Hello @jjb,
First of all thank you for your interest in SLIMBOOK.

The purchase process from countries outside the European Union is similar, when processing the purchase you will see that the price of the computer varies (after deducting the taxes that do not apply to exports outside the EU), although depending on the customs of the country it is possible that according to their regulations, apply their own taxes on the arrival of this material to your country.

This tax is collected by the transport agency that act as collection agent for the customs of the countries (they also charge a small percentage of expenses for this management).

Your customs office can give you more information about the taxes added to this type of purchases.

Best regards and I hope I have helped you!
