We handle customs clearance 

Hubs handles customs for orders to/from the UK, US and countries within the EU. We ship Delivered Duty Paid (DDP), meaning that we handle customs before your part arrives at one of our cross-docking locations in Amsterdam or Chicago before shipping it to you.

Unfortunately, we can’t handle customs for every country and region. If your order originates from or is being shipped to a country outside the UK, US and EU, we won’t be able to handle customs directly. We can assist you with documentation and other types of support if need be.
