Conflict Minerals Policy

MDI supports the goal of the Dodd-Frank Act of preventing armed groups in the Democratic Republic of the Congo and adjoining countries from benefitting from the sourcing of Conflict Minerals from that region.

MDI is committed to ensuring that we are not sourcing 3TG minerals that fund armed groups in the DRC and adjoining countries. We do not explicitly ban the sourcing of minerals from this region as this may harm legitimate miners.

We take steps to ensure that our vendors do not fund armed groups in the DRC and adjoining countries through their sourcing of minerals. We carry out reasonable country of origin inquiries on the relevant products we manufacture when necessary and perform supply chain due diligence when necessary following the processes and procedures set forth in the OECD’s Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. We also have in place corrective action measures in the context of conflict mineral sourcing. Our Quality Assurance Manager is responsible for these efforts.

We expect suppliers to have a policy in place and implement a system to trace the origin of 3TG minerals supplied to MDI following the template developed by the Responsible Minerals Initiative. Suppliers should develop Conflict Minerals policies, due diligence frameworks, and management systems that are designed to prevent Conflict Minerals that are not DRC Conflict Free from being included in anything sold to MDI. We expect that no supplier of MDI provides us with any minerals that are not conflict-free.  

If any of our suppliers has challenges in complying with these expectations, we are willing to work to address them. If compliance cannot be achieved, we will terminate the relationship with the supplier.
