Hello, I've done this permit before, first you need to provide a business license, then your technician, or the main operator's health certificate, and then also the photos of your operation site. The outer packaging photos. Set this time is that the Health Bureau will go to your site to take pictures, to check whether your site is clean, whether the operation is standardized. If it is a very high-risk industry, easy to cause disease, there will be on-site inspection, so there is this 20-day audit. This 20 days is not fixed, every city is different.

I hope I can help you, if the answer makes you satisfied, please give me a like, thank you!
