Dealing with conflict minerals

Some minerals originated in Democratic Republic of the Congo (DRC) and adjoining countries are the financial sources of armed groups and anti-government organizations. They enhance the conflicts and are related to serious human rights abuses, child labor, forced labor and environmental destruction. Those minerals produced in these areas (tin, tantalum, tungsten, gold, and cobalt), that are supporting above mentioned groups are called Conflict Minerals.

On 21 July 2010, in order to cut off the financial sources of above mentioned groups, the United States Congress enacted Section 1502 of the Dodd–Frank Act that requires companies listed on SEC to provide disclosures about the use of specified conflict minerals in their products.

Considering the purpose of the law, Toppan Photomask has determined not to use conflict minerals related to these groups, and addressing in accordance with the OECD Due Diligence Guidance.

We maintain transparency in the supply chain aligned with business partners, undertaking its best efforts towards "DRC Conflict-Free".
