Some minerals, tantalum (Ta), tin (Sn), gold (Au), tungsten (W) ,cobalt(Co) originating from the Democratic Republic of the Congo (“DRC region”) or adjoining countries, are commonly referred to as "conflict minerals".
Under the guideline of OECD (Organization for Economic Co-operation and Development), the laws-of-the-United-States and international organizations regarding conflict minerals, a rational investigation into place-of-origin or due diligence is requested for confirming whether any conflict mineral is contained in the end product throughout the entire supply chain.
Daisho Denshi recognizes that the procurement of certain minerals (notably tin, tantalum, tungsten, gold and cobalt) from states in conflict areas and other high-risk areas carries with it a risk of funding organizations that are involved in all kinds of illegal or unethical activities including human rights abuses such as child labor, harsh working conditions, environmental destruction and corruption. This is a matter of grave social concern.
In order to fulfill our corporate social responsibility, Daisho Denshi promotes responsible procurement of minerals in the global supply chain.

In the U.S., a law was passed and put into effect in January 2013 requiring major corporations to report their status and use of any conflict minerals.
