The final phase of post-Brexit food labelling requirements for products shipped from Great Britain to Northern Ireland has come into effect.
The new rules extend "Not for EU" labels to cover eggs, fish, fruit and vegetables, some composite products and other items.
The labelling system forms part of the Windsor Framework and has been gradually introduced since 2023.
Meat products have required the labels since October 2023, with dairy products following in October 2024.
Government expects deal to end labels
The Government believes the labels will become unnecessary once the UK and EU finalise a new agrifood deal.
The labelling requirements exist under Windsor Framework rules to ensure goods are not moved onwards from Northern Ireland into the rest of the EU.
The Windsor Framework replaced the Northern Ireland Protocol and means the region must adhere to certain EU laws regarding goods.
Business leaders criticise "bureaucratic madness"
The extension of labelling requirements has drawn criticism from some major retailers.
Stuart Machin, the CEO of Marks and Spencer, recently branded the extension "bureaucratic madness" and said a new agrifood deal "can't come soon enough".
It is believed that the Government does not expect any products to become unavailable in Northern Ireland due to the new labelling regulations. However, officials are preparing contingency measures to address any potential supply disruptions.
