Responsible sourcing


The LME has introduced responsible sourcing requirements for all brands listed for good delivery on the LME. 

In October 2019, the LME announced its responsible sourcing requirements following a formal market-wide consultation on proposals underpinned by the Organisation for Economic Co-operation and Development (OECD) Due Diligence Guidance.

The LME’s requirements, which will apply to all its listed brands, rest on four core principles: the combination of transparency and standards; non-discrimination between large-scale mining (LSM) and artisanal / small-scale mining (ASM); adherence to well-established work in the sector; and a pragmatic and clear process.
