ASI certifies Impol – TLM d.o.o. against Performance Standard V3.1

18 September 2025

Impol – TLM d.o.o. has achieved ASI Performance Standard V3.1 (2023) for the design and production of rolled semi-finished Aluminium alloy products including slabs, sheets, strips, circles, and plain foils at their Impol – TLM d.o.o. plant in Šibenik, Croatia.

Aluminium Stewardship Initiative (ASI) today announced that Impol – TLM d.o.o., a subsidiary of the Impol Group, has been certified against the ASI Performance Standard V3.1 (2023). The facility is engaged in the production and processing of aluminium products, including the rolling and manufacturing of aluminium sheets, coils and foils for industries such as automotive, construction, packaging and aerospace. The site also has casting capacities enabling the production of aluminium slabs.

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 Impol – TLM d.o.o. was carried out by Bureau Veritas Certification. A full listing of audit findings is available in the summary audit reports, linked below. One minor non-conformance was noted under Criterion 4.3a-b Aluminium Process Scrap. Impol – TLM d.o.o. will be implementing corrective actions, to be verified in a follow-up audit.
