Is it correct that classification markings should only be used when information is originally classified?

The assertion that classification markings should only be used when information is originally classified is inaccurate. Classification markings are not limited solely to information that is being classified for the first time. They are also applied to documents that have been classified previously and continue to require protection due to their sensitive nature.

Marking serves several purposes beyond the initial classification. It informs recipients of the handling and dissemination requirements associated with the information, ensuring that individuals understand the level of protection required for the material. This applies to documents that are upgraded from a lower classification, or documents that are declassified but still warrant specific markings during their transition to unclassified status. Consequently, classification markings are essential not just at the point of initial classification, but throughout the life cycle of classified information.
