K24, I read a bit about someone in a similar situation that in addition to the shipping VAT was added bringing the total to more than the cost of new things in the EU.
edit to add, Here's the FB post showing this, " This is good but at the same time causing lots of trouble. I know a girl that is in Poland, and her friend sent her used personal belongings from Ukraine to Poland. Delivery cost 5000 uah, reached Poland and there is 120€ tax on it, and tax office/customs grants no exceptions to a refugee. And this girl have no work, no money, and without paying this tax they are not handing over the shipment to her.
Moral of the story: she could have bought all the stuff new for $500 "
