Internal Reviews and External Audits

Based on the above policy, we conduct the following four-stage review process for new suppliers. We also conduct annual follow-up audits of existing suppliers to improve Products quality.

Step 1: Risk Assessment

We assess risks such as whether the new supplier is a sound company, has a stable business foundation, and has any financial issues. In addition to requiring the submission of documents such as business licenses, we may request an investigation by an external research agency if necessary.

Step 2: Self-Audit Through Document Review

Before the on-site audit, we first request a document review to confirm that the basic requirements are met. In addition to quality-related matters, the document review also covers ISO certification and compliance with environmental standards.

Step 3: On-Site Audit Through a Factory Visit

After passing the document review, an on-site factory audit is conducted. The Quality Audit Department, CE (Component Approval Department), and Purchasing Department visit the factory together and conduct a general process audit as well as a document audit for ISO and other standards.

Step 4: Final Assessment

Based on the audit results, companies requiring improvements must submit an improvement report. Companies that score 90 points or higher, our passing standard, are approved as official business partners.

Annual Follow-up Audits:We also conduct annual follow-up audits of existing suppliers to continuously ensure that quality standards are maintained and improved.
