The Federal CUI mandate (in accordance with Executive Order (E.O.) 13556), was established in order to create a common marking framework across the Federal government for sensitive unclassified information created by or controlled by the Federal government.  This mandate was implemented in DoD by DoD Instruction 5200.48, Controlled Unclassified Information (CUI), effective March 6, 2020.

DoDI 5200.48 requires that all CUI will include the marking “CUI” on the top and bottom of every page.   Documents will also include a new CUI Designation Indicator box on the bottom right of the cover with information on who marked the document as CUI and why.  The CUI reasons, called “Categories” are listed at: https://www.dodcui.mil/CUI-Categories-and-Abbreviations/.

Controlled Technical Information (CTI) is one of the CUI Categories.   It is scientific and technical information, which is unclassified and not public.  For a number of reasons, including the unique requirements for dissemination of scientific and technical information, and the long history of already using distribution statements for decades for this purpose, it was agreed that for marking CTI will include using distribution statements.  

Markings for CTI:  Place "CUI" in the header and footer of each page, and have the CUI designation indicator block on the right bottom of the cover, and then include the full distribution statement as secondary distribution instructions.  Information on how to mark items that contain both classified and CUI information is available at the DoD CUI training site: https://www.dodcui.mil/Training/.
