the food safety label is QS.

since June 1, 2111, the QS logo has been replaced with new styles. This change is mainly due to the change in the Chinese characters of the logo. The words "quality and safety" under the original QS logo have been changed to "production license".

"production license" must be marked below QS. The original QS logo is an access sign of food market, which consists of the initials "QS" and "quality and safety" in English. Enterprises that have not obtained the relevant production license cannot produce food, that is, they cannot use this logo.

the main color of the original QS logo is blue, the four Chinese characters "Q" and "Quality and Safety" are blue, and the letter "S" is white. The symbol of the enterprise food production license to be replaced is expressed by the pinyin abbreviation "QS" of "enterprise food production license" and marked with the words "production license" in Chinese.

food production license:

the food production license shall be issued by the food and drug supervision and administration department of the local people's government at or above the county level to the food production and business license institution according to law.
