This model focuses on goods, making it narrower than the single market (which includes services, people and capital). All states in this model apply the same tariff, an import tax on goods entering the union, thereby allowing goods to circulate freely once they are within the EU. This model however would prevent the UK from signing free trade agreements with other non-EU export markets
This model would allow the UK to continue frictionless access to the single market. It would require the UK to abstain from restraints on trade, such as customs duties, and technical barriers to trade. Iceland, Lichtenstein and Norway currently have this status.
The UK leaves the EU without a negotiated arrangement to replace all the legal frameworks and treaties which currently streamline trade relations with the EU. This scenario would provide the most complete break.
This scenario involves building upon the Withdrawal Agreement that the UK negotiated with the EU. A consequence of this is that the UK may not negotiate on goods with states that do not have a free trade deal with the EU, and would be limited to copying existing EU trade agreements. Higher levels of access to the single market may be available through this route, but would involve implementing EU rules in domestic legislation.
