Key takeaways:
- The regulation applies to EU-based importers of tin, tantalum, tungsten and gold, whether these are in the form of mineral ores, concentrates or processed metals, with indirect impact on global smelters and refiners
- The CMR does not apply to recycled products, but it does apply to products that are by-products.
- Aligned with OECD Due Diligence Guidance
- Around 600-1,000 EU importers and ~500 global smelters/refiners affected
- EU provides an indicative list of conflict-affected and high-risk areas (CAHRAs) to guide risk assessments. You can access it here.
- To help companies, the European Commission will create a so-called "white list" of global smelters and refiners which source responsibly.
