Fulfill corporate social responsibility and focus on conflict minerals issues

PEWC require suppliers to follow:

• 01 Must fulfill corporate social responsibilities.
• 02 Ensure that products do not use "conflict minerals" from the DR Congo and the surrounding countries, but do not resist "conflict-free minerals" from their regions.
• 03 Promise to use only metals from independently smelters or refineries.
• 04 Communicate the requirements to upstream suppliers.
