Within the EU there is no customs duty, as we ship from Sweden.
To Norway, the UK and Switzerland, customs duty and import VAT are included in the price. You pay nothing extra on delivery.
To other countries outside the EU, for example the US, your country's customs may charge duties and taxes when the parcel arrives. These are paid by you as the customer, and unfortunately we cannot predict the amount: it depends on your country's rules and the value of the order. If the parcel is refused at delivery because of customs charges, a handling fee applies.
