evidence: While no customs export declaration forms would be required (as Northern Ireland will remain in a UK-wide customs area), exit summary declarations will be required to move goods between Northern Ireland and Great Britain. These declarations represent a new intervention, in addition to existing checks. [...] If the UK leaves the EU under the current agreement, and Northern Ireland remains as an integral part of the UK and thus its single customs territory (i.e. not part of the EU customs territory), there would be no question of Northern Ireland persons (individuals and businesses) having to complete an EU customs declaration/export declaration of bringing goods originating in Northern Ireland across to Great Britain. [...] Nonetheless, having to complete exit summary declarations is a new requirement, as an outcome of the current agreement. It is not accurate to say that there will be no forms, checks, or barriers of any kind for goods leaving Northern Ireland to Great Britain.
