Responsible Units (Governance)

Board Oversight: The Board of Directors holds ultimate supervisory responsibility for supply chain management, working through the RBA Implementation Committee under the Sustainability Development Committee to regularly review supply chain strategies and risk controls.
CDP External Ratings: Starting in 2025, CDP questionnaire disclosures were introduced (Climate Change: B / Water Security: B-), with external feedback integrated into annual reviews to continuously enhance supply chain governance.

Policy Commitments (Strategy)

Compliance & Tiered Management: Adhere to RBA guidelines and international regulations by executing tiered management and periodic evaluations per internal procedures, tracking non-compliant suppliers for corrective action to accelerate supply chain sustainability.
Green & Responsible Procurement: Proactively eliminate high-risk substances during R&D to maintain product compliance with IECQ QC 080000, RoHS, and REACH; embed ESG criteria into supplier selection while encouraging vendors to conduct energy audits and GHG inventories.

Negative Impact (Risk)

International geopolitical and macroeconomic volatility can trigger raw material price fluctuations and supply chain disruptions.
Failure by suppliers to concurrently elevate ESG management performance may spill over to damage corporate brand equity, corporate image, and customer trust.

Positive Impact (Opportunity)

Tiered supplier management enables early identification and mitigation of material shortage risks.
Driving supplier carbon reduction not only facilitates progress toward Scope 3 emission targets, but also sharpens product competitiveness and strengthens advantages in securing international orders.
