What Is ELO and ICS2? A Plain-English Guide to France's New RoRo Border Requirement

 




What Is ELO and ICS2? A Plain-English Guide to France's New RoRo Border Requirement

 

If your business moves goods by road between the United Kingdom and France — or you work with hauliers, freight forwarders, or logistics providers who do — you may have started hearing about two terms: ELO and ICS2. From 20 April 2026, both of these become directly relevant to whether trucks can cross the French border without being diverted for inspection. This article explains what they are, how they connect, and what businesses need to do.

What Is the ELO?

ELO stands for Obligatory Logistics Envelope — in French, Enveloppe Logistique Obligatoire. It is a digital barcode system introduced by French Customs as part of the Smart Border regime that governs truck movements between France and the United Kingdom since Brexit. The idea behind it is straightforward: instead of requiring different parties at the border to check different customs documents separately, the ELO brings all the relevant customs declaration references for a given truck together under a single barcode that can be scanned once.

From 20 April 2026, that barcode is not optional. Every truck crossing the French Smart Border — whether it is loaded or empty, moving from France to the UK or from the UK to France — must have a valid ELO barcode to present at the crossing infrastructure. Trucks that arrive without one will be directed to the orange lane for physical customs inspection, causing delays.

The ELO is created on the French Customs website at douane.gouv.fr. It is free to access. Whoever in the logistics chain has access to all the relevant customs declaration references for a crossing — the freight forwarder, the transport manager, or the customs agent — creates the ELO, enters all the required declaration MRNs, closes it, and prints the barcode PDF for the driver to carry.

What Is ICS2 and Why Is It Part of the ELO?

ICS2 is the EU's second-generation Import Control System — a safety and security declaration system that requires advance information about goods entering the EU to be filed before they are loaded onto the vehicle. This advance filing is called an Entry Summary Declaration, or ENS. It tells EU customs authorities what is on the truck, who it is coming from, where it is going, and what route it is taking. EU customs use this information to assess safety and security risk before the goods arrive.

For truck movements from the United Kingdom into France, an ENS must be filed through ICS2 before the goods are loaded. When the ENS is submitted and accepted by the ICS2 system, a Movement Reference Number — MRN — is generated. That MRN is the proof that the safety and security declaration has been received and is in good standing.

The connection to ELO is direct: for a loaded truck moving from the UK into France, the ICS2 ENS MRN must be included in the ELO. Without it, the ELO cannot be completed and closed, the barcode cannot be generated, and the truck cannot present a valid ELO at the border. In practical terms, the ICS2 ENS filing is the step that must happen first, before the ELO can be assembled.

How Customs Declarations UK Makes ICS2 ENS Filing Simple

 

HOW CUSTOMS DECLARATIONS UK HELPS

The Simplest Way to File Your ICS2 ENS and Get Your MRN

Customs Declarations UK is a UK-based cloud platform that provides businesses, freight forwarders, hauliers, and customs agents with a simple, guided way to file ICS2 Entry Summary Declarations directly to the EU's ICS2 system. The platform is designed for users of all experience levels — you do not need to be a customs expert to use it. Step-by-step wizards guide you through every piece of information required for an ICS2 ENS filing: who is sending the goods, who is receiving them, what the goods are, how they are being transported, and what route they are taking.

Once the declaration is submitted and accepted by ICS2, the platform generates the MRN immediately. That MRN is then ready to be entered into your ELO on douane.gouv.fr, completing the chain. Real-time validation checks your data before submission, which means errors are caught before they cause rejections and delays. For businesses with regular UK-France lanes, the clone feature lets you save a shipment profile and reuse it, so you are not re-entering the same information every time. All filings are stored securely and can be retrieved for compliance purposes at any time. Customs Declarations UK also handles UK CDS import and export declarations, meaning the platform supports both sides of the customs chain for UK-EU trade.

▸  Guided ICS2 ENS Wizard:  Plain-English workflow covering all required safety and security data elements — consignor, consignee, commodity, transport, and routing.

▸  Instant MRN on Acceptance:  The ICS2 MRN is generated immediately, ready to be inserted into the ELO on douane.gouv.fr before departure.

▸  Real-Time Validation:  Data errors are flagged before submission, reducing rejection risk and ensuring MRNs are available when you need them.

▸  Clone for Repeat Lanes:  Set up regular shipment profiles once and reuse them — cutting manual re-entry and the risk of inconsistent data.

Who Needs to Take Action Before 20 April 2026?

The answer is: anyone in the UK-France road freight chain who is not yet fully prepared. Hauliers need to confirm that whoever manages their customs documentation is filing ICS2 ENS declarations and can produce an ELO before trucks depart. Freight forwarders need to ensure their ENS filing workflow runs through ICS2 and that MRNs are available in time for ELO creation. UK exporters need to check with their logistics partners that all of this is in place for their shipments. Customs agents need to confirm that their filing systems are ICS2-compatible and their clients are being covered.

The ELO application has been available voluntarily on douane.gouv.fr since April 2025. The mandatory date of 20 April 2026 has been confirmed by French Customs and will not change. The time to prepare is now, not on or after that date.
