ASI certifies Sichuan Wanshun Zhongji Aluminum Co., Ltd. against Performance Standard V3.1 and Chain of Custody V2
The facility operates casting, rolling, cold rolling, and annealing processes to produce aluminium foil blanks.
2 January 2026
Aluminium Stewardship Initiative (ASI) today announced that Sichuan Wanshun Zhongji Aluminum Co., Ltd. has been certified against the ASI Performance Standard V3.1 and Chain of Custody Standard V2. The facility operates casting, rolling, cold rolling, and annealing processes to produce aluminium foil blanks, with an annual output of approximately 50,000 tonnes of double zero aluminium foil blanks and 80,000 tonnes of aluminium foil blanks for lithium battery cathodes, supported by multiple production lines, annealing furnaces, grinding equipment, and auxiliary facilities.
The ASI Certification program was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The ASI Performance Standard V3 and ASI CoC Standard V2 were launched in May 2022 following a multi-year revision process. The 2022 Standards and related documents underwent a minor update in 2023, accounting for editorial changes, correction of minor errors and for general clarification, culminating in the release of Performance Standard V3.1 (2023) and Chain of Custody Standard V2.1 (2023).
The ASI Performance Standard defines 11 principles and 62 criteria under three sustainability pillars – Environment, Social, and Governance – with the aim to address pressing sustainability issues in the aluminium value chain, such as biodiversity, Indigenous Peoples rights, circularity, and greenhouse gas emissions. The ASI CoC Standard 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 products 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.
