In Portugal it works something like this. If it's below 100€ it's very likely not to be taxed (but not sure if it's a hard rule) if it's above it gets stuck in custums you have to send the purchase documentation and you're charged for VAT (23%). Any other costs if exist are very low value compared to the rest.
