Export from EU to the UK: Unfortunately after the UK transitional period ends, UK registered businesses cannot act as an EU Exporter, therefore UK businesses will need an EU registered company to act as an exporter or a representative for them in order to export goods from the EU. You will also need an EU EORI number (issued by the EU member state) to be able to operate your export model. (you will even need this if you are using a custom agent or forwarder for export declarations. What do you need for this? Technical Agreement, the UK importer and EU exporter should agree on terms and conditions to clear the responsibility for tariffs, duties and border. UK Authority will need to be pre-notified about the arrival of pharma goods.
Importing GB to EU: The same requirements for businesses importing goods into the EU, they will need EU EORI number issued by EU member state, even if using forwarder of custom agent for import declaration. Certificate and licenses still mandatory to have to be able to import. EU Authorities will need to be pre-notified about the arrival of pharma goods.
There are different requirements for EU ports/ terminals ( Ireland, France, Spain, Netherland, Belgium). Must check their own requirements before using the ports/ terminal.
