Why are costs charged for the import service but not for the export service?

The costs for the import process in terms of security, liability and the amount of connections that need to be made (ICT costs) with various parties are much higher than for the export process. Notification Import Documentation results in a faster and more efficient process for companies involved in imports and logistics. These costs are not fully covered by the terminals and shipping lines (due to the added value for importing companies). Because of its cost-based and non-profit basis, Portbase has no other option but to pass on these costs to the user.
