It depends on which department manages the local geographical indication certification trademark.

If non-members of geographical indication certification trademarks (natural persons, legal persons or other organizations) want to use geographical indication trademarks, they only need to be able to prove that their products come from the designated production area and that the products comply with the geographical indication trademark. If the quality requirements are met, you can request to use the certification mark. At this time, you need to apply to join the geographical indication trademark user unit or apply to the local intellectual property management department (specifically, it depends on the local geographical indication trademark management situation). You can only use it after obtaining authorization. Unauthorized use is not allowed.
