The NICE Classification was established in 1957 by NICE Agreement, and it divides marks into 45 different classes by Goods and Services (Classes 1-34 for Goods and Classes 35-45 for Services). The purpose of these classifications is to allow users to seek to trademark a goods or services into classes most appropriate to their business.
TM Class 25 include clothing, footwear, and headgear.
You would not use Trademark Class 25 if you were registering for:
A related trademark class is one that is related to another class; this is due to the Indian Trademark Office (ITO) has determined that applicants registering within Class 25 may register in these other classes too.
If you are not sure while choosing Class 25 for your product, you also consider the following “Related Classes”: Class 14- Precious Metals, Class 19- Building Materials, Class 18- Leather Goods, Class 35- Advertising and Business Services, Class 24- Textiles and Class 42- Science and Technology Services.
Trademark Registration fees also vary on bases of the Class system. You must pay a separate registration fee for each class of goods and services that you want to register. For instance, if you are going to register a trademark for Chemicals in Class 1 and Rubber in Class 17, you should pay two separate fees.
It is necessary to choose the correct class at the time of registering a trademark, if you register a trademark in the wrong class, you must start the registration process from the beginning.
