the vehicle is imported for personal use, and not for resale, by an individual (except an individual described in sections 30143 and 30144 of this title); the vehicle is imported after January 31, 1990 ; and the individual takes the actions required under subsection (b) of this section to receive an exemption. an appropriate bond in an amount determined under section 30141(d) of this title ; a copy of an agreement with an importer registered under section 30141(c) of this title for bringing the motor vehicle into compliance with applicable motor vehicle safety standards prescribed under this chapter; and a certification that the vehicle meets the requirement of section 30141(a)(1)(A) or (B) of this title; and will be brought into compliance with those standards within a reasonable time (specified by the Secretary of Transportation) after the vehicle is imported; or will be exported (at no cost to the United States Government) by the Secretary of the Treasury or abandoned to the Government. For good cause shown, the Secretary of Transportation may allow an individual additional time, but not more than 30 days after the day on which the motor vehicle is offered for import, to comply with paragraph (1)(A)(ii) of this subsection.
