When creating classified material, what must derivative classifiers ensure?

Derivative classifiers must ensure that the classified material they create adheres to the original classification markings. This means that when they develop new material based on previously classified information, they must accurately reflect the classification level and markings set forth by the original classification authority. This adherence maintains the integrity and security of classified information and ensures that the protections assigned to it are properly conveyed.

Maintaining the original classification markings helps prevent unauthorized disclosure and ensures that all employees handling the information are aware of its classification level and the implications it carries for handling, storage, and sharing. This process is essential for upholding the overall security framework governing sensitive information.
