ASI Aluminium Stewardship Certificate

Facilities in the aluminium supply chain were independently audited against ASI's Performance Standard (environmental, social, and governance practices from bauxite mining through smelting and fabrication); an additional Chain of Custody certificate allows material produced through certified facilities to be sold as ASI Aluminium.

• That the aluminium in a specific product is low-carbon — Performance Standard certification is not a carbon footprint claim.
• Recycled content claims — ASI certification is independent of recycled content percentage.
• Material-flow claims from a Performance Standard certificate alone — only Chain of Custody certification links certified facilities to the metal in a product.

Expiry matters — check the certificate is current.

Always distinguish the two ASI standards: Performance Standard certifies how facilities operate; Chain of Custody certifies where the metal flowed.

A supplier's ASI membership is not certification — check for an actual certificate and its scope.
