Extended data
As a famous American brand, Estee Lauder usually marks the date of production on the bottom or body of the bottle. There are two commonly used coding forms, one is three-bit coding and the other is five-bit coding. The production date of the five-digit code is marked as follows:
The first one represents the place of origin, A America, B Britain, C Canada, I Italy, etc. The second represents the project number; The third digit represents the month, 1-9 represents1-September, and letters a, b and c represent 10,1,65438+February; The fourth digit represents the year and the digit represents the last digit of the year; The fifth digit represents the batch number.
Although the brand batch number is accurate to the month, it doesn't matter whether 1 or 3 1 expires, because the shelf life marked is definitely much shorter than the actual shelf life. Even if 1 expires, there is a 99% certainty that it will not deteriorate by 3 1.
