The reason will be due to your packages not having a merchant invoice in them. As such, we will require you to input the dollar value of your purchases for customs declaration purposes.
As the purchase was made by you, we trust that you will be able to provide an accurate input. Please note that we will need an accurate dollar value of the package for a smooth customs clearance. As such, you will need to input the actual value of the package regardless of whether it is a free gift from the merchant or as a gift for your loved ones and friends.
