If the destination country is outside the European Economic Area (EEA), the customer would not have paid VAT to us during the order, i.e., they have paid less than someone within EEA.Please be advised that some countries have stringent customs rules and so items may not be released from customs until the charges are paid. Havox.com works to the DDU rule, whereby Delivery Duty is Unpaid by us. Therefore, any costs incurred during the customs clearance process would then need to be paid for by the recipient.Havox.com has no control over the amount of charges an item incurs as this is a customs process; therefore we would not be able to refund any payments back to you as we ultimately do not receive any of the charged amounts.**Please note that your Havox.com customs invoice will include the total value of the order, excluding offers or discounts. As such, you may be charged by customs based on these values.
