In the event of a 'No Deal' scenario, EUR1 and ATR forms - customs documents used in trade between EU members and countries where specific trade agreements exist for preferential tariffs - will no longer be valid for tariff preferences on exports leaving the UK.
The ATR1 Certificate, for goods traded between EU countries and Turkey, and the EUR1 certificate, also known as a ‘movement certificate’, applicable for trade agreements between the EU and beneficiary countries, will be replaced with a new UK version.
The new forms will only be able issued for preferential exports to countries with which the UK holds Preferential/Free Trade Agreements. Currently the UK has agreed trade agreements with Switzerland, Israel, Chile, Palestine, Eastern & Southern Africa (ESA) and the Faroe Islands, whilst talks are ongoing with the other countries currently covered by the EU’s preferential tariff agreements, in order to conclude trade continuity agreements with these countries in the event of a no deal, by exit day (29 March) or as soon as possible thereafter.

In the event of a 'No Deal' scenario the European Community Certificate of Origin forms will no longer be valid for UK exports.
These Certificates will be replaced with a new UK version. The format and layout for the new Certificate will be almost identical to the current EC one.
Should the United Kingdom reach a Withdrawal Agreement with the EU, then the current existing documents will continue to be used throughout any transition period.
