You will be subject to customs clearance in the same way that businesses currently do when importing goods from outside the EU. This means that you will need to make an import declaration for goods entering the UK from the EU.
You should consider how you will submit import declarations and it is up to you whether you chose to make declarations yourself or have Banks & Lloyd complete these on your behalf. Keep in mind that Banks & Lloyd process customs clearance all in house, simplifying the entire process, and should you wish to discuss this further then do not hesitate to contact us. If you do choose to do it yourself, you will need the right software and the necessary authorisations from the HMRC.
