Legal analysis
This depends on the specific situation to judge. If the source of the three-way catalytic converter is unknown or illegally obtained, it is illegal to resell the three-way catalytic converter, and it is likely to go to jail. If the route of the three-way catalytic converter is normal, it is not illegal and naturally there will be no consequences. It is necessary to know that as long as it is not a material monopolized by the state or prohibited by the state, there is no illegal behavior in individual trading. Obviously, the three-way catalytic converter is only the spare parts of vehicles, and it is not illegal to resell the spare parts of vehicles. So friends who want to do this business don't have to worry too much, just do it boldly. If it is not a state monopoly, private sales will generally not be illegal. For example, tobacco is a state monopoly, and it is not allowed to resell it privately, otherwise it will be suspected of smuggling. If it is some chemicals, biological agents, or drugs and medical devices used by people and animals, it needs qualifications to operate. It is illegal to operate without qualification, and whether it is a crime depends on the situation. If it is a general commodity, it needs a business license issued by the industrial and commercial tax department, and it can operate normally. Food also needs permission from health and food and drug supervision departments, otherwise it will face administrative punishment.
