In the eventuality that the United Kingdom (UK) leaves the European Union (EU) under a "No Deal" Brexit scenario on 29th March 2019, we take this opportunity to inform you that this will cause immediate changes to the documentation required for items of mail posted to countries within the EU, to fall in line with current rest of world documentation requirements.
At present, postal items posted to countries within the EU are not subject to customs charges but this would change from 29th March 2019 under the "No Deal" Brexit scenario. All items posted to destinations beyond the UK (Europe and rest of world) will require a CN22 customs declaration label if valued at under £270 or a CN23 customs declaration label for items valued over £270, declaring a full description of contents and their value.
At the time of writing, it is unclear whether there will be a delay to Brexit and therefore these changes may not come into effect on 29th March 2019 but at a date to be announced by the UK Government.
