Parcels can be caught by customs office in each country.
It rarely happens, but customs duty and other taxes like import tariff, additional tax, VAT and etc. may be imposed when the shipment reaches your country.
If applicable, please pay those costs directly to the delivery agents or the customs office. Policies on those taxes vary in each country and you may contact the customs office at your country for more details.
