The mica group represents 37 types of minerals, with layered structures that allow them to be split into thin flakes or sheets. Mica is largely known for its application in cosmetic products and paint. It is also used for insulation and heat resistance, and can by found in some components of electronic and automotive products.

In two major mica-producing countries, India and Madagascar, mica supply chains rely heavily on artisanal and small-scale extraction as well as manual processing. Reports in recent years have highlighted instances of child labor, illegal operations and unsafe health and safety conditions in mica production and processing.  

What We Do

The RMI works to provide tools, resources and partnerships necessary for downstream companies to carry out their due diligence in accordance with the OECD Due Diligence Guidance. To this end, the RMI:

  • Coordinates supply chain research by member companies to increase the understanding of the applications of mica in electronics and automotive products.
  • Has added mica to the Risk Readiness Assessment, enabling members to invite mica suppliers to the platform to complete the self-assessment against the industry norms covering social, environmental and governance issue areas.
  • Developed and maintains the Extended Minerals Reporting Template.
  • Issued the Global Workplace Responsible Sourcing, Environmental, Health & Safety Due Diligence Standard for Mica Processors.
  • The RMI’s Responsible Minerals Assurance Process (RMAP) provides independent third-party assessments for mica processors.
  • Works collaboratively with stakeholders such as the Responsible Mica Initiative to further transparency and responsible mica production and sourcing practices.
  • Has signed a Memorandum Of Understanding (MOU) with the Responsible Mica Initiative to develop a joint program to audit mica processors
