18 May 2026

Nemak S.A.B de C.V has achieved ASI Chain of Custody (CoC) Standard V2 (2022) Certification for the manufacturing and associated supply chain activities at their Nemak México S.A. facilities including Plants 1 & 2, Plants 3 & 4, Plants 5 & 6, PDC, HPDC, Machining and EMC. The Certification encompasses production processes, operational activities, and supply chain management for high-quality aluminium components for the automotive industry.

Aluminium Stewardship Initiative (ASI) today announced that Nemak México S.A. has been certified against the ASI Chain of Custody Standard V2 (2022). The Certification applies to multiple manufacturing facilities located in García, Nuevo León, including Plants 1 & 2, Plants 3 & 4, Plants 5 & 6, the Product Development Centre (PDC), High-Pressure Die Casting plant (HPDC), the Machining Plant, the Electric Mobility Centre (EMC), and the Melting Centre. These facilities manufacture aluminium automotive components such as engine blocks, structural components, and battery trays, with activities including aluminium melting, high-pressure die casting, machining, product development, and electric mobility manufacturing operations.

The ASI CoC Standard V2 sets out requirements for the creation of a Chain of Custody for material that is produced and processed through the value chain into diverse downstream sectors. The implementation of ASI’s CoC Standard links verified practices at successive steps of the supply chain – certified under the ASI Performance Standard – to the materials produced by ASI Certified Entities. The CoC Standard also confirms that appropriate policies and due diligence processes are in place to identify and address critical issues, such as corruption, human rights abuses, materials originating from conflict-affected and high-risk areas in the supply chain and support responsible sourcing.

The independent, third-party audit of Nemak México S.A. was carried out by DNV Business Assurance Services UK Ltd. A full listing of audit findings outlining evidence of conformances is available from page 5 of the summary audit report, linked below. No non-conformances were identified during the Chain of Custody Certification audit.
