Case of classification of unassembled goods OR How to save €389 973?

An unassembled good must be classified as a complete good. For example, if you import disassembled bicycles, you still have to declare them as bicycles and pay the import duties due on the bicycles. But maybe you could be smarter and save the import duties by declaring half of the bicycles’ parts in your name and the other half in a friend's name? In addition, perhaps it would help to place the parts under different customs procedures before releasing them for free circulation?
