the application for catering guarantee certificate should be submitted and applied to the environmental protection department and the industrial and commercial bureau. Take a small restaurant opened by individual industrial and commercial households as an example. The specific procedure is as follows: first, take the original and copy of your ID card to the local industrial and commercial office to register the name. Remember that this is just a name registration, and it is not time to apply for an industrial and commercial business license. Because before obtaining the industrial and commercial license, you must first apply to the environmental protection department and the health supervision office within your jurisdiction for the sewage discharge permit and health permit.
