The International Classification of Goods and Services for Trademark Registration has 45 categories, including 34 categories of goods and 11 categories of services. Designation of trademarks used in commodities as commodity trademarks and designation of trademarks used in services as service trademarks. According to Article 18 of the Trademark Law: "When foreigners or foreign enterprises apply for trademark registration and handle other trademark matters in China, they shall entrust an organization recognized by the state with the qualification of trademark agency." This is a compulsory principal-agent principle adopted by foreigners and foreign enterprises in applying for trademark registration in line with international practice. In the past, only a few foreign-related trademark agencies designated by the state could act as agents for foreigners and foreign enterprises to apply for trademark registration or handle other trademark matters in China. However, from March 11, 1995, all the trademark agencies recognized by the state with trademark agency qualifications can carry out foreign-related trademark agency business.
