14 CFR §435.7

1. (a)A payload reentry determination is required to transport a payload to Earth on a reentry vehicle unless the proposed payload is exempt from payload review.
2. (b)A payload reentry determination made under a previous license application under this subchapter may satisfy the requirements of paragraph (a) of this section.
3. (c)The FAA conducts a review, as described in subpart D of this part, to make a payload reentry determination. Either a reentry license applicant or a payload owner or operator may request a review of the proposed payload using the application procedures contained in part 413 of this subchapter. Upon receipt of an application, the FAA may conduct a payload reentry review independently of a reentry license application.
