Why are there no qs marks on many food packaging bags?bag in box 3L,5L,10L

　　The food is not subject to the management of QS certification, so there is no QS mark on the package. Only 15 kinds of food, such as wheat flour, rice, edible vegetable oil, soy sauce, vinegar, meat products, dairy products, beverages, condiments (sugar, MSG), instant noodles, biscuits, cans, frozen drinks, quick-frozen noodles and rice food, puffed food, have the QS mark.

　　The QS logo is the abbreviation of "Qiyeshipin Shengchanxuke", the enterprise food production license, marked with "production license".

　　The main color of the QS logo is blue, the four Chinese characters "Q" and "Production License" are blue, and the letter "S" is white.

　　QS is not a certification mark, but a production license mark. The implementation of production license is not only for food, but also for others.

　　Relevant knowledge development:

　　S It consists of the prefix "Qiyeshipin Shengchanxuke" (QS) and the Chinese character "Production License". The main color of the sign is blue, and the four Chinese words "Q" and "Production License" are blue; The letter "S" is white

　　On October 1, 2015, the new food production license management measures began to be implemented. The QS food production license number used previously was replaced by the SC food production license. The SC license did not print a huge "QS" on the outer package like the QS license, but would print a series of production license numbers beginning with SC on the package.

　　In addition, since the old QS certificates are valid for three years, all QS certificates have expired by September 30, 2018. That is, if it is found that there is a QS license for food on the market, but the production date is after September 30, 2018, the product can be regarded as unqualified product or unlicensed product.
