Why can I send a courier by mobile phone when I fly, but I can't send it by air?

Mobile phone batteries are flammable and explosive contraband, so you can't take air express.

In digital products such as mobile phones and cameras, lithium in batteries is an extremely unstable metal, and lithium batteries are prone to spark when they are rubbed or collided. If the lithium battery is directly put into the luggage, the luggage is easy to be squeezed or collided in the narrow cargo hold, which increases the risk factor of navigation.

Courier companies cannot transport electronic products by air, but only by land. Exports must also be transshipped from Hong Kong. Last year, a courier company illegally transported electronic products by air, which led to a fire in the cargo hold of the plane; So the State Post Bureau issued a ban. Before SF, mobile phones could be transported from Shenzhen to Chengdu by air, but now electronic products are land transportation and cars. Even foreign trade products can only choose the air transport channel in Hong Kong.
