15 C.F.R. § 791.316
(a) When issued.
(1) BIS may issue an initial finding of violation that identifies a violation if BIS:
(2) Deadline for response; default determination. A response to an initial finding of violation must be made within 30 days as set forth in paragraphs (b)(2)(i) and (ii) of this section. The failure to submit a response within 30 days shall be deemed to be a waiver of the right to respond, and the initial finding of violation will become final and will constitute final agency action. The violator may seek judicial review of that final agency action in Federal district court.
