The European Union member states gave the green light to implement the Brexit deal on January 1 after unanimously approving the deal.
The agreement regulates the trade relationship after the UK's exit from the European Union.
The EU and British negotiators reached a post-Brexit trade agreement last Thursday.
The deal will remain for British exports to comply with health and safety standards set by the European Union, while strict rules govern products made with ingredients sourced outside the UK or the European Union.
European Commission President Ursula von der Leyen said the Brexit deal was "good, balanced" and "fair" for both parties.
Any British visitor to the EU will also have to make sure their passport has enough validity when they begin their journey.
