If a Withdrawal Agreement between the European Union (EU) and the United Kingdom (United Kingdom, UK) is not concluded, which would create a transitional period until the end of 2020 (with the possibility of an extension provided for in the withdrawal agreement), the United Kingdom will be treated as a non-EU country (literally as a third country) from 30 March 2019 - this also applies in particular to customs provisions.
The European Commission is now fostering its support in preparing EU companies for such a no deal scenario ("Hard Brexit").
The EU Commission now reiterates that affected companies must take all steps necessary before 30 March 2019 (or before a postponed date) to avoid possible adverse effects. To support this, the European Commission has set up a "Brexit Checklist" and its website with a list of practical tips and recommendations.
