authorities carry out a risk analysis using the submitted data.
Drivers can monitor progress via onboard display screens, which show the status of their vehicle.
- Upon Arrival
Once the ferry or shuttle arrives and the driver disembarks, the vehicle is directed based on the outcome of the risk analysis:
- Green Lane → No further checks required. The vehicle can leave the port and continue its journey.
- Orange Lane → Additional checks may be needed, or the analysis is still ongoing. The driver may need to report to the customs office at the first point of entry.
Why the ELO Matters
The ELO simplifies what used to be a complex, fragmented process. By consolidating all documentation into a single reference, it helps:
- Reduce delays at ports
- Minimise administrative errors
- Improve overall efficiency in cross-border logistics
Making Port Passes Easier
Less time spent dealing with customs paperwork means more time focusing on what really matters—growing your business.
Solutions like digital logistics envelopes and streamlined port pass creation can save both time and money, helping operators move goods faster and with greater confidence.
In a world where efficiency is everything, tools like the ELO are transforming cross-border transport—making the journey smoother for drivers, businesses, and customs authorities alike.
