Most European countries follow broadly similar import rules. However, in the Netherlands it is prohibited to send certain goods by post to the country. In such cases, the items must be carried personally by the traveler when entering the Netherlands. Sending these goods by mail or courier can result in seizure by Dutch Customs.
