31 C.F.R. §§ 802.1106–802.1108

If the Staff Chairperson determines that extraordinary circumstances relating to national security warrant, the Staff Chairperson may waive the filing fee in whole or in part and will notify the parties in writing. No waiver shall be implied, even where the Staff Chairperson does not reject a voluntary notice under § 802.1108 for failure to pay the required filing fee.

The parties to a transaction shall not be required to pay an additional filing fee in the event that the Staff Chairperson permits the parties to withdraw and refile a notice under § 802.509(c)(2), unless the Staff Chairperson determines that a material change to the transaction has occurred, or a material inaccuracy or omission was made by the parties in information provided to the Committee, that requires the Committee to consider new information, in which case the Staff Chairperson will inform the parties in writing.

The Staff Chairperson may reject a voluntary notice under § 802.504(a)(3) upon a determination that the amount of the filing fee paid by the parties was insufficient under this subpart. Prior to rejecting a notice under § 802.504(a)(3), the Staff Chairperson shall inform the parties in writing of the insufficiency of payment and provide the parties three business days to pay the remainder of the filing fee. If the Staff Chairperson does not reject a voluntary notice under § 802.504(a)(3) upon a determination that the amount of the filing fee payment paid by the parties was insufficient under this section, the balance of the fee remains payable unless the Staff Chairperson notifies the parties in writing that the payment has been waived in whole or in part.
