The United Kingdom has left the EU on 31.12.2020. That means you will now be ordering as a customer of a so-called „Third-party country“.
Will my shipping costs increase?
Good news first: Fedex and DHL have not increased shipping costs so there is nothing which will change when ordering!
Are there any custom charges?
There is nothing you will be charged from our side. We will always declare your items as „collections and collector's pieces of ... historical interest". According to www.trade-tariff.service.gov.uk there will be 0% "Third-country duty" import charges to pay. By experience, a charge of VAT will depend on the invoice total as well as on the customs agent in charge.
