Generally speaking, different subcategories under the same major category do not interfere with each other. That is to say, if the subcategories in the same major category are different, the same name can be registered. In this case, it is generally necessary to rule out whether similar products are involved in these several sub-categories. If similar products are involved, you need to make a careful judgment. It may be judged as the same category and the registration will not be possible. But as you said, these two sub-categories do not have similar services, so there is no relationship. However, you should also note that generally speaking, when someone registers for Category 43, they basically need to register for the catering category. You can see if his name has been rejected in the catering sub-category, so as to better judge the registration risk.
