I need to apply for QS certification. I also want to do so. I only made the plan for Lianzi. I have a classmate in the Quality Inspection Bureau, but she is in Beijing and has already consulted clearly. Strictly speaking, it is necessary unless You only sell in bulk in your shop, so you don’t need QS. Wherever you produce, you need to apply for the certificate. QS must come to inspect it, and it will randomly check your production address twice a year. It is not easy to do. Of course, you need someone to handle it. It may be easier to get a sales license in Shanghai and get a circulation license; Well, of course you have to print it on your own packaging bag. Trademarks are not necessarily related to this, but it is necessary to apply for a trademark to protect yourself, and it is also necessary if you want to grow bigger.
