First, the food hygiene license is divided into two types: large certificate and small certificate. The large certificate is issued as a legal person, and the small certificate (including temporary hygiene license) is issued by units and individuals who do not have the legal person qualification and are temporarily engaged in food production and operation. The certificate is valid for four years and is verified once a year. Submit an application for verification to the issuing authority within 30 days before the expiration of the annual period. Upon acceptance, the issuing authority shall affix the seal of "verified" on the original and photocopy respectively, and affix the seal of the administrative department of health to be valid, and issue a new certificate four years later. The certificate is valid for one year and does not need to be verified every year. Apply for renewal within 30 days before the expiration of the validity period, and issue a new certificate every year; The validity period of the temporary hygiene license is not more than half a year, and it is necessary to renew the hygiene license. Apply for renewal within 30 days before the expiration of the validity period, and then renew the health permit valid for one year or four years.

Second, there is no charge for the annual examination of food hygiene licenses.
