The BREXIT transition period will expire on 31st December 2020 23:00 GMT. The United Kingdom is due to leave the European Commission under the terms of the Northern Ireland Protocol, special consideration has been made to protect Northern Ireland cargo due to its soft border with the Republic of Ireland. Under this agreement Northern Ireland does leave the European Commission with the rest of the UK, but remains part of the European Customs Union. There will be a grace period of 6 months given for the trades from European Union to Great Britain, but any cargo movement from Great Britain to European Union will require an existing Entry Summary Declaration (ENS).
Therefore, it is important, especially for the short transit services from Great Britain to the European Union, to follow the Advance Security filing procedures, as from 31st December 2020 Great Britain will be treated as any other country outside European Customs Union.
Any cargo movement from Great Britain to European Union will require an Advance Security filing – Entry Summary Declaration to EU Customs. This is the same procedure followed for cargo movement from any third country to European Union. This also covers the transhipment and Freight Remain On Board (FROB) cargo. Hence you will be required to submit full Shipping Instructions at least 24 hours prior to vessel arrival at Great Britain. In the case of weekend arrivals, this will mean by latest 17.00 Thursday. For traffic subject to Chinese pre-manifest, this continues to be 48 hours prior to vessel arrival.
