● Public sector — Customs officer

AI agent for customs officers (administrative support)

An assistant that answers traders, prepares the regulatory documentation and supports the handling of declarations — the officer keeps the inspection and the decision. A strictly administrative and documentary scope: no targeting, no surveillance, no decision about people. Hosted in France, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.

A trader asks which regime applies to goods returning after repair outside the EU. Prepare a documented reply.
Reply prepared. The case falls under the outward processing regime: the reply recalls the principle of taxing the value added by the repair, the prior authorisation required and the evidence to produce on re-importation. Dated references attached for checking.

The customs officer decidesDocumentary support, never targeting
✦ In brief

In customs, a Blue Lemon Agent agent assists officers with the administrative and documentary tasks — replies to traders (procedures, tariff classification, regimes), up-to-date regulatory documentation, checking the documentary consistency of declarations. Its scope is strictly administrative: no targeting, no surveillance, no decision about people. It runs on local inference or is hosted in France on a dedicated, isolated resource, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. The customs officer keeps the inspection and the decision. Live within a few weeks. Your public-sector staff write to it from Microsoft Teams, Slack or their email, and traders reach it on WhatsApp Business, the website chat or email — with no account to create and nothing to install. Reaching the administration from the tool people already have means less non-take-up of rights and equal access to the service. These connections are included in every plan, at no extra cost, within the number of connections your level includes.

The context

Why AI matters to customs — and why it demands guarantees

Tariff classifications, special regimes, regulations that never stop changing: customs officers answer traders every day for whom every documentary error is expensive. The data handled — trade flows, declarations — demands strict confidentiality.

! The issue

Customs officers are caught between traders who expect precise regulatory answers and documentation in permanent change (the Union Customs Code, tariff classifications, special regimes). Yet most consumer AI tools amount to entrusting declarations, trade flows and traders' data to a third party, often hosted outside Europe and subject to the Cloud Act.

Our answer

For customs data, AI is only of interest if it is sovereign, confidential and strictly bounded. Local inference or an isolated resource hosted in France, systematic human oversight, a scope limited to administrative and documentary support: no targeting, surveillance or inspection-decision function, by design and in line with the AI Act. The aim is not to replace the officer, but to give them back time from documentation and repetitive replies.

The decisive point

Protecting customs data: sovereignty & compliance

A customs unit handles sensitive commercial and declaratory data. Here is how the architecture of our agents protects it — and how its scope is strictly bounded.

Local inference

The agent can run on a machine at the unit: no data leaves the network, nothing passes through a cloud.

Hosting in France

Otherwise, a dedicated and isolated resource, hosted in France under French law — the data: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

As regards traders' data, exposure to the Cloud Act and FISA 702 is reduced by design; location alone does not guarantee immunity.

One isolated resource per department

No pooling of data: an environment strictly dedicated to your unit, guaranteeing the continuity of the public service.

Encryption & controlled access

Encryption in transit and at rest, role-based access (RBAC), strong authentication and logging.

AI Act: governed deployment

A strictly documentary scope: no targeting, no decision about people; traceability and human oversight from end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • The encryption mechanisms in transit and at rest, their components and key management are those documented for the architecture chosen.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For the most sensitive data, SecNumCloud and HDS options are available depending on your requirements. A single architecture is designed to answer both the GDPR and extraterritorial exposure. Designed for deployment in line with the GDPR and the AI Act, after the processing, roles and context-specific risks have been assessed.
Demonstration

See the agent at work

5 real situations, taken from those that come up most often. Pick one: the exchange unfolds as it would in your organisation.

A scripted demonstration. These exchanges show how the agent behaves — its sources, its refusals, what it leaves to your teams. Nothing is sent from this page, no model is queried here, and the matters named are fictional. That is precisely what we promise your data.
The behaviours shown here — monitoring, automation rules, routing and reminders — are configured with you during deployment, from your tools, your rules and your thresholds.
The architecture points named in these exchanges — location, local execution, isolation, encryption, role-based access, logging — are not a guarantee attached to the demonstration: they are those of the architecture set out in your quotation, and verified before commissioning.

