Expert Customs clearance solutions

We’re able to clear all products in and out of the UK so whatever you are moving, our fully trained team help keep your business moving. Brexit resulted in significant changes to the way goods move in and out of the EU. We intentionally took time to clearly identify our approach and carefully build our team to ensure we are true experts in this new area of customs clearance. Our agents stand out for their knowledge, professionalism and quality service. 

Always on the ground and up to speed, we’ll help you complete customs declarations and make sure your paperwork is correct so that your goods are cleared in a timely, efficient manner. Customs issues can be complicated which is why we offer step-by-step guidance and a comprehensive range of customs clearance services to take the stress out of clearing your goods. We’ll assign you a dedicated customs agent who will keep updated on regulation changes to ensure your shipment is completed according to current law and as efficiently as possible. We’re also AEO certified by HMRC for extra peace of mind.

Partnering with Clarksons removes the risk of underpaying Customs Duty and VAT. Our Duty Deferment Account means that, in many cases, these can be paid directly on import, helping you avoid potential fines and additional charges at a later stage. Similarly, choosing us as your customs broker will help avoid or reduce delays during clearance. Goods cannot be released until all Duty and VAT is paid and accurate documentation is submitted so, by allowing us to take care of this, you’ll minimise disruption and keep your business moving.
