Companies that deal with animal products, including seafood producers, are being urged to prepare for changes in the requirements for export and import that comes with the impending Brexit.

The full list of requirements is now available online, with a special page detailing how to export fish, as seafood products will require additional paperwork to ensure they were legally caught, including a catch certificate and export health certificate.

New regulations follow the same rules currently in place for exports of seafood to some non-EU countries. Seafood that is either caught by a UK-flagged vessel or landed in the UK will also need to send all consignments of seafood products through an EU border inspection post (BIP).

Importers will be shifting to rules under the Import of Products, Animals, Food and Feed System (IPAFFS) to notify authorities of their shipments. Users are encouraged to register for IPAFFS from Sept. 30, when guidance and user support will be available.

"While the Government is seeking a deal with energy and determination, we have stepped up our preparations and we will be fully ready to leave the EU on 31 October, whatever the circumstances," said Minister of State for Agriculture for Fisheries and Food George Eustice.