The public body in this demonstration

Fictional public body

Val-Sireuil customs office — clearance and procedures management service

Sector
Customs administration — clearance, special procedures, information for traders and declarants; counter open 30 hours a week
Headcount
22 officers — 4 on trader information, 6 in the procedures management unit and 8 processing declarations; the digital agent is connected to administrative and documentary support only
Public served
610 liable companies and declarants followed, 180 of which file every week — 6,330 requests a year: 4,100 calls, 1,450 written questions, 780 messages
Scale
18,400 declarations filed a year, of which 3,600 go through the office's documentary check in batches of 24; 380 regulatory letters and 96 applications for a special procedure authorisation
Tools in place
The administration's filing applications, e-mail, the office's document base and nine years of archived written answers — the agent connects to them read-only, nothing is replaced or migrated
Who decides
The sworn customs officer decides on checks and signs; the head of the procedures unit approves answers to traders before they go out; the head of office signs the mandates
The room for improvement
38 % of traders' calls ring out beyond the 30 opening hours; a written question waits 11 days for its answer; one filed declaration in five comes back as a request for a supporting document; and 6 of the 41 sheets in the document base predate the update that amends them

At Val-Sireuil, four officers answer traders and six run the procedures while 18,400 declarations pass through each year. The data handled — invoices, contracts, companies' trade flows — is among the most sensitive a service receives, and it does not belong to that service. The agent runs locally on a machine in the office, reads the nine years of written answers without ever writing to them, scores neither company nor person, and sends nothing out without a public officer's approval. The exchanges below cover a year, from the overhaul of the document base to the review presented to management.

This public body, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real service.

Customs assistant · hosted in France
I reread your nine years of written answers over the weekend — 7,400 answers to traders, 41 sheets from your document base, 12 letter templates — and I have drawn out a finding your files were carrying without anyone having the time to see it.
The gap measured, and it commands everything else: 6 of your 41 reference sheets predate the regulatory update that amends them. The sheet on goods returning after repair outside the Union still points to the form that has since been replaced; the sheet on proofs of origin gives the address of a service that has moved. These are not drafting mistakes: they are sheets that aged while nobody had the time to reopen them.
What that costs today, across three items you can check yourself:
· Preparing a documented answer to a trader accounts for 60 % of the time a question takes48 minutes out of the 80 a written question takes from arrival to dispatch.
· Laying out a regulatory letter: 40 %, that is 24 minutes out of 60.
· The documentary check of a batch of 24 declarations: the whole of the task, done by hand today96 minutes per batch.
What I propose, and it is not a promise — it is already written: I rewrote the 6 sheets overnight, each aligned on the version in force of the official sources the office has designated, with the replaced line, the line replacing it and the date I read it, side by side.
What that would have changed over the past year, since that is the only measure that counts: the 214 answers sent last year on the basis of one of those 6 sheets would have quoted the version in force, and the 31 traders who called back to check would not have had to.
What I do with the three items once the sheets are settled: I prepare, and you keep what only you can do — check, correct and approve. Preparation drops to 10 %, 10 % and 20 %: 8 minutes, 6 minutes, 19 minutes.
The next step, and it takes twenty minutes: you reread the three most used sheets, I bring them to you tomorrow morning. The unit head settles the version and it is live that same eveningit is the service's approval that makes an answer binding towards the trader who relies on it, and it is the only act I leave to you. document-base-inventory_41-sheets-6-to-revise.pdf41 sheets reread, 6 rewritten, the update that governs each
⛓ Sourced · 9 years of the office's written answers, document base, official sources designated by the service, 6 sheets rewritten
There are four of us on trader information and I do not have half a day to spend on reference sheets. Where do I start?
With three sheets, not forty-one — and I have ranked them by the time they give you back, not alphabetically.
What the count of your 1,450 written questions from last year says:
· Special procedures for repair and processing: 412 answersa special procedure is the framework that lets goods leave, enter or stay otherwise than by simply being placed on the market: repair outside the Union, processing, storage, transit.
· Proofs of origin: 268 answers.
· Supporting documents expected with a declaration: 204 answers.
Those three sheets carried 884 of the year's 1,450 answers: three sheets out of forty-one, 61 % of what your unit writes. The other 38 can wait until autumn without changing anything to your workload.
What I bring you within those twenty minutes, and that nobody has the time to do: the three up-to-date versions, already written, the governing update alongside with its publication date, and the number of answers each would have served last year alone — 412, 268 and 204.
And what stops this work having to be redone in two years: I go through the official sources the office has designated every night, and within twenty-four hours I write the updated version of any sheet an evolution amends. Over the last twelve months, 23 evolutions affected your sheets: 17 reached them, 6 never didand those are exactly the 6 sheets I rewrote. Every reference goes out with its source and the date I read it: I never quote from memory, and that is what lets the trader check your answers for himself.
The next step I propose: that the updated version reaches you as a draft the morning after the evolution, together with the list of the year's answers that relied on the former version. Last year those 214 answers would have gone out on the version in force, and your four officers would have had nothing to catch up on. You approve the principle once, and your 41 sheets stop ageing in silence. unit-workload_where-the-time-goes.pdf6,330 requests a year, 3 sheets for 61 % of the answers
⛓ Sourced · answers counted per sheet over 9 years, official sources designated by the office, 3 rewritten versions
All of this means you read our declarations, the companies' invoices and our exchanges with them. Where does that go?
It goes nowhere. I run on local inference on a machine in the office, and nothing I read leaves your network.
Local inference means the model computes on your own machine: a company's invoice or the body of a declaration crosses no outside network to be processed. If the service would rather not run a machine, the other route is an isolated resource hosted in France, dedicated to your officeno pooling with any other service, which is the condition for the continuity of yours.
What that changes, point by point:
· Traders' commercial data trains no model, neither ours nor a third party's. What I read about a company serves that company's file and nothing else.
· I work read-only on your filing applications, and the technical account I read through has no right to writethat is firmer than a promise, because it can be verified with a single command.
· Encryption in transit and at rest, role-based accessrights follow the job: information staff do not open control files, and the reverse holds too. 5 roles for your 22 officers, and the log shows 0 out-of-role access since go-live.
· Hosting in France, under French law, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
· A complete log: who asked what, when, what I produced and who approved it.
And one thing I say myself to every trader, in the very first sentence: that I am a digital assistant of the office and not an officer. This is not an option you could switch off — the European regulation on artificial intelligence requires that anyone interacting with an AI system be informed —, and the trader may ask for an officer at any moment: I then take the request and hand it to you with the subject already noted.
The figures that sum all this up: Hosted in France, 0 item of data out of the office network across the year's 18,400 declarations, processing in the EU targeted.
What I propose: that I keep up to date the record your management and your data protection officer will ask for — hosting, data processed, retention periods, who accesses what. It is asked for once a year and takes two days to rebuild; the first version is already written and waiting for you. technical-framework_where-traders-data-lives.pdfLocal inference, read-only, processing in the EU targeted

