The certificate of conformity, and what to do when there isn't one
It is the slowest document in an import, the one nobody can speed up, and the one on which a badly prepared purchase comes to a permanent halt.
What a COC actually proves
The European certificate of conformity, the certificat de conformité européen or COC, states that a vehicle conforms to a type approved at European level. It is issued by the manufacturer, and it carries the technical figures the French authorities then copy onto the carte grise, the French vehicle registration certificate: mass, emissions, power, noise level, number of seats.
That is its entire purpose. Because those figures come certified by the manufacturer, the car can be registered without an individual technical examination of the vehicle. Nothing has to be measured or tested one car at a time: the certificate already says what the vehicle is.
A COC describes a vehicle, not a situation, which is why it carries no expiry date. One issued five years ago is still perfectly usable, provided the car has not been modified since.
Who issues it, what it costs and how long it takes
Only the manufacturer, or its official representative in France, can issue a COC. No broker, no garage and no government office can produce one in its place; the most anyone else can do is order it for you.
| Question | Answer |
|---|---|
| Who issues it | The manufacturer, or its official representative in France |
| What it costs | 100 to 300 EUR, depending on the make |
| How long it takes | One to three weeks, seven to twenty-one days in practice |
| Who pays | You do, at cost. We add nothing to it. |
Some manufacturers turn the request round in a few days, others take a month, and the difference has more to do with how the brand runs its back office than with the car itself. It is not a cost we make anything on: the manufacturer invoices the certificate and we bill it on at cost, without a margin.
It is also the one item nobody can speed up, which is why we order the certificate on the day the car is bought, while it is still on its way back. Every other step of an import moves faster than the manufacturer does.
The question worth asking before the car is bought
Ask the seller whether the car comes with its original COC. Some are sold with it, particularly when the German seller is a franchised dealer for the make, and that single answer takes three weeks out of the timescale.
It is the first thing we check before committing to a purchase, for exactly that reason. The question costs nothing to ask, and it is worth asking while you can still walk away from the car.
The three cases where no COC exists
Three situations make the certificate impossible to obtain:
- a vehicle that came from outside the European Union and was therefore never type approved in Europe;
- a vehicle that has been modified and no longer conforms to its approved type;
- an older model for which the manufacturer no longer supplies a certificate.
An import from the Japanese market, a car with a modified exhaust or suspension, a model the manufacturer no longer covers: that is what those three cases look like on a forecourt.
None of it is visible in the listing, and none of it becomes the seller's problem once the money has moved. A car bought without checking this first is where an import gets stuck for good.
Réception à titre isolé: individual approval by the DREAL
When no COC exists, the way out is the réception à titre isolé, the individual approval route. It is handled by the DREAL, the direction régionale de l'environnement, de l'aménagement et du logement, the regional state body that handles individual vehicle approval in France.
The car is then assessed on its own rather than against a manufacturer's certificate. The vehicle may have to be put on a rolling road, and work may be required to bring it into line before approval is granted. It takes longer than a COC, it costs more, and there is no guarantee of success.
What comes out at the end is a procès-verbal de réception à titre isolé, the individual approval report, and it stands in for the COC when the car is registered. It is a route, not a formality, and it is worth knowing you are on it before you own the car rather than after.
Why we would rather tell you no before you pay
This is exactly the kind of purchase where somebody has to say no, and say it before you pay. A car that has been bought and then cannot be registered is not an inconvenience, it is a dead loss.
So the checks happen first: whether the certificate exists for that particular car, whether the manufacturer still issues one, and whether anything about the vehicle takes it outside its approved type. When the answer is bad, we say so while walking away is still free.
Where the COC sits in the rest of the paperwork
The COC is one document among five, each with its own cost and its own lead time. To register an imported car in France you need:
| Document | What it is |
|---|---|
| Foreign registration certificate | The registration document from the country the car comes from, or the certificate of sale. |
| COC, or the individual approval report | Proof that the vehicle conforms to an approved type, one way or the other. |
| Quitus fiscal | Properly the certificat fiscal 846 A: the clearance from the French tax office confirming that the vehicle's VAT position is in order, either because VAT has been paid or because none is due. For a car from outside the EU, customs clearance takes its place. |
| Contrôle technique | A French roadworthiness test, less than six months old, for any vehicle over four years old. |
| Identity and address | Proof of both, in the name of the person the car will be registered to. |
The certificate also decides what the registration costs, because the registration authority reads its figures straight off the COC. The power it certifies is what the puissance fiscale is derived from, counted in chevaux fiscaux, the French fiscal horsepower rating: in Centre-Val de Loire the regional tax is 60 EUR per cheval fiscal in 2026. The CO2 figure sets the CO2 malus, and the masse en ordre de marche, the mass in running order with fluids and driver included, sets the weight malus from 1,500 kg upwards.
