If the expiration dates on shelf-life items are 3Q20, 06/2013, and 11/2015, which date should be marked on the CASKO?

To determine the correct date to mark on the CASKO, it is important to understand the concept of shelf-life and expiration in the context of the DoD Shelf-Life Program. Shelf-life items have specific expiration dates that indicate when they are no longer guaranteed to be effective or safe for use.

Among the given dates, 3Q20 represents a future date in the third quarter of the year 2020. This means that the items marked with this expiration date are still within their shelf life and can be considered valid for use. The other two dates, 06/2013 and 11/2015, indicate past expiration dates. These items have already exceeded their respective shelf lives, and thus, they are no longer suitable for use.

The correct mark for the CASKO should be the most current expiration date that is still valid. Since 3Q20 is the most recent future date, it would logically be considered the correct choice for marking, while the past dates do not apply since they indicate expired items. Therefore, the correct process involves marking the CASKO with the date that accurately reflects items that are still valid for consumption or use.
