As of 2017, the International Trademark Classification*** includes 45 categories, including 34 categories of goods and 11 categories of services. It contains more than 10,000 goods and services.

The difference is that members of the Nice Union can participate in the revision of the classification list, while non-member states have no right to participate.

The Nice Classification consists of two parts, one is a classification of goods and services arranged by category, and the other is a classification of goods and services arranged in alphabetical order.

Finally, it lists all the goods or services included in this category. Each product or Services have a sequence number for easy retrieval. In addition, each category has an annotation, which explains what products this category mainly includes, how this category is distinguished from related categories of products, and how to classify marginal products. This annotation is very helpful in classifying some easily confused products. .

The other section is an alphabetical list of goods and services.

The World Intellectual Property Organization publishes a classification table of goods and services arranged in English and French. The Chinese trademark authority has also compiled and printed a classification table of goods and services arranged in Chinese pinyin order. Using this table to look up general product categories is as easy as looking up a dictionary.
