49 U.S.C. § 30115 — Certification of compliance

A manufacturer or distributor of a motor vehicle or motor vehicle equipment shall certify to the distributor or dealer at delivery that the vehicle or equipment complies with applicable motor vehicle safety standards prescribed under this chapter. A person may not issue the certificate if, in exercising reasonable care, the person has reason to know the certificate is false or misleading in a material respect. Certification of a vehicle must be shown by a label or tag permanently fixed to the vehicle. Certification of equipment may be shown by a label or tag on the equipment or on the outside of the container in which the equipment is delivered.

In the case of the certification label affixed by an intermediate or final stage manufacturer of a motor vehicle built in more than 1 stage, each intermediate or final stage manufacturer shall certify with respect to each applicable Federal motor vehicle safety standard—

If the intermediate or final stage manufacturer elects to assume responsibility for compliance with the standard covered by the documentation provided by an incomplete motor vehicle manufacturer, the intermediate or final stage manufacturer shall notify the incomplete motor vehicle manufacturer in writing within a reasonable time of affixing the certification label. A violation of this subsection shall not be subject to a civil penalty under section 30165.
