Parties to a transaction that choose to file notice of the transaction with CFIUS must do so in accordance with the procedures stated in the regulations at 31 C.F.R. § 800.501. The notice must include the information required in the regulations at 31 C.F.R. § 800.502.
1. Pre-Notice Consultations and Draft Notices
CFIUS does not issue advisory opinions as to whether a transaction might raise national security concerns or be considered a covered transaction subject to review. Parties to a transaction are encouraged to consult with CFIUS in advance of filing a notice and/or to file with CFIUS a draft notice or other appropriate documents describing the transaction. The notice must include the information required in the regulations at 31 C.F.R. § 800.502.
Such steps both aid the Committee’s understanding of the transaction and provide an opportunity for the Committee to request additional information to be included in the actual notice. Upon receiving the notice, the Staff Chairperson will promptly determine whether the notice satisfies the requirements for completeness as promulgated in the regulations. If the notice is complete, the Staff Chairperson will circulate the notice to all CFIUS members. A review period of up to 45 days begins on the next business day.
Any such pre-notice consultation should take place, or any draft notice should be provided, at least five (5) business days before the filing of a voluntary notice. All information and documentary material submitted or filed with the Committee as part of pre-notice consultations is accorded confidential treatment pursuant to 31 C.F.R. § 800.802 of the regulations.
2. Filing a Notice
Individual files submitted electronically must be no larger than five megabytes (5MB) in size to facilitate handling by CFIUS. Larger files must be broken down into multiple files of 5MB or less. Please also provide a hyperlink to any documents over 5MB that are publicly available on the Internet.

Hard copy notices are no longer required.

Required Contents of a Notice

Encryption and File Security
CFIUS supports efforts to help protect the security of sensitive data filed with CFIUS. File encryption is a useful tool to ensure that sensitive data remains secure. CFIUS can receive encrypted electronic filings and CFIUS recommends that filers use encryption whenever filing personal identifier information and other sensitive information with CFIUS. The instructions below explain how to submit encrypted files to CFIUS. You are responsible for appropriately encrypting your files.
Individual File Encryption: (a) Encrypt the file(s) using a strong password. CFIUS recommends that passwords contain a minimum of 12 characters and a combination of uppercase, lowercase, numbers, and non-alphanumeric characters. CFIUS cannot reset or recover lost passwords. You may use the guide for step-by-step instructions on encrypting Microsoft Office and Adobe Acrobat (.pdf) files. CFIUS can receive encrypted Microsoft Office and Adobe Acrobat (.pdf) files, and may be able to receive other file format encryption as well; please contact CFIUS for more information. (b) Submit the encrypted file(s) to CFIUS@treasury.gov. (c) Provide the password to the encrypted file(s) to CFIUS either by phone or through the Zix portal (see below). Passwords should never be sent to CFIUS in an unencrypted email.
Accessing the Zix Portal: (a) Send an email to CFIUS@treasury.gov requesting Zix secure email access. Do not attach any documents or include any sensitive information in this email. (b) CFIUS sends a response via email which will include instructions on activating and accessing the Zix portal. You must activate the portal within 15 days. (c) Once activated, the Zix portal can be used to send encrypted documents to CFIUS. Entire encrypted filings may be submitted via the Zix portal, or filers may use the Zix portal to submit the password for individual encrypted files submitted directly to CFIUS@treasury.gov.
3. Notice Timetable
See the CFIUS Overview page for a detailed description of the notice timetable.
Parties to a transaction that file a voluntary notice with CFIUS are required in every case to provide two types of certifications: A certification at the time of filing that covers the contents of the voluntary notice (31 C.F.R. § 800.502(l)) and a certification at the conclusion of a review or investigation covering all additional information filed subsequent to the original notice (31 C.F.R. § 800.502(m)).
The final certification will be requested several days before the end of the review or investigation and should be submitted at least one or two days before the anticipated closing date of the review or investigation. A review or investigation cannot be closed without the certification, and failure to provide a final certification by Day 45 of the review or Day 45 of the investigation is grounds for rejection of the notice.
The requirements for the certifications, including the contents and the person(s) who may sign the certification, are set forth at 31 C.F.R. § 800.204. Sample certifications are found below:
