Interestingly, if you move to Switzerland, for most household items they can demand you prove you've owned it for at least 6 months and that it's not been bought elsewhere and you've avoided paying local VAT on it. So although not the same direct situation, shows that they're pretty hot on cross border purchases, even if you unwrap it and say it's a used good.
