• That the copper in a specific finished product came from an awarded site, unless supply-chain traceability is separately documented.
• Low-carbon copper claims — the assessment covers responsible production practices, not carbon intensity.
• Company-wide claims — the award applies to the assessed site only.

• Has Responsible Material Sourcing Certification →

Expiry matters — check the certificate is current.

The Copper Mark is awarded per site and requires re-assessment on a set cycle — check the award is current.

The programme has expanded to related metals (e.g. zinc, nickel, molybdenum) under equivalent marks; confirm which metal and site the award covers.
