DoD, GSA, and NASA are proposing to amend the Federal Acquisition Regulation (FAR) to implement the National Archives and Records Administration (NARA) Controlled Unclassified Information (CUI) program of Executive Order 13556 of November 4, 2010. As the executive agent designated to oversee the Governmentwide CUI program, NARA issued implementing regulations in late 2016 designed to address Federal agency policies for designating, safeguarding, disseminating, marking, decontrolling, and disposing of CUI. The NARA rule, which is codified at 32 CFR 2002, affects contractors that handle, possess, use, share, or receive CUI. This FAR rule helps to ensure uniform implementation of the requirements of the CUI program in contracts across Government agencies.
