If you're ordering from outside Pakistan, your country may charge import duties or taxes. These aren't included in your order total and are paid to your local customs or courier when your piece arrives. The amount is set by your country, not by us, so it varies by destination.
For orders to the UAE: shipments over AED 300 are charged customs duty and VAT of roughly 10 percent in total, collected by the courier at delivery. There is nothing else to pay.