Frequently asked questions

Your questions, our answers

Does the agent do targeting or operational inspection?
No: strictly administrative and documentary. No use for targeting, surveillance or decisions about people.
Is the data sovereign?
Yes: hosting in France under French law, an isolated resource, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity.
Does the agent carry out targeting or inspections?
No: its scope is documentary support and answering traders; no targeting or inspection-decision function.
Is it up to date with regulatory changes?
It relies on your official sources and a targeted watch; the references stay verifiable and dated.
Does the agent state that it is an artificial intelligence?
Yes, from the very first interaction, and this is not a configuration option: since 2 August 2026, Article 50(1) of the European AI Regulation requires that any person interacting with an AI system be informed, unless this is obvious. The announcement is built into the greeting, in the other party’s language, and they can ask for a human at any time.
How long does it take to deploy an agent?
A few weeks as a rule, after a free audit that identifies the most useful use case, then a phase of design, integration and testing before going live.
Do we need a technical team to run it?
No: the agent is designed, installed and operated by us. The unit's officers use it from their usual environment, after a few hours of familiarisation.
Do we have to change software?
No. The agent complements your existing applications, with no migration imposed. The integration is defined at the design stage, respecting your security rules.
Which tools can traders use to reach the agent?
The ones they already have. The agent answers on WhatsApp Business, the website chat and email: a trader has no account to create and no application to install. Exchanges stay administrative and documentary — procedures, classification, documents expected — and are never used for targeting or for tracking people. This is a lever for access to the service — WhatsApp and the telephone reach people an online form never does, which reduces the non-take-up of rights and serves equal access. Internally, your public-sector staff talk to the agent from Microsoft Teams, Slack or their email, without switching tools. Oversight runs from a web dashboard. These connectors rely on open standards, including the MCP protocol; they are included in every plan, at no extra cost, within the number of connections your level includes. Only the fees charged by the platforms themselves — WhatsApp Business bills per conversation — are passed on at actual cost, with no margin, outside the subscription.
