When shipping outside of the European Union DHL does sometimes charge an amount for VAT, even though sending via DHL will safe lots of money on import costs we do sometimes see that DHL charges an amount. We see this happen for the United Kingdom, Norway and for Iceland.
For every country that is part of the European Union we are obligated to charge VAT, but we do not charge VAT to countries that are not in the EU (Just like the countries mentioned above). Instead those countries choose to charge import tax which is an equivalent for the VAT that we charge within the EU. So those costs are usually an replacement for VAT.
Still have questions on possible shipping costs, feel free to reach out.
