7 U.S. Code § 1638b - Enforcement
If the Secretary determines that a retailer or person engaged in the business of supplying a covered commodity to a retailer is in violation of section 1638a of this title, the Secretary shall—
(1) notify the retailer  of the determination of the Secretary; and
If, on completion of the 30-day period described in subsection (a)(2), the Secretary determines that the retailer or person engaged in the business of supplying a covered commodity to a retailer has—
(1) not made a good faith effort to comply with section 1638a of this title, and
(2) continues to willfully violate section 1638a of this title with respect to the violation about which the retailer or person received notification under subsection (a)(1),
after providing notice and an opportunity for a hearing before the Secretary with respect to the violation, the Secretary may fine the retailer or person in an amount of not more than $1,000 for each violation.
 So in original. Probably should be “retailer or person”.

2008—Pub. L. 110–246, § 11002(3), redesignatedsubsec. (b) as (a) and substituted “retailer or person engaged in the business of supplying a covered commodity to a retailer” for “retailer” in introductory provisions, added subsec. (b), and struck out former subsecs. (a) and (c) which related to applicability of section 1636b of this title to a violation of this subchapter and fine for violation of section 1638a of this title. The substitution in subsec. (a) was made for “retailer” the first time appearing to reflect the probable intent of Congress.
