Marking and selling labels are two different concepts:

Marking refers to marking on products during the production process of the enterprise according to relevant national regulations or the enterprise’s own management needs. Add text, pictures and other identifications, such as production date, expiration date, product number, etc.

Selling mark refers to a big brand selling its trademark to a factory or other company, allowing the products produced by it to bear the brand's logo. This is a selling mark. For example, the brand Antarctic has many products that sell well.

The above content is only a simple explanation. In the actual production process, it is necessary to decide how to operate according to the specific situation.
