From 1st January 2021, the UK will be treated as a ‘3rd country’. This means that not only are customs declarations required, but the ‘carrier’ needs to submit Safety and Security Declarations (SSDs).
SSDs are also known as ENS (entry summary declaration) or EXS (exit summary declaration) and these need to be submitted in the EU’s Import Control System (ICS) from 1st January or the UK’s equivalent system - SSGB - from 1st July 2021. When goods are shipped driver accompanied, the Haulier is deemed to be the ‘carrier’, and where trailers are shipped on ferries unaccompanied, the Ferry Operators have also moved this responsibility back to the Hauliers, meaning that they are responsible for SSDs regardless of the method of shipment.
In addition to this, to get through the ports you will need to submit a list of your Movement Reference Numbers to either a ‘Port community system’ or ‘Logistics Envelope’ before you can check-in at your port of departure. These systems can be clunky and charge a fee. CustomsLink covers this for you.
