When packaging is used for classified items, what is required?

When packaging is used for classified items, it is essential that the packaging is marked with classification information. This requirement ensures that anyone handling or transporting the classified material is aware of its sensitive nature. Properly marking the packaging with classification levels, such as "Confidential," "Secret," or "Top Secret," serves as a precautionary measure to prevent unauthorized access and to ensure that the materials are handled according to established security protocols.

Marking the packaging conveys critical information about the handling and protection of the contents within, facilitating appropriate safeguarding measures and reminding individuals involved in the mailing or storage of these items of their classified status. This practice is integral to maintaining information security and adhering to regulations that govern the management of classified materials.
