France construction ID card and foreign workers: the first thing a site inspection checks

The carte BTP, the professional identification card for building and public works, is compulsory for every worker performing construction work in France, including a worker posted by a company established abroad. The employer applies for it at the point of hiring, through the union of French CIBTP funds. The worker files nothing.

The obligation sits in article L.8291-1 of the French labour code, created by article 282 of law 2015-990 of 6 August 2015 and put in place by decree 2016-175 of 22 February 2016. It covers permanent contracts, fixed term contracts, temporary agency workers and apprentices, and it covers in exactly the same way workers posted to France by an employer established outside the country. A labour inspector who walks onto a site asks for this card before asking for anything else, because it is the one document that ties a person standing on the site to a declared company.

Who applies, and how long the gap lasts

The application is made by the employer, or by its agent where a foreign company works through a representative in France. It is filed online with the CIBTP, which runs the scheme for the whole sector. The charge is flat: 9.80 euros per card, borne by the employer alone under the CIBTP schedule. Nothing may be deducted from the worker's pay for it.

Between the application and the arrival of the physical card, the worker is not without a document. The CIBTP issues a provisional certificate that the employer hands to the worker and that stands in for the card on site. That certificate remains valid until 72 hours after the company receives the definitive card. After that window the card itself must be produced, and a certificate kept in use beyond it no longer protects the employer during an inspection.

Validity runs differently for an employee and for a posted worker

This is where foreign companies most often get it wrong. For a company's own employee, the CIBTP sets the validity of the card against the duration of the employment contract, and a fresh card is required at every new hiring: a worker who leaves and returns six months later needs a new application and a new charge. For a posted worker, validity follows the duration of the declared posting. If the posting is extended, the card does not follow on its own.

For a posting, the carte BTP comes after the prior declaration, not before it. The order of the formalities matters, and the declaration itself is set out in the SIPSI posting declaration.

What the missing card costs

The penalty is administrative and is issued by the DREETS on a labour inspection finding. Article L.8291-2 of the labour code sets a fine of up to 4,000 euros per worker without a card, rising to 8,000 euros where a second breach occurs within two years, with an overall ceiling of 500,000 euros per company. The arithmetic runs per head: twelve formworkers without cards on one site produce a theoretical 48,000 euro exposure, not a single fine.

Two practical consequences follow. A site of twenty people is inspected in an hour, and the bill is assembled in that same hour. And the principal who admits a foreign subcontractor now reads the carte BTP the way it reads the tax and social security clearance certificate, as a signal of whether the company files its paperwork. A crew arriving with neither card nor provisional certificate is a crew the client may simply refuse to admit, whatever the public authority does afterwards. The rest of what the inspection looks at is covered in illegal employment checks and sanctions in France, and the separate duty to check residence documents in the employer right to work check.

The carte BTP says nothing about whether residence is lawful or whether a posting is valid. It says only that a person present on a site has been declared by an identifiable company. That is exactly why it is asked for first: it is quick to verify and its absence opens the rest of the inspection. If you are preparing work in France with crews recruited outside the European Union, file the card application on the day the contract or the posting declaration is signed, rather than on the eve of departure.
