The number of trademark registration categories is determined according to the International Classification (Nice Classification) system, which divides goods and services into different categories to facilitate the classification and management of trademarks. Currently, the international classification system is divided into 45 categories, of which 34 categories are used to classify goods and 11 categories are used to classify services.

The following are the main classifications of goods and services in the international classification system:

Commodity classification:

Category 1-34: Covers various commodity categories, including Chemical products, household products, mechanical equipment, electronic products, pharmaceutical products, transportation tools, etc.

Service classification:

Category 35-45: Mainly covers various service industries, including advertising, insurance, finance, construction, education, entertainment, catering, etc.

It should be noted that when registering a trademark, you need to select the applicable category to ensure that the scope of trademark protection matches the goods or services provided. There may be some minor differences or subcategories in different countries or regions, but generally follow the basic framework of the international classification system.
