Registering a car purchased abroad in France involves a technical step that is often poorly anticipated: the inspection by the mines, or isolated type approval (RTI). Depending on whether the vehicle comes from a European Union member country or a third country, the administrative process, required checks, and final invoice can vary significantly. Assessing these differences before signing an order form abroad allows for evaluating whether the operation remains financially viable.
RTI for imported vehicles: cost and complexity based on geographical origin
The fundamental distinction lies in the existence, or absence, of a European Certificate of Conformity (COC). This document, issued by the manufacturer for any vehicle approved in the EU, determines the complexity of the homologation process in France.

| Criterion | Intra-EU vehicle with COC | Non-EU vehicle (USA, Japan, etc.) |
|---|---|---|
| Key document | European Certificate of Conformity (COC) | No recognized equivalent in France |
| Mandatory DREAL inspection | No (except in special cases) | Yes, almost systematic |
| Additional UTAC tests | Rarely required | Frequent (noise, pollution, braking) |
| Indicative cost range | Limited to registration fees and technical inspection | Can exceed several thousand euros with tests |
| Average observed delay | Several weeks | Several months depending on DREAL |
For a European vehicle where box K (approval number) and box D2 (type approval) are correctly filled in on the foreign registration document, it is sometimes possible to do without the paper COC. The assessment is up to the CERT (Expertise and Resources Center for Titles).
On the other hand, a vehicle imported from the United States or Japan falls into the most restrictive category. The absence of European approval triggers a complete RTI with DREAL, accompanied by technical tests delegated to UTAC.

Tax clearance and tax declaration before registration
Before any request for a registration certificate, the owner must obtain a tax clearance from the business tax service (SIE) corresponding to their residence. This document certifies that VAT has been paid or that the vehicle is exempt. The legal deadline for this declaration is 15 days after the vehicle enters the territory.
A detailed guide helps to understand the steps for the inspection of a foreign car and anticipate each stage of the process.
Expatriates who repatriate a vehicle registered in their name for more than six months as part of a move are a special case. Under certain conditions, they may benefit from a VAT exemption on import, which significantly reduces the overall cost of the operation.
RTI file at DREAL: the documents that really cause delays
The official list of documents is long, but some items account for the majority of rejections and delays. Three documents deserve special attention.
- The Certificate of Conformity (COC) or, failing that, a statement from the manufacturer confirming the technical characteristics of the vehicle. For older models or brands that are not widely distributed in Europe, obtaining this document can take several weeks and cost several hundred euros.
- The French technical inspection report less than six months old, carried out in an approved center. An inspection conducted in the country of origin is not acceptable.
- The proof of purchase (invoice or sales contract) accompanied by the original foreign registration document, essential for establishing the vehicle’s history and verifying the absence of opposition.
For non-EU vehicles, DREAL may require UTAC test reports on noise, emissions, and braking. These tests are billed directly by the laboratory and represent the heaviest budget item in the process.
Environmental penalty and highly polluting imported vehicles
The calculation of the penalty also applies to imported vehicles, whether new or used. For a used vehicle, the amount of the penalty is reduced based on age, but the calculation base remains linked to the declared CO2 emissions.
DREAL’s policy has tightened in recent years regarding highly polluting or heavily modified vehicles. American pickups, muscle cars, or certain Japanese sports cars are subject to more frequent requests for additional tests, which extends the delays and increases the costs well beyond the standard RTI file.
A classic RTI file (compliant vehicle, few modifications) generally remains within a range of a few hundred euros. In contrast, a non-compliant vehicle can reach a homologation cost that makes importation economically questionable, especially if the environmental penalty is added.

ANTS registration after approval: what finalizes the file
Once the RTI is obtained (or the COC validated for a European vehicle), the request for a registration certificate is made exclusively online on the ANTS website or through an authorized professional. The cerfa form 13750 serves as the registration request and Certificate of Conformity.
- A valid identification document of the holder.
- A proof of residence less than six months old.
- The tax clearance issued by the SIE.
- The RTI report (for non-EU vehicles) or the COC (for intra-EU vehicles).
- The vehicle insurance certificate, mandatory as soon as it circulates on the territory.
The processing time varies according to the workload of the services, but the holder has one month to register the vehicle after its acquisition or entry into France.
The cost and complexity gap between intra-EU imports and non-EU imports remains the decisive factor. For a European vehicle with its COC, the procedure is akin to a simple change of registration. For an American or Japanese vehicle without community approval, the inspection process can take several months and a budget that can turn an apparent good deal into a financially unviable operation.
