The European Union (EU) has free movement of goods. When goods are imported from a country outside the EU, they can initially be stored under customs seal. This allows you to postpone or avoid import duties (and other taxes). Moreover, at this moment, import restrictions and other trade policy measures do not apply. This provides you with a competitive advantage and a higher profit margin. In fact, the goods often leave the EU to be sold in other parts of the world, and you can only declare the goods when it is most suitable for you.
