The difference between the two industry types is that the category content is different.

1. Category 35: Category 35 is not the main category of the catering industry. Category 35 is advertising, industrial operations, industrial management, and office affairs.

2. Class 43: When registering a trademark in the catering industry, you need to apply for Class 43 first. This is because Class 43 mainly includes the provision of food and beverage services and temporary accommodation, which is the basic category of the catering industry.
