In general those possible custom fees vary between 5-20% on the purchasing value depending on the item and the customs officers mood when clearing it.... This is really not in our hands! Some customers get lucky and do not have to pay anything and some are charged an additional 5-20%. So please be aware of these fact when you are ordering from a country outside the European Union. If you might return the item within your 14 days return period you will get a full refund of the purchased goods including possible customs you might have paid for.
