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 trademark goods or services into classes most appropriate to their business.
TM Class 30 includes coffee, tea, cocoa and artificial coffee; rice; tapioca and sago; flour and preparations made from cereals; bread, pastry and confectionery; ices; sugar, honey, treacle; yeast, baking-powder; salt; mustard; vinegar, sauces (condiments); spices; ice.

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 30 may register in these other classes too.
If you are not sure while choosing Class 30 for your product, you also consider the following “Related Classes”: Class 5- Pharmaceuticals, Class 1- Chemicals, Class 29- Meat, Fish, Poultry, Class 31- Grains, Agriculture, Class 33- Alcoholic Beverages, Class 32- Beers and Beverages, Class 43- Food Services, Class 42- Science and Technology Services and Class 35- Advertising and Business 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.
