ESG

Supplier Management Policy

In order to mitigate the impact of the product value chain on the local environment and society, RichWave Technology has established a quality assurance department to supervise and ensure that the supply chain complies with regulatory requirements and fulfills its social responsibilities in terms of environmental protection, occupational safety and health, and labor human rights. The supplier management process of RichWave Technology is as follows. We require new suppliers to introduce the ISO14001 and QC 080000 environmental management systems, and they must pass the quality and environmental management system (HSF) audit, including material hazardous substances test reports, material safety data sheets (MSDS), and HSF compliance declaration, to properly control hazards to the human body and the environment with respect to products and their production processes.
