Aluminium Stewardship Initiative certifies Jiangsu Zhongji Lamination Materials Co., Ltd, against ASI Chain of Custody Standard

Jiangsu Zhongji Lamination Materials Co., Ltd, has achieved Certification to the ASI Chain of Custody for its facility in Jiangyin City, China. The certification includes post-casthouse activities related to their aluminium foil production.

Aluminium Stewardship Initiative (ASI) today announced that Jiangsu Zhongji Lamination Materials Co., Ltd, facility for aluminium foil production has been successfully certified against ASI’s Chain of Custody Standard. The same facility was also recently certified to the ASI Performance Standard.

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 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 independent, third-party audit of Jiangsu Zhongji was carried out by DNV GL.

Fiona Solomon, Chief Executive Officer at ASI, said “Warm congratulations to Jiangsu Zhongji for achieving CoC Certification soon after their Performance Standard Certification last month. The commitment of foil suppliers to ASI supports the focus on sustainability and responsible sourcing by downstream customers in the packaging sector and other foil-using sectors.”

Zhu Hongyu, general manager of Jiangsu Zhongji Company, said, “We are very happy to pass the ASI CoC Certification, and we are very grateful for the management of DNV and ASI that strongly supported us during the certification process. In the future, we will continue to support ASI.”

ASI Certification process
ASI’s Standards apply throughout the supply chain, from mining through to downstream sectors that use aluminium in their products. All current ASI members in the ‘Production and Transformation’ and ‘Industrial Users’ classes will be working towards their own ASI certifications in the coming two years. ASI Members are listed at

ASI’s custom-built online assurance platform, elementAl underpins the entire certification workflow for both the ASI Performance Standard and Chain of Custody Standard. First, elementAl’s user-oriented interface and workflows support the prospective company during the initial self-assessment phase and data is protected by a secure firewall. With a click, the company can make their relevant elementAl information accessible to their chosen auditor.

Auditors use elementAl to support audit planning, on-site verification and reporting. ASI reviews submitted audit reports for conformity with ASI’s assurance procedures as a final control, before the certification approval and certificate(s) are issued. Full ASI certification is valid for three years, usually with a surveillance audit at approximately 18 months.
