ASI certifies Sunho New Materials Technology Co., Ltd. against Performance Standard V3.1 and Chain of Custody V2
The facility produces double-zero aluminium foil and battery foil
3 September 2025
Aluminium Stewardship Initiative (ASI) today announced that Sunho New Materials Technology Co., Ltd. has been certified against the ASI Performance Standard V3.1 and Chain of Custody Standard V2. The facility has an annual production capacity of 115,000 tonnes of light gauge aluminium foil and battery foil. Its operations are supported by equipment including aluminium foil rolling mills, roll grinders, slitting machines, precision cutting machines, and annealing furnaces.
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 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 process 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 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 independent, third-party audit of the Sunho New Materials Technology Co., Ltd. facility was carried out by DNV Business Assurance Services UK Ltd. A full listing of audit findings outlining evidence of conformances and minor non-conformances is available from page 5 in each of the summary audit reports, linked below. Eight minor non-conformances were noted during the Performance Standard Certification audit, under Criteria 1.2 Anti-Corruption, 3.1a-b Sustainability Reporting, 4.1a Environmental Life Cycle Assessment, 4.4d Collection and Recycling of Products at End of Life, 5.1a-b Disclosure of GHG Emissions and Energy Use, 5.3a GHG Emissions Reduction Plans, 5.3b-e GHG Emissions Reduction Plans – Targets, review and disclosure, 9.8e Conflict-Affected and High-Risk Areas – Report annually, 10.8a-c Working Time and 11.1a Occupational Health and Safety (OH&S) Management System. One non-conformance was identified during the Chain of Custody Certification audit, under Criterion 7.2 Risk Assessment and Mitigation. During the Certification period, Sunho New Materials Technology Co., Ltd. will be implementing a corrective action plan, which will be verified in follow-up audits.
