Submit a Tip

CFIUS reviews certain transactions that were not voluntarily filed and therefore did not receive safe harbor under section 721 of the Defense Production Act. If CFIUS determines a non-notified transaction may fall within its jurisdiction and raise national security concerns, Treasury may contact the parties for information and may request a filing.

How Non-Notified Cases Are Identified

CFIUS uses multiple sources to identify transactions that may warrant review, including:

  • Public tips and referrals
  • Executive branch and congressional referrals
  • Media and commercial data sources
  • Other government reporting channels

The Committee screens a large volume of potential transactions each year and requests additional information in a subset of matters.

What Happens Next

When CFIUS determines a non-notified transaction may be covered and raise national security considerations, it may:

  • Request information from the transaction parties
  • Request a notice or declaration filing
  • Initiate further review and, where warranted, require mitigation measures

Tips and Referrals

Members of the public may submit tips, referrals, or voluntary self-disclosures related to potential non-notified matters or mitigation concerns:
