Service scope

Registration, monitoring and ongoing MRN handling

Without confirmation that an order has been accepted, transport is harder to plan. Late registration or an unresolved hold may prevent loading onto the planned vessel. We continue handling the order after a reference has been issued: we monitor available statuses, coordinate inspection formalities and update the registration after transport changes.

Monitoring customs and port statuses

We monitor available clearance and loading statuses, including messages about holds, document checks, container scans and physical customs inspections. We report release confirmations received, missing documents and when we are waiting for customs or the terminal. If a message does not explain a hold, we seek clarification from the relevant party and tell you that verification is underway. We check customs or terminal requirements, and the updates we share help you plan transport and inform your client.

We monitor available registration and shipment statuses within the scope and period covered by the order.

Port registrations

We verify the MRN, container and booking details and register the shipment in the port or terminal system.

  • Z-Nummer
  • BHT
  • WHT
  • Portbase
  • APCS/e-Desk

After registration, we send you the reference or confirmation.

Handling transport changes

A booking, vessel or terminal change may require an amendment or a new registration. We verify the current status and handle the change under the rules of the relevant port system. You receive confirmation of the update or a new reference.

We agree any additional charge before carrying out the work.

What to send after a roll-over

Contact with the team handling your order

If a container is held or selected for inspection, you can contact the team handling your order. We share document requirements, progress updates and any release confirmations received. If action is needed from the forwarder or declarant, we explain what they need to do.

Main and additional ports

Our five main ports are Hamburg, Bremerhaven, Wilhelmshaven, Rotterdam and Antwerp. We also handle cases in Amsterdam, Zeebrugge, Gdynia and Gdańsk, Bremen, Cuxhaven and Vlissingen. We check the applicable registration process for the specific location and terminal.

Guide: documents for port registration

Before your first order

Can you handle an MRN prepared by another agency?

Yes. Send your booking and export document with the MRN. We will handle the port formalities. You do not need to order another export declaration from us.

Which documents should I send first?

Send:

We will let you know if we need any further details.

Can one agreement cover several ports?

Yes. Select all required services and ports in your enquiry and provide the approximate monthly volume. For Portbase, we confirm availability for the specified terminal.

How do I report a booking change?

Send:

  • The new booking
  • The existing reference
  • A note of what has changed

We verify vessel, voyage and terminal details and the registration status to establish whether an amendment, cancellation or new registration is needed. We confirm any additional charge before proceeding.

Do you help if a problem arises after the reference has been issued?

Yes. We help with loading holds, document checks, container scans and physical customs inspections. We verify customs or terminal messages and coordinate formalities within the scope of the order.
