According to 2007/46 EC (which is the set of rules of european car industry) , any second stage maker could perform 2nd stage small series including any transformation into a vehicle and allowing it to transform in that way a small number of vehicles without additional tests. If you are planning to sell a transformation over a little number of new vehicles of a defined type along all the european union, you might consider this option. National Small Series (NKS) are limited to the state which emits them, and although it might be admited in the rest of the UE , it is not mandatory for the other states to do it. If you are a second stage maker and you need to perform a KS , contact us with the form below. Explain us in a few words what you need and over which vehicles and we will contact you soon.
