The following categories require trademark registration:

1. Branded watches: AliExpress is very strict about watch products, and only authorized sales of regular brands are allowed. Merchants must provide official authorization certificates and trademark registration certificates, otherwise they will not pass the platform review.

2. Baby and child products and toys: This is one of the most popular categories on AliExpress, involving children's safety and health issues, so the platform requires merchants to provide products that meet safety standards and trademark registration certificates. In addition, the pictures, descriptions, labels and other information of baby and child products must also comply with the relevant regulations of the platform.

3. Clothing, shoes, bags and jewelry accessories: These categories of products have a very large sales volume on AliExpress, but they are also strictly controlled by the platform. Merchants must provide products that meet quality standards, copyright protection and trademark registration requirements, otherwise they will not pass the review.

4. Home and Home Decoration: This category includes various daily necessities such as home accessories, furniture, kitchen supplies, bathroom equipment, etc. It is also a very popular category on AliExpress. However, the platform will strictly review the quality and safety of each product, and merchants need to provide products that meet the standards and trademark registration certificates before they can carry out business activities.
