Our service Transit Declaration is used when preparing T-documents for transport to the hinterland. A convenient feature of this service is that it will automatically show a warning if an additional sea in / sea out process (code 27) is attached to your shipment. You can then request the shipping company to correct the error. This prevents mismatches at Customs.
It has come to our attention, together with Customs, that shipping companies and shipbrokers sometimes mistakenly link the Customs process sea in / sea out to a container when submitting their Summary Declaration, even though that particular container has an inland destination. We have since issued a separate Portbase Flash to provide these parties with additional clarification. In the event that a sea in / sea out process has been linked to your inland-bound container, the service Transit Declaration will alert you immediately and you will know how to proceed.
