All import taxes are included in your payment and there would be no further charges on receiving the order in the EU and the UK.
For all other countries that incur import fees, unfortunately, Comfort Works is not responsible for any custom taxes or import fee associated to the delivery of your order, nor can we guarantee the amount of taxes you have to pay.
Custom taxes or import fees will solely depend on the regulations of the country of importation, the total amount paid during check-out only accounts for the product value and shipping fee.
The best way to find out if you have to pay for them is by giving your local customs office a call and clarify with them before you order.
When still in doubt, do drop us a note and we'll help you the best we can!
