A trademark is a symbol to distinguish the source of goods or services, and each registered trademark is designated for a certain kind of goods or services.

It is precisely for the needs of trademark retrieval, examination and management that some goods with the same attributes are grouped into one category, and all goods and services are divided into 45 categories, forming a trademark classification table-the Classification Table of Goods and Services for Trademark Registration.

The development process of trademark classification;

In the past, the trademark authorities of various countries formulated their own commodity classification tables according to their national conditions and their understanding of commodities, which were used by the trademark authorities and trademark registration applicants. The commodity classification table is not static.

It will be gradually increased and revised with the richness of commodities and people's understanding of commodities. Since 1923, China has formulated and published five commodity classification tables. By the 1950s, the world economy had developed greatly and international exchanges were more frequent.

Some countries believe that the use of their own commodity classification tables can no longer adapt to the international convergence of trademark affairs, which brings trouble to the registration of trademark owners abroad and is not conducive to the development of trademark cause and economy.

The trademark authorities in these countries believe that trademark registration needs an internationally unified commodity classification table. In this case, the Nice Agreement came into being.
