“Conflict minerals,” as defined by the US legislation, currently include the metals tantalum, tin, tungsten and gold, which are the derivatives of the minerals cassiterite, columbite-tantalite and wolframite, respectively. Downstream companies often refer to the derivatives of these minerals as 3TG.
- Note: Conflict minerals can be extracted at many different locations around the world including the Democratic Republic of Congo (DRC). The SEC rules define conflict minerals as 3TG metals, wherever extracted. For example, tin extracted in Canada, Russia or Argentina is considered a conflict mineral by definition. In the SEC rule, “DRC conflict-free” is defined as minerals that were extracted and did not directly or indirectly benefit armed groups in the covered countries. Therefore, tin extracted from Canada is considered “DRC conflict-free” under the definitions of the SEC rule.
The internationally recognized OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, has a broader scope and covers all minerals, not only 3TG.
