They are not. Unfortunately, we do not have a say on customs and duties fees. All Customs and Duties Fees are the responsibility of the customer to be paid upon receipt of package. The amount varies from country to country and depending on item(s) ordered.
And if the order was refused to accept due to custom fees, the package might be destoryed and can not be delivered again. In this case, the refund will not be refunded. So we suggest that customer could check the local custom policy first before placing the order.
