What do you think of shampoo number?

"Hygiene license number: XXXXX (No.)" or "Production license number: XXXXX (No.)". Shampoo number usually refers to the production license number (also known as hygiene license number, hygiene license number, relevant license number, etc. ). This number is issued by the relevant national regulatory authorities and identifies the license number of the product that can be sold in the market after it is legally approved and meets relevant standards. The production license number of shampoo is usually marked on the outer package or bottle body, which usually consists of two parts, namely "Hygiene license number: XXXXX (No.)" or "Production license number: XXXXX (No.)". Among them, the number before the number indicates the code of the issuing province (autonomous region or municipality directly under the Central Government), and the number after it is the specific number of the product.
