The FAR CUI Rule Is Back for Comment — What Changed and Why the 72-Hour Clock Matters

On June 23, 2026, the FAR Council reissued its proposed FAR CUI rule under a new docket, FAR Case 2026-001, reopening it for public comment through July 23, 2026. Here is what changed since the January 2025 draft — a longer incident-reporting window, a shift toward NIST SP 800-171 Rev. 3, a deleted clause, and a new conflict-of-law notice — and what a contractor should do with a proposed rule versus a final one.
