The batch number of the product shown below is A8 1, which represents the August production of 202 1. TF lipstick mainly depends on the production batch number on the package to see the production date.

The base batch number of TF lipstick consists of three digits, and the first digit can generally be ignored, because it is the production batch number, which has nothing to do with the production date and has no special meaning, and can be viewed directly from the second digit. The second digit is generally the number 1-9 and the letters A, B, C*** 12, corresponding to 1-65438+ February respectively, where A is 10 and B is1/kloc-0.

The third digit is also a number ranging from 0-9 to * * * 10. For example, 0 means 2020, 1 means 202 1, 8 means 20 18, 9 means 20 19, and so on. Some people may say that 9 does not represent 2009. Obviously, manufacturers will not sell 609.
