Customs representation
Portbase registration, import, export and DVA arrivals. Your declaration to Dutch customs, carefully prepared, checked and traceable.
Status: Available

Portbase is the platform through which information about goods in the Dutch ports is exchanged. A Portbase registration can be used for both import and export and is therefore a service in its own right.
Customswise.online supports the Portbase registration, so that it can afterwards be used for both import and export.
- Portbase registration as a stand-alone service
- Usable for import and for export
- Tied in with the customs handling by Customswise.online
Every import shipment carries responsibilities. The data must be complete, the documents must match each other and the declaration must fit the actual flow of goods. Customswise.online supports importers with the full customs handling of incoming goods, including advance declarations, Portbase processes, DVA arrivals and import declarations.
We look beyond filling in declaration data. Beforehand we assess the information you supply for completeness, consistency and usability, so that possible issues are spotted and dealt with early.
- Advance declarations and Portbase processes
- Import declarations on your behalf
- Assessment up front for completeness, consistency and usability

For goods arriving through Dutch seaports, customs handling can often be prepared before the goods leave the terminal.
Through our link with Portbase, import declarations can be prepared and filed in good time, so the necessary customs formalities are dealt with as early in the process as possible. Where possible, release then follows straight on from the logistics process, which prevents needless delay.

An export declaration is often the last formal step before goods leave the European Union. That is exactly why correct handling matters so much.
We handle export declarations for a wide range of goods flows and support companies with the preparation and checking of the required documents. Our focus is not only on a timely declaration, but above all on an export file that can be followed, demonstrated and defended afterwards.

Data exchange in the way that suits your organisation
Not every company works the same way. Some clients prefer a traditional approach in which commercial invoices, packing lists and transport documents are supplied. Others process larger volumes every day and want further automation. That is why Customswise.online offers two ways of working together.
Route 1
Document-driven processing
A practical solution in which the required documents are supplied per shipment and checked before the customs formalities are carried out.
Route 2
EDI integration
For organisations with structural goods flows, a project-based link can be set up in which declaration data is made available directly from your internal systems for customs handling.
The result is efficient data exchange without compromising on control, quality or compliance.
One point of contact for your customs handling
Whether it is a one-off import shipment, a recurring export flow or the processing of DVA arrivals: Customswise.online helps you with controlled, professional and future-proof customs handling.
Practical where it can be. Careful where it must be. Always compliant.
