ASI certifies Independent Extrusions Ltd against Performance Standard V3.1

9 June 2026

Independent Extrusions Ltd has achieved ASI Performance Standard V3.1 (2023) for the extrusion, warehousing and distribution of aluminium products and services at their operations located in Hamilton, New Zealand.

Aluminium Stewardship Initiative (ASI) today announced that Independent Extrusions Ltd has been certified against the ASI Performance Standard V3.1 (2023). The facility extrudes and supplies aluminium profiles for the building, construction, and original equipment manufacturer (OEM) sectors, using aluminium extrusion processes operated across two extrusion presses with a combined production capacity of approximately 18,000 tonnes per annum.

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 V3 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 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 Independent Extrusions Ltd was carried out by Sustainable Certification Pty Ltd. A full listing of audit findings is available in the summary audit reports, linked below.
