Do I need to leave the manufacturer's phone number for the second-class instrument box?
The secondary instrument box does not need the phone number of the manufacturer. According to the relevant public information, the packaging box of Class II devices needs to have "product name and specification" and the name of the article, and it needs to have a written description, indicating the sterility of the product, the production batch number or date, the expiration date, the name and address of the manufacturer, the product registration certificate number, the license number of the manufacturer, the implementation standard, etc. There is no requirement to leave the phone number of the manufacturer.
