About Us

MRN closure specialists for European seaports

We close MRNs for exporters, freight forwarders, and customs agencies. Filing handling, customs inspections, and the export confirmation delivery in 5 port systems.

Our mission

We exist for one purpose: to eliminate the problem of unclosed MRNs, which costs European exporters millions of euros every year in unwarranted domestic VAT. We combine expert customs knowledge with direct access to port systems so that every case is closed quickly and correctly.

How we work

Every filing is handled by a dedicated customs specialist - from first contact to export confirmation. We work directly in the port systems, without intermediaries.

1

Submit your filing

Send us your MRN and shipment details via our online form, email, or WhatsApp. A dedicated customs specialist takes over the case.

2

Port system registration

The specialist registers your MRN in the relevant port system (ZAPP, BHT, WHT, Portbase or APCS). If there are data discrepancies - they are corrected immediately.

3

Monitoring and closure

We monitor the MRN status until the export procedure is closed by the customs office of exit. In case of issues - we intervene directly in the port system.

4

Export confirmation

Once the MRN is closed, you receive the export confirmation message on your customs account. We notify you when the case is complete.
