And in everyone's opinion,
it was a succes

Not to forget Denis Redon’s grand finale with his customary “surprise report” which alone constituted a highlight of the conference that all the participants would not miss for the world. For my part, through the forums and workshops, I found myself challenged by a certain number of points that I wish to submit to your wisdom.




First of all, the European Committee of the Wise and its inventory, followed by proposals for improvement. The idea of capturing data directly from the commercial source is not new, contrary to what has been said. This has been a constant temptation for administrations since computerisation first appeared. What is new is to affirm peremptorily that this will be the rule for tomorrow. I think there is still a long way to go before achieving this and the path there is strewn with certain legal and technological pitfalls. Would such an organisation mean that data generated by an operator on the other side of the planet would be imposed ipso facto in the country of destination of the goods, without any control on the part of the consignee? Does this mean that the administration will be able to and will assume the determination of duties and taxes, along with the amount to be collected? This is no longer an evolution, but a revolution! if only with regards to the “self-assessment” mechanism provided for in the CDU.



provisions are applied properly throughout the European Union. A kind of “police of the police” that would sanction the defaulting Member States in order to ensure uniformity in the treatment of customs aspects across the union territory. Such a project, in addition to adding yet another level to the European rocket, only highlights the distortions in treatment associated with customs and economic competition between the Member States. The question arises of the powers that would be granted to the agency to carry our such a mission…

The aspect of digitalisation was also the subject of some astonishment because in any case, companies progress in this area with leaden feet. It is only under a certain duress that they are gradually evolving towards this way of organising their activities. Despite considerable work carried out to achieve end-to-end electronic transmission, we are still far from the mark.

And it is not without having ourselves contributed to European projects such as CORE and SELIS.

But it is clear that only administrative obligation is likely to force companies to advance in this area. An example is the future electronic invoicing requirement planned in the EU and soon to be compulsory in France. It is no longer a question of creating a PDF, but of constituting a set of data elements in an electronic message equivalent to an invoice. Will this finally trigger the long-awaited click?



It is also worth noting the new ICS2 organisational schema which aims to allow multiple stakeholders to complete the data set required prior to arrival of goods into the EU. I still can’t project myself onto the ground. The question is who has what when. All orchestrated under the responsibility of the international carrier. Seller, freight forwarder, carrier, consignee, each one has a certain number of data elements. But who will operate their transmission in the form of a message to the EU? How many complementary messages will it be necessary to link to obtain all the data required?  It’s going to be essential for this little group of supply chain players to organise itself… But I was stunned to learn that despite creating a centralised European platform, risk analysis is still handled nationally by each Member State. It really seems that the concept of the European Union is having a hard time establishing itself! There is no doubt that differences will exist and that these will eventually lead to the diversion of traffic to less demanding states. The expression of “states within the state” takes on its full dimension.

But the next conferences organised between now and 2030 will perhaps bring some clarifications on these points.

CUSTOMS: The power of artificial intelligence in document digitalisation


The power of artificial intelligence in document digitalisation

CONEX is launching its new OCR via conex™ module which, thanks to artificial intelligence, identifies in documents the data elements which will be useful for customs declarations, digitalises and analyses them before formatting them for direct integration into its customs clearance solutions, precisely where declarants need them.

By developing this new application in its customs software suite, CONEX saves operators from the time-consuming and tedious work of manual data entry. The relevant data elements are automatically extracted on the fly from international trade-related workflow documents, thus accelerating and securing all customs processing.

Supporting customs services in their technical development

The application is self-learning. Combined with the competence of the customs operator, it is enriched to deploy its full capacity after only a few documents processed by the declarants.

It has the ability to adapt to all types of documents, invoices, packing lists, etc. and speeds up and secures all data entry into customs declarant tools without the risk of error. By reducing the task of data entry upstream, the CONEX platform enables declarants to become more productive and to improve the safety and comfort of their work.

A number of customers have already adopted the module. They have found real opportunities for considerable gains in productivity when ramping up their customs processing.

