1. For selling self-made bulk food, you need to apply for hygiene license, tax registration certificate and business license, and go to the local health and epidemic prevention station, tax bureau and administration for industry and commerce. Taobao does not handle these certificates, but you can upload scanned copies. You'd better make a product inspection report of your products and your health certificate in the Bureau of Quality and Technical Supervision once a year. Do all the above, and you will have no problem selling bulk food anywhere.
