What is the difference between chemical logistics and general logistics? Is it special?

Chemical logistics is special, because most chemicals are dangerous, flammable and explosive. This kind of vehicles should be transported in accordance with the regulations, and they need to apply for a dangerous goods transport license. Vehicles should be hung with dangerous goods signs, and drivers and escorts with dangerous goods transport qualification certificates should transport them at the same time. Some places have regulations on the control and restriction of dangerous goods transportation, which require special registration permission. There are large and small chemical logistics companies all over the country, and most of them will publish empty car information, find transportation sources, inquire about local transportation policies, and purchase transportation insurance on dangerous escort agencies.
