The Irish Sea border for food and agricultural products will not be dismantled until 2027, a UK government minister is expected to confirm on Wednesday.
The sea border refers to post-Brexit checks and controls on products moving from Great Britain to Northern Ireland.
In May this year the UK and EU agreed an outline deal which, when implemented, will mean no physical checks on GB food products at NI ports.
The implementation timetable was unclear but EU relations minister Nick Thomas-Symonds will give an update in a speech later.
It is expected that further negotiations with the EU will happen in the autumn with a view to UK legislation in 2026 and implementation in 2027.
The outline deal is based on the UK agreeing that it will align with EU rules on agri-food which will mean Northern Ireland and Great Britain return to following the same set of rules.
That will mean food being shipped from Great Britain to Northern Ireland will no longer need the paperwork and checks which have been in place since 2021.
The deal will also cover the trade in horticultural products like seeds and garden plants.
Northern Ireland’s current trading arrangement came about as the result of a Brexit deal between the EU and UK in 2019, which was revised in 2023, and is now known as the Windsor Framework.
They agreed that the most practical way to keep the border open between Northern Ireland and the Republic of Ireland was for Northern Ireland to follow many EU laws on the regulation of goods.
However this means that goods coming from the rest of the UK into Northern Ireland face checks and controls to ensure they meet EU rules.
This arrangement has become known as the Irish Sea border.
It has had a particular impact on the food industry as Northern Ireland supermarkets are still largely supplied from distribution centres in England and Scotland.
New border control posts have been built at NI ports to facilitate checks on food products arriving from GB.
The new deal should substantially reduce the impact of the sea border for food and plants as there will be no regulatory differences between Northern Ireland and Great Britain.
However it will not remove the need for customs paperwork.
