Most countries use the CIF (Cost, Insurance, and Freight) method to calculate duty charges. CIF is a pricing term that means the cost of the goods, insurance and freight (shipping charge) are included in the quoted price. The total duty and tax charge is calculated by adding all costs together.
If a coupon is applied to an order, only the original listed price, before said coupon, will be used for the CIF.
We cannot change these amounts.
