The deal (1,245 / 8MB PDF) was agreed on 24 December and will define the post-Brexit trading relationship between the EU and UK from 1 January 2021.
The no-deal planning undertaken over the last two years will certainly not be wasted, as businesses in all sectors will need to adapt to new ways of trading between the UK and EU, and the additional costs involved.
The UK government plans to pass emergency legislation today to implement and ratify the agreement. The EU will apply the agreement provisionally from 1 January, pending ratification, so that the European Parliament can consider the agreement in early 2021 before the EU ratifies it fully. This means the EU will have the opportunity to review whether the UK's legislation fully implements the agreement, before it decides to proceed with ratification.
Import and export of goods
The free trade grand prize in the agreement is the continued absence of tariffs or quotas on goods imported and exported between the UK and EU. However, this applies only for goods meeting the agreement's rules of origin. For example, at least 55% of the materials making up a car must originate from the UK or EU for it to be imported tariff-free. Businesses dependent on international supply chains will need to assess the impact for them of the rules of origin.
As the UK has left the EU's Customs Union there will be customs paperwork and checks for goods crossing the UK-EU border, even if no tariff is payable. These are required from 1 January on both sides of the border, although the UK has provided a transitional period until 1 July 2021 with extended deadlines for paperwork to be filed on imports to the UK. Businesses importing or exporting goods across the border will need to register, or instruct a customs agent on their behalf.
Although the agreement permits food imports and exports to continue, they will be subject to checks and controls at the border, because the EU and UK have not agreed to recognise one another's standards and safeguards.
The increased friction at the border will cause delays and increase costs for supply chains. Businesses will need to adapt, particularly where they are reliant on speed of delivery. The delays are likely to be a long term feature of trade, with peaks in January-February 2021 as the new arrangements bed in, and in July 2021 when the UK's transitional arrangements end.
Product standards regulation
The agreement contains limited provisions for the UK and EU authorities to cooperate on the regulation of goods and product standards. However, for the most part businesses will now need to comply with two different regulatory systems in the UK and EU, including conformity assessments, if trading in both.
A notable exception is in relation to medicinal products. An annex to the deal establishes mutual recognition of inspections and good manufacturing practice, removing much of the duplicate regulation.
Northern Ireland
The agreement does not expressly address trade in Northern Ireland, as this is governed by the Northern Ireland Protocol to the UK-EU Withdrawal Agreement. However, because the Protocol essentially provides for Northern Ireland to form part of the EU's single market, the impact of most of the provisions on trade in goods will relate to trade between Great Britain and Northern Ireland, rather than Northern Ireland and the EU.
Services
The agreement contains limited provisions on trade in services. Whilst it establishes some general principles of market access, these are subject to a long list of wide-ranging reservations annexed to the agreement. UK providers operating in the EU need to verify if their service is subject to one of the exceptions and, if it is, whether there are national restrictions they are subject to in particular EU member states.
Movement of people
UK and EU citizens who established EU free movement rights before 31 December 2020 retain them under the UK-EU Withdrawal Agreement (198-page / 2MB PDF) concluded in November 2019, if they have registered their settled status under the schemes set up by the UK or EU by 30 June 2021.