“The return on investment, the ease of deployment and the security of customs processes are all decisive arguments for organisations. This new module takes its place within a whole series of changes to our customs declaration processing offering, thanks to Blockchain and Artificial Intelligence”, concludes Bertrand GRUSON, Managing Director at CONEX.

DELTA IE – H1 B1 DECLARATION, the new dress code for your customs data

Since its implementation in 2016, the Union Customs Code (UCC) has had many changes in store for us with regards to the overhaul of customs IT systems. For almost 40 years CONEX has been working to facilitate European customs processes and to harmonise customs data formats… DELTA IE (I for Import and E for Export) will gradually replace DELTA G and X. DELTA IE is just an additional step for which we are prepared in our objective of serving the best interests of our customers.


Those familiar with the current customs declaration will have to abandon the reference to the SAD boxes and give way to a new sequencing of +/- 80 data elements through the H1 import customs declaration and the B1 export customs declaration.


New codifications, a new organisation but the REAL change is hidden in the declarative message. And trust us, we know how to do that!
The structure of the electronic message of the H1 declaration will be perfectly respected in our customs via conex™ software.


  • No additional cost!
    The evolution towards DELTA IE is no exception to the rule that we set for ourselves at CONEX... taking charge of customs regulatory changes to guarantee the sustainability of your investment without surprises!
  • work habits do not change.
  • Everyone keeps their usual environmentDELTA IEdoes not mean a new version of the software, rather an application update.

DELTA IE IMPORT 2023 September 2023: Start of the transition period with the aim of making the change on 1st December 2023. 31/12/2023: Deadline for changeover Cohabitation: short period with DELTA G Import and DELTA I DELTA IE IMPORT 2023

At the end of April 2023, Customs announced the postponement of the start of the DELTA I/E Import experimentation phase.

On May 24, the DGDDI announced on its website that the revised timetable for the implementation of the DELTA I/E import component will be made available to operators by summer 2023.

cp-Conex_Bollore Transports & Logistics adopts Conex’s ZEN solutionBolloré Transport & Logistics adopts Conex’s ZEN solution and transforms its working relationship with its customers

At Bolloré Transport & Logistics, 275 metropolitan declarants are employed to process customs and security declarations. Little by little, the increase in administrative processing brought about by Brexit has prompted customer collaboration work to be further digitalised: the exchange of information is now organised around a documentary platform which receives and stores all the information exchanged, makes it possible to visualise processing progress, gives alerts in the event of hot spots, and produces periodic reports.


Towards a complete digitalisation of shared work

On post-Brexit 1st January 2021, the Bolloré Logistics Customs department suggested that its customer NESTLE work on the Conex ZEN platform. This secure digital workspace receives, centralises and archives documents and correspondence between the registered customs representative-freight forwarder and its customers, making it possible to optimise the completion of customs formalities for import / export operations. ZEN via conex™, which organises exchanges in a methodical way, quickly proved its worth and other Bolloré customers followed suit and joined forces with the collaboration tool…

“The Nestlé Group was the first customer to switch to this new work organisation, first, 10 declarants used it for the exchanges with their correspondents in 7 or 8 factories. Today, 30 declarants are connected to the tool for 6 customers and the movement is speeding up, with 100 declarants and about 15 customers planned to make the move in the short term. In the deployment stage, 2 hours are enough to train new users,” explains Jean-François Ledun, Customs Director at Bolloré Logistics.

Greater processing visibility and speed

ZEN via conex™ offers users a timesaving, collaborative workspace. Through an IT link, ZEN automatically assigns data to the corresponding declaration fields in CUSTOMS via conex™, the customs declaration software. The mandatory documents are thus progressively pre-filled, the only human intervention being for the purposes of verification.

