Generally, the import of second-hand machinery has to go through intermediate inspection or commodity inspection, and the certificates are different. So it depends on the detailed information of your machine, and the process is the same. Generally, you prepare the information, put it on record, and then export it abroad and transport it. If you have to pass the intermediate inspection, it depends on which country you are from. It is usually shipped to Hong Kong, but this is uncertain. After intermediate inspection, it will be shipped to China.
