Updated on .Source:Applying for license plates for an imported vehicle (gov.pt / IMT, in Portuguese).
What it is
The COC (Certificate of Conformity) is issued by the manufacturer and certifies that the vehicle matches a model type-approved in the European Union. It contains the approved technical specifications — CO₂ emissions, engine size, weight and dimensions — and the emissions test standard, WLTP or NEDC.
What it is used for in the legalization
- It is the basis for type approval in Portugal: the IMT converts the model's European type approval into a national one from it.
- It is the basis for calculating the ISV, because it states the CO₂ emissions and the engine size — and the standard, which determines which table applies.
- Without national type approval, the IMT fee rises from €45 to €165.
How to get it
It may come with the car, if the seller has it. If not, you order it from the manufacturer or a specialized service. At ComfyLand you order it on the COC page, through our partner COC Online: all you need is the chassis number (VIN), and it covers European makes.
I already have the COC
Attach it to the legalization request. The team checks that it is complete and suitable for the process. Before you buy, it is also a good idea to check the car's history by VIN — see the VIN check.
