(a) General. If the importer fails to comply with any requirement under this subpart, including submission of a complete supporting statement prepared in accordance with § 10.724 of this subpart, when requested, the port director may deny preferential treatment to the imported good.

(b) Failure to provide documentation regarding third country transportation.
