This statement is based upon information collected from STW’s supply chain and manufacturing process.

Section 1502 (“Conflict Minerals Provision”) of the “Dodd-Frank Wall Street Reform and Consumer Protections Act” amends the “Securities Exchange Act of 1934” and is applicable for US-companies having reporting obligations toward the US Securities and Exchange Commission (SEC).

To support our customers STW is working toward the elimination of conflict minerals that directly or indirectly finance or benefit armed groups in the Democratic Republic of Congo (DRC) or adjoining countries from its supply chain.

STW’s ultimate goal is to have a supply chain that consists of material that is DRC Conflict Free.

As we do not source directly from smelters or mines, we are working closely with our own suppliers to understand the sources of the metals contained in their products, to assure to reach the goal above.

Therefore we will exercise due diligence as specified in the document “Due Diligence Guidance for Responsible Supply chains of Minerals from Conflict-Affected and High Risk Areas (2nd Edition)” from the Organisation for Economic Co-operation and Development (OECD).
