Can drones or radios be imported into Sri Lanka?

Yes, but only with prior permission from the Telecommunication Regulatory Commission (TRC) and the Ministry of Defence. For drones, contacts: +94112430860/69, email webinfo@defence.lk, website www.trc.gov.lk. Without permission, equipment may be confiscated. The processing may take time, so start it well in advance of your trip.
