Challenges and Opportunities
Challenges
The Company must manage its supply chain within an increasingly complex business environment, including raw material price volatility, supply continuity, product quality, regulatory compliance, and growing stakeholder expectations regarding environmental, social, governance (ESG), and human rights performance.
In addition, extending ESG practices across suppliers and contractors requires continuous communication, assessment, monitoring, and supplier capability development. These efforts are essential to ensuring consistent standards throughout the supply chain and effectively mitigating risks that could impact the business.
Opportunities
Responsible supply chain management strengthens raw material security, mitigates risks related to product quality, delivery performance, costs, and corporate reputation, and enhances confidence among customers, shareholders, investors, and other stakeholders.
At the same time, ESG supplier assessments, the development of a Supplier Code of Conduct, and the adoption of technology in raw material inventory management help improve operational efficiency, foster long-term collaboration with suppliers, and support sustainable growth across the value chain.
