Conflict Minerals

Our commitment

Our products and services are at the heart of our sustainability strategy, enabling our customers to create a cleaner, healthier world.  We want to ensure we make our products in ways that are ethical and respect human rights throughout our operations and value chain. 

In Conflict-Affected and High-Risk Areas (CAHRAs), the mining of tin, tantalum, tungsten and gold (3TGs) can be used to finance conflict between armed groups, fuel forced labour and other human rights abuses, and support unethical business practices. While Johnson Matthey has no mining operations in CAHRAs, we do produce certain products that contain 3TGs (eg, catalysts for the automotive sector).  

Our Conflict Minerals Policy (Policy) sets out our commitment to source 3TGs in a manner that does not directly or indirectly contribute to such abuses and harms in CAHRAs.  

Johnson Matthey publishes its CMRT on a calendar year basis in accordance with the US Dodd-Frank Wall Street Consumer Protection Act, Section 1502 and Regulation (EU) 2017/821 of the European Parliament and of the Council (EU Regulation).

We would be happy to send you our CMRT for the past calendar year upon request (email to:
