The Brexit transition period will end on 31 December 2020. Trade between the European Union and the United Kingdom shall be governed by a free trade agreement or, if the terms of this Agreement are not mutually accepted, import and export shall be governed by the terms of the World Trade Organization. From a customs point of view, it is therefore necessary to prepare yourself for the standard customs process, linked to the possible payment of customs debts, i.e. payments of customs duties and VAT. Of course, the changes will also affect excise duties. It will be necessary to apply for EORI number and declare the JSD and VDD documents on import or export. Trade will no longer be reported in the Intrastat system.
