40 CFR § 174.21 - General qualifications for exemptions.
A plant-incorporated protectant is exempt from the requirements of FIFRA, other than the requirements of § 174.71, if it meets the exemption criteria in paragraphs (a) through (d) of this section.

(b) When the plant-incorporated protectant is intended to be produced and used in a crop used as food, the residues of the active ingredient of the plant-incorporated protectant are either exempted from the requirement of a tolerance under FFDCA (21 U.S.C. 321 et seq.) as listed in subpart W of this part, or no tolerance would otherwise be required.
(c) Any inert ingredient that is part of the plant-incorporated protectant is listed as an approved inert ingredient in subpart X of this part.
