Some countries require additional documentations for customs and clearance and if those are not provided to at the time of the order this might lead to the order being delayed. For instance Customers in the State of Qatar require a scanned copy of their National ID to be submitted with their order, and this can be uploaded after placing an order under the My Account Page. 

Customers will be prompted at the time of placing an order to upload any required additional documents. Orders destined for Qatar that so not have the National ID will not be shipped as they will not be allowed into the country without the proper documentation.
