Differences:
1. The applicant for certification of a trademark is an institution or association with supervisory ability; The applicants for collective trademarks are general groups and collectives.
2. Certification trademarks are generally used directly in economic activities; Collective trademarks are only used by collective members.
3. The applicant who proves the trademark owns the trademark, but has no right to use it; Members of a collective trademark have the ownership and right to use the trademark.
4. Some collective trademarks are also used in economic activities, such as the logo of the Olympic Committee and the logo of the basketball association.
It is enough to understand the latter case:
The certification trademark is "Green Food", which was applied for registration by China Green Food Development Center.
collective trademark: "Nanhai Jinsha Hardware", the first case of collective trademark in hardware industry, was applied by Nanhai Hardware Industry Association of Foshan City.
