The UK has proposed that a common rulebook for goods including agri-food should underpin the UK-EU free trade area. As set out in the White Paper, the common rulebook would cover those rules which are necessary to provide for frictionless trade at the border between the UK and EU.
In the case of manufactured goods, this encompasses all rules that could be checked at the border, as they set the requirements for placing manufactured goods on the market. For agricultural products, food and drink, this includes relevant Sanitary and Phytosanitary (SPS) rules, but excludes those relating to wider food policy.
With regards to goods exported from the UK to countries outside of the EU, UK firms will, as now, be able to manufacture products that meet the regulatory requirements of those countries.
