Conflict Minerals (CMRT) Declaration Tracker

Conflict minerals are minerals whose extraction or trade finances armed conflict, particularly in the Democratic Republic of Congo and adjoining countries. The '3TG' are the four covered by major regulations: tin, tungsten, tantalum and gold — ubiquitous in electronics, alloys and many manufactured products. Regulations (Dodd-Frank Section 1502 in the US, the EU Conflict Minerals Regulation) require companies to conduct due diligence on whether their products contain 3TG and trace their sourcing, to avoid funding conflict through their supply chains.

The Conflict Minerals Reporting Template — the standardized industry declaration (maintained by the Responsible Minerals Initiative) that suppliers complete to report whether their products contain 3TG and, crucially, which smelters and refiners are in their supply chain. It's the standard data-exchange format up the supply chain: you request CMRTs from your suppliers, aggregate them, and provide your own CMRT to your customers. Standardization is what makes due diligence scalable across complex multi-tier supply chains — everyone speaks the same template.

Because the smelter/refiner is the chokepoint where minerals can be traced to their source. Below the smelter, ore from many mines is mixed and origin becomes hard to verify; at and above the smelter, the smelter's sourcing practices determine whether the minerals are conflict-free. So the entire system traces 3TG back to the smelter and checks whether that smelter is conformant with a responsible-sourcing program (RMAP). A supplier's CMRT is ultimately a list of the smelters in their chain — and conformance is assessed at the smelter level, which is why the tracker captures smelter status, not just a yes/no declaration.

It becomes a due-diligence finding to address, not a dead end. Non-responsive suppliers need escalation — follow-up, management engagement, and (since the requirement is often legal and customer-cascaded) potentially sourcing consequences for persistent refusal. Suppliers with smelter gaps (non-conformant or unidentified smelters) need investigation: are those smelters actually in the relevant region, can the supplier improve their sourcing, or do you need an alternative? Regulations generally require you to conduct and document reasonable due diligence — not to achieve perfect certainty — so the documented effort to identify and address gaps is itself the compliance. The tracker's value is making that effort systematic and evidenced.
