What minerals are considered “conflict minerals”?

“Conflict Minerals” currently include gold, tin, tantalum and tungsten, the derivatives of cassiterite, columbite-tantalite and wolframite, respectively. These conflict minerals are referred to as “3TG”.

What is section 1502 of the Dodd-Frank Act?

Effective July 21, 2010, Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act requires companies regulated by Securities and Exchange Commission (SEC) to inquire into the origin of the conflict minerals in their supply chain and report on the due diligence or reasonable inquiries to determine whether conflict minerals contained in their products are sourced from the DRC (Democratic Republic of Congo) or adjoining country or if they are from recycled or scrap sources.

Does the Dodd-Frank Act make it illegal to use conflict minerals if they originate in the DRC or from the other covered countries?

No. The Dodd-Frank Act rule relates to disclosure only, and they do not prohibit the use of conflict minerals in products at this moment.

Are there any standards being developed for electronically passing this data between tools (like the IPC1752A for hazardous substance information)?

The EICC/GeSI template is the essential form. It provides the ability to make one declaration for an entire company, division, product, or part.

SEC files only apply for false disclosures. Customers will have various responses, the most serious of which will be the loss of business and removal from the customers' approved vendor/supplier list.
