   Mexico to require prior permits for tariff-exempt auto parts imports

   From October 30, imports of vehicle assembly components under tariff code 9803.00.01 will require prior permits. The temporary tariff exemption, published October 13, aims to attract automotive production and strengthen regional supply chains.

   Context

   Mexico published a decree on October 13, 2026 that temporarily exempts parts and components for automobile assembly from import tariffs under tariff code 9803.00.01. That exemption supports automotive industry competitiveness and job creation.

   Why it matters

   Eligible vehicle assemblers will need permits for imports under either the definitive-import or fiscal-deposit regime. Approval requires a favorable opinion from the Economy Ministry's heavy-industry and high-technology office, plus proof of compliance with the ministry's guidelines.

   Mexico's Supreme Court orders end to hold on Nayarit pension-law rulings

   On August 17, the Supreme Court partially struck down Nayarit's 2023 pension law, including provisions covering private-sector and self-employed workers. A new order lifts the pause on rulings in related cases effective the day after publication.

   Context

   Nayarit published its retirement-savings-fund law on March 16, 2023. The Supreme Court's August 17, 2026 ruling upheld the legislative process and several provisions, while invalidating others.

   Why it matters

   Regional plenary courts and collegiate circuit courts must resolve the affected cases using the reasoning in the Supreme Court's ruling. The earlier order had allowed proceedings to continue but postponed the decisions. The new order removes that restriction the day after publication.
