You can complain to the industrial and commercial administration department.
No nameplate is a three-no product and is not a legal concept. It has now become a relatively popular term. Generally means there is no production date, no quality certificate (or production license) and no name of the manufacturer. There is also a saying that: three-no products are products without a production factory name, two production sites, and three no production health license codes. It is also said that there is no factory name, no address, and no trademark. General laws stipulate that there must be a Chinese factory name, Chinese factory address, phone number, etc. Anything missing will be regarded as an unqualified product. Any product that lacks one of the above requirements can be regarded as a "three-no product".
