Your company Mandoob should be able to sort out a import license though i have not heard of any new change to qatar import regulation ;)

Also try & assign your shipmnt to a clearing agents ( aramex or any local agent ) who will need to run-around at customs office to clear shipments for which you will need to give him $$.

Also customs u may have to pay.
