A carrier or broker covered by subchapter I, II, or III of chapter 135, or an officer, receiver, trustee, lessee, or employee of that carrier or broker, or another person the carrier or broker has authorized to receive its information, may not disclose to anyone besides the shipper or consignee -- and no one may solicit or receive -- information about the nature, kind, quantity, destination, consignee, or routing of property given to that carrier or broker for transportation under this part, without the shipper's or consignee's consent, if that information could be used to hurt the shipper or consignee, or could improperly reveal the shipper's or consignee's business to a competitor. (2) Penalty. A person who violates paragraph (1) is liable to the United States for a civil penalty of not more than $2,000. (b) Limitation on Statutory Construction.
