The Certificate of Conformity (COC) is an essential document in certain processes related to vehicle registration in Spain, especially when it comes to cars imported from another country. This article explains what the COC is, its utility in the registration process, and how to obtain it, as well as alternatives in case you do not have this certificate.

What Is the Certificate of Conformity (COC)?

The Certificate of Conformity is a document issued by a vehicle’s manufacturer that contains all the technical specifications of the car and certifies that it complies with European regulations. This certificate is typically provided when purchasing a new car directly from an official dealership.

The COC includes key technical information, such as:

• Vehicle dimensions.
• Engine and fuel type.
• CO₂ emissions.
• Vehicle Identification Number (VIN).
• Other technical data that ensure the vehicle meets European standards.

What Is the Purpose of the COC in Spain?

The COC is particularly useful when you want to register in Spain a vehicle imported from another country. This document facilitates and speeds up the process at the Vehicle Technical Inspection (ITV) stations, as it:

1. Avoids additional documentation: If you present the COC at the ITV, you do not need to provide additional technical reports about the vehicle’s specifications.
2. Saves money: Without the COC, it is necessary to hire an engineer to prepare a technical report for the vehicle. This process can be costly, whereas the COC is usually free.

What Happens If You Don’t Have the COC?

If you do not have the Certificate of Conformity, you will need to obtain a technical report from a specialized engineer. This report certifies the vehicle’s technical specifications in accordance with Spanish and European regulations. However, this alternative has several drawbacks:

• Higher cost: The technical report can be considerably more expensive compared to the COC, which is generally issued free of charge.
• More time and complications: It requires coordinating the vehicle’s inspection with a professional, which can delay the registration process.

How to Obtain the COC

1. When purchasing a new vehicle

When you buy a new car from an official dealership, the COC is automatically provided along with the vehicle’s documentation. It is important to keep this document for any future procedures.

2. If the car is already in Spain

If you have imported a car from another country and need the COC, you must request it from the dealership or the brand’s official representation in the country of origin. Key points to keep in mind:

• You cannot obtain it in Spain: Even if the brand has a presence in Spain, only the dealership or official representation in the country where you purchased the car can issue the COC.
• Verification of the VIN: In many cases, the official representative needs to verify the Vehicle Identification Number (VIN) before issuing the COC. This can be challenging if the car is already in Spain, as the inspection may need to take place in the country of origin.

3. What to do before bringing the car to Spain

To avoid problems and additional costs:

• Before transporting the car to Spain, visit the dealership where you bought it or the brand’s representation in the country of origin and request the COC.
• This is a simple and free process in most cases.

Practical Tips and Conclusion

• Request the COC in advance: If you plan to import a car, organize this process before moving the vehicle to Spain.
• Keep the COC safe: Once you have it, store it securely along with the car’s documentation.
• Consult a specialist: If you are unsure about the registration process, a professional advisor can help you avoid mistakes or delays.

The Certificate of Conformity (COC) is a key tool to simplify the registration of imported vehicles in Spain, avoiding additional expenses and complex procedures. Whenever possible, request this document in the vehicle’s country of origin before bringing it to Spain. This will allow you to complete the registration process more quickly and cost-effectively.