ZEN provides traceability of exchanges between Bolloré and its customers at this pre-declaration stage. The customer gradually uploads the necessary documents to the declarants, ZEN intelligently organises all the data flows while the customer can follow closely throughout the life of the declarative file. An alert notifies the declarant concerned of any action on the platform, and he/she can then access the transmitted documents. The exchanges in the pre-declaration phase are tracked and the platform centralises documents and information which in the past arrived via a variety of methods such as email, telephone, drive etc, depending on each person’s habits.

Jean-François Ledun explains: “We know, file by file, where we are at any given moment, thanks to a condensed overview; if data is missing to clear an entry, we see it immediately and can take care of it as a priority.”

When the declarant sends the declaration to the customs administration, the processing workflow is tracked, and the customer and the declarant are kept informed of progress in real time.

Report templates are customisable according to customer criteria, so no more wasted time searching for data to compile reports. Performance indicators, such as the average processing time per declaration, are calculated automatically, and financial management data are summarised (amounts of customs duties, VAT, etc.).

“As a registered customs representative, and therefore a service provider, we must periodically provide reports to our customers. In some cases, it could take man-days to compile the information and present the renderings to the customer; with ZEN, creating reports is made easy, with preformatted templates,” emphasises Jean-François Ledun.

Finally, document and declaration archiving in ZEN via conex™ is another advantage: it is operated at the request of a customer for up to 10 years for all declarations and documents. The opposability of the archiving is reinforced by the use of Blockchain technology which will certify and timestamp each document and action making up the file.

About ZEN via conex™: ZEN via conex™ is a collaborative platform for exchanging, centralising, tracking and archiving data, documents and electronic messages. The customer can thus log all the movement of entries throughout the import/export process, from the pre-declarative phase right through to filing. Multiple actors – customers, partners, collaborators, importers, exporters, carriers … -, intervene in turn to enrich the declaration, in a collaborative workflow.

Transports Mesguen chose Conex solutions to create a post-Brexit Customs activity


Since Brexit became a reality, Transports Mesguen, an SME located at the northern tip of Finistère, has been using Conex solutions for clearing goods en route or arriving from the United Kingdom. A highly strategic step in the Supply Chain, especially for food, live and ultra-fresh products.

A strategic challenge

To adapt to Brexit, the SME of 50 million euros at the head of a national fleet of 150 lorries created a whole new 6-declarant-strong department from scratch at the company headquarters in Saint-Pol-de-Léon. This new Customs department has been equipped and trained in the new regulatory obligations related to transporting goods to and from Great Britain, and in Conex's specialised software: the France and United Kingdom Customs solution, - Management of customs procedures on both sides of the Channel - and the EU ICS and S&S GB modules for processing security declarations.

This new declaration activity has become a profit justifyand a competitive asset for Transports Mesguen. But in reality, the project to internalize customs and security declarations was also strategic for the company: the United Kingdom's share of turnover is 25% of the 50-million-euro total. However, a significant part of the movements concern ultra-fresh food products, vegetables, poultry and seafood products. In this Supply Chain which delivers products on D+1 most of the time, outsourcing declarations to a third party could have penalised its reactivity.

Philip Gac, general manager in charge of financial and HR for the company, initiator of the project, explains:

“Entrusting customs declarations to a third party is possible on paper, but in practice, it multiplies the number intermediaries, communication difficulties, and the risk of delays…. In the world of ultra-fresh transport, when the goods must be delivered on D+1 (we are talking about live crustaceans, in particular), the Supply Chain cannot suffer the slightest delay, otherwise the goods may be lost! Above all, we did not want our lorries to be blocked at the borders upon arrival in England or France!”

It’s ancient history

Transports Mesguen has been developing transport services between the continent and the United Kingdom since the 1960s. But over the past thirty years, since 1993 with the United Kingdom’s entry into the European Union, import/export formalities had disappeared.

Until we heard talk of Brexit. As a result, on January 1st, 2021, a department resurrected the service on brand new foundations: new regulations, new process, new team, new software... The context of political indecision and regulatory uncertainties surrounding the implementation of Brexit forced the SME to adapt, a push on the brakes then rapid acceleration, both in building up skills for its staff and for the implementation of software.

