29 CFR §810.500

Section 202A(e)(1) of the USMCA Implementation Act gives the Secretary, in conjunction with the Secretary of the Treasury, authority to verify whether a covered vehicle complied with the LVC requirements set forth in Article 7 of the Automotive Appendix, or if the producer is subject to the alternative staging regime, under Articles 7 and 8 of the Automotive Appendix. The Secretary's role in conducting verifications is limited to verifying compliance with the high-wage components of the LVC requirements. All matters other than the high-wage components of the LVC verification are outside of the Secretary's purview and are addressed in the Uniform Regulations and regulations and/or guidance issued by the Department of the Treasury, CBP, or other federal agencies.
