The Port of Rotterdam is the external border of the European Union, so goods can travel freely throughout the EU after clearing customs. Dutch Customs is responsible for releasing goods that enter or leave Europe through the Port of Rotterdam, and is known to be one of the most efficient customs agencies in the world.

The port has made large investments in recent years to buy high-tech scanning equipment that can thoroughly and efficiently scan 150 containers an hour. Thanks to these scans, containers do not need to be opened unnecessarily, ensuring the safety of cargo while reducing delays and preventing unnecessary costs.
