The Regulation, as agreed by the EU Institutions, is set to ensure sustainable sourcing for more than 95% of all EU imports of tin, tantalum, tungsten and gold, which will be covered by due diligence provisions as of 1 January 2021. Companies effected will have to carry out a number of measures, these include the development of reporting tools and standards to further boost due diligence in the supply chain, as well as setting up a transparency database. Those downstream operators who import refined, metal-stage products into the EU will be covered by the mandatory obligations.
