Is “drone” a “flying camera” or an “aircraft with a camera”?

According to the Shenzhen Customs Tariff Department, if “drones” are classified as “aircraft with cameras”, they must be supervised as “aircraft”, so that the trade control conditions of various countries will be stricter, and it is easy to form non-tariff trade barriers; However, if it is classified as “flying camera”, it can be regulated as “camera”. Countries generally do not have special trade control requirements for cameras, which is conducive to the entry of high-tech superior products into the civilian market.