The timings are worth keeping in proportion. The quitus fiscal takes twenty-four to forty-eight hours when the paperwork is complete. The certificate of conformity takes one to three weeks. There is only ever one bottleneck in an import, and this is it.

If you would rather not handle any of this
Send us the link to the listing. You get the complete price and the tax calculation before anything is committed. We buy the car, we bring it back, and you buy it from Autonero: a French invoice and the two-year legal guarantee of conformity that comes with buying from a French dealer. 40% on order, the balance on delivery.
That is the difference with a mandataire, an agent who buys the car in your name: with a mandataire the seller remains the foreign one and your recourse stays abroad. Here you are buying from us, and we are six kilometres from Chartres.
The certificate of conformity, the quitus fiscal, the contrôle technique and the registration itself are ours to deal with. The car is handed over ready to drive, with the carte grise already in your name.

Do I need a certificate of conformity to register an imported car in France?
For a car coming from a European Union country and approved as a European type, yes: that is the normal route, and the registration application will not go through without it. For a vehicle from outside the Union, or one that was never type approved, no COC exists and none can be created after the fact; the réception à titre isolé replaces it.
Who issues the COC and how much does it cost?
Only the manufacturer, or its official representative in France, can issue a COC. Budget 100 to 300 EUR depending on the make, and expect the price to vary more from one brand to another than from one model to another. Anyone else can only order it on your behalf, which is what we do: the manufacturer invoices the certificate and we bill it on at cost, without a margin.
How long does a COC take to arrive?
One to three weeks, so seven to twenty-one days in practice. Some manufacturers answer in a few days, others take a month, and nobody can push them. That is why we order the certificate on the day the car is bought, while it is still being transported, instead of waiting for it to arrive: the wait then runs alongside the rest of the import rather than after it.
Does a certificate of conformity expire?
No. It has no expiry date because it describes a vehicle, not a situation: a COC issued five years ago is still usable, as long as the car has not been modified since. That is the opposite of the quitus fiscal, which records a tax position on a given date and loses its value once that position changes.
Can I register a car in France with a COC written in German or Italian?
Yes. The European certificate of conformity is a harmonised document, drawn up to the same pattern and recognised in every member state, which is precisely what makes it useful across borders. No translation is required.
Is the COC the same thing as the German Zulassungsbescheinigung Teil II?
No, they are two different documents, and a German import normally needs both. The Zulassungsbescheinigung Teil II is the German registration document: it records the registered keeper and the vehicle's registration history, and it is not, in German law, proof of ownership. The COC is the manufacturer's statement that the car conforms to a type approved at European level. One tells you what has happened to the vehicle, the other tells you what the vehicle is.
There is no COC available for my car. What happens then?
The car goes through the réception à titre isolé, the individual approval route handled by the DREAL. The vehicle is examined individually, it may have to be put on a rolling road, and work may be required to bring it into line before approval is granted. It takes longer, it costs more, and the outcome is never certain. The approval report that comes out of it then stands in for the COC when the car is registered. This is worth establishing before you buy the car, not after.
Does the COC replace the quitus fiscal?
No. They answer two different questions, and to register a car from another member state you need both. The COC is technical: it certifies that the vehicle conforms to an approved European type. The quitus fiscal, properly the certificat fiscal 846 A, is the clearance from the French tax office confirming that the vehicle's VAT position is in order, either because VAT has been paid or because none is due. For a vehicle coming from outside the Union, customs clearance replaces the quitus.
Can you check all this before I commit to a car?
Yes, and it is the whole point of asking early. Send us the link to the listing and we check whether the car already comes with its original COC, whether the manufacturer still issues one for that model, and whether anything about the vehicle takes it outside its approved type. You get the complete price and the tax calculation before you commit to anything. Call +33 9 80 80 15 10 or use the import enquiry form.
