Hello, I'm glad to answer your questions. The result I got here is that if you sell homemade bulk food, you need to apply for a health permit, a tax registration certificate and a business license, and go to the local health and epidemic prevention station to handle it with the tax bureau and the administration for industry and commerce.
If you purchase goods from a regular food company, you need to apply for a hygiene license, a tax registration certificate, a business license, and your health certificate. In addition, you should ask the supplier for a test report from the regulatory authorities once a year.