Conex has supported this Brexit project since the start, two years ago, and it is with the same determination that the two companies have worked on it, the editor adapting its software offering throughout the political negotiations and training the Transport Mesguen personnel.

Les Transports Mesguen ont retenu les solutions de Conex pour créer une activité Douane post-Brexit

Collaboration with Conex

March 2019, the decision to commit to the organisation of an internal customs clearance service for movements to and from the United Kingdom is taken. They will need teams and software and Philip Gac, who has taken the initiative to run the project, approaches Conex: “Conex is the market leader, its reliability has been confirmed to me by several freight forwarders that I know. The overall project already included enough uncertainties, I wanted security with regard to the IT solution to be chosen. And the first contacts with the teams went well from the start. In addition, Conex had the clear advantage of offering the CUSTOMS via conex™ software which is connected to UK Customs (CHIEF, CDS). Thus, the information about the goods that we transport for our customers is entered and/or interfaced only once, either on the French side or on the UK side to be sent to customs on both sides of the Channel; they appear mirrored in the Conex solution on either side of the border without additional work.”

Philip Gac estimates the need for 6 or 7 people for his customs team; but hiring, while Brexit is not yet a certainty, is a challenge. He then offered all the administrative staff the possibility of joining the future Customs department, which clearly meant training his staff in the new profession of customs declarant and, therefore, in the Conex tools. 8 people are on the starting blocks, this is enough to cover the needs of a service open from 7 a.m. to 10 p.m. 7 days a week. 3 people, including himself, start training in the spring of 2019, and will in turn train their future colleagues in the new department.

In parallel with the training, IT work is carried out to integrate the Conex tools into Mesguen's information system: this involves limiting manual entries by directly injecting the data already present in Mesguen's accounting and transactional tools into the heart of Conex interfaces. Philip Gac added: “This integration of Conex into our IT system went very well, and for our team it was really a condition for managing large volumes quickly and without the risk of error!

A thwarted launch schedule

Transports Mesguen is ready for Brexit and customs declarations. Except tha,t as we know, nothing is done on time, that one Brexit postponement follows another and that for the SME, they must remain on alert, careful not to forget anything that they had just learned but could not yet apply. So, they continue to train on fictitious datasets for two hours a week, while continuing their usual work as if nothing had happened...

Finally, September 2020, the approach of D-Day again becomes credible and imminent. They are back in pre-project mode: in September, two employees are seconded to the customs department on a half-time basis, then full-time in October. In mid-November, training sessions for processing customs declarations resume every day for all future declarants. The horizon line is getting closer. And on January 1st, 2021, the very first customs clearance declaration in the new post-Brexit customs system is completed successfully. “It was a lorryload of Scottish crabs that was to go to Spain. Live produce, of great value, a cargo of at least 100,000 euros to be processed urgently of course, which Transports Mesguen inherited almost at the very last minute.”

The first weeks will be busy... Customers have not anticipated the new customs complexity, and are discovering on the job that Brexit has changed handling arrangements, that lorries are no longer allowed to cross the borders of England if customs formalities have not been completely cleared… Not to mention that live produce must also obtain health certificates.

Mesguen and its teams are in charge, recovering missing invoices, making dozens of calls to obtain missing information urgently, inputting and clearing customs with all their might... The first week will remain memorable, working from 8 a.m. to 2 am… In the end, the service is fully operational, Mesguen has set up a new activity based on Conex software, and developed its turnover, its teams have proven their ability to take on a memorable challenge and deliver!

About Transports Mesguen

For 70 years, the company has specialised in the road transport of foodstuffs (fruit, vegetables, seafood, etc.), fresh or frozen. It has a fleet of 85 refrigerated semi-trailer lorries. Among other things, Transports Mesguen ensures the transport of industrial products, with more than 75 semi-trailers. It also has several temperature-controlled storage warehouses.
