It is is even more difficult as there is no such thing as EU law for customs violations. In Germany the ownership and import of counterfeit goods is exempt from punishment as long as it does not serve the purpose of making profit. In France you can end up with a fine of 10.000 € regardless. In the case described above it is not about punishment though but compensation for damages. Now I would say there is no damage done, unless you imported the goods to sell them which can hardly be assumed unless you buy a batch of 50 pcs. or so. The amicable settlement they suggest is to avoid a law suit. So if you don't pay they would have to sue, but on what grounds? I am not familiar with Belgium law but as it presents itself to me they got nothing on you. I agree that the easiest way out is simply denying that you order the bracelets in the first place.
