To get a Drone permit in Tunisia you need to get the approval from three ministries (interior, defense and equipment (responsible of the airports)).
You need to send your request 03 months before your filming day, with a specification of the location, GPS coordinates and exact time.
Also a copy of the pilot permit and the synopsis of the movie or documentary you want to film. You need to do that whenever you use your drone.
If you are a Tunisian company you can get a permanent drone permit, renewed every month. You are simply requested to announce to the authorities when and where you will use the drone.
The importation of a drone to Tunisia is not allowed and the Tunisian customs services will detent it. You will get it back when you leave the country. If your exit airport is not the same one you used for your entry, you need to write a request to inform them, to ensure that they bring it to your exit airport on your leave.
If, for any reason, you can’t bring it back with you or you want someone else to bring it with them, you need to write a request to inform the customs services about that, specifying the person’s name and their passport number. In all cases, you need to inform the customs services by phone that you are leaving, 24h before your flight, so they can prepare it for you without any delay, on your flight day. You can ask for their number directly or by calling the airport or you cellphone operator.
