I am going to buy some products from a vendor that uses Pigeon Express to ship. Would I have to pay import duty on the items I purchase?
This is a matter that you will have to discuss with the vendor. It depends on the type of commodity you are purchasing, the value of the goods, how the vendor labels them for customs purposes and from what country you are importing them. If customs imposes a charge Pigeon Express will pay this at first instance, but you are advised to pay this, whether or not you accept delivery of the goods.
