Trademark registration categories usually include the following aspects:

1. Product category: Trademark registration requires specifying the applicable product category. Goods categories are classified according to the nature and purpose of goods or services in order to manage and protect trademarks. The commodity classification system commonly used internationally is the "Nice Classification".

2. Service category: In addition to the product category, trademark registration also needs to specify the applicable service category. Service category refers to the industry or field served by the trademark and is used to distinguish different types of services. The classification system of service categories is also based on the "Nice Classification".

3. Subdivision of trademark categories: Goods and service categories are often further subdivided into different subcategories or groups of subcategories. These subdivisions can more accurately describe the specific goods or services to which the trademark applies.

The choice of trademark registration category has an important impact on the scope of trademark protection and rights and interests. Trademark applicants need to carefully select the applicable categories of goods and services and ensure that they are consistent with the actual use of the trademark or the scope of proposed registration.

Please note that different countries and regions may have slightly different trademark classification systems, but most countries refer to the Nice Classification as a benchmark.
