Organizational Importance and Commitment

Opportunities and Impact

Effective supply chain management is a key factor influencing operations, helping to increase profit efficiency and enhance competitiveness, while also creating business opportunities and supporting organizational sustainability. However, poor supply chain management can cause environmental, social, and economic impacts, leading to business disruptions, legal violations, fines, operational losses, and reputational damage. Therefore, careful supply chain planning and management are crucial factors for the organization’s long-term sustainability.

Management Guidelines

1. Risk Assessment from Supplier Operations

The Company places importance on effective supply chain management by implementing policies for quality procurement processes, both for central procurement and project-specific procurement. This is achieved through supplier evaluations to ensure that partners have the capability to deliver quality products and services that meet the specified criteria, quantities, timelines, and delivery procedures as defined by the Company. In addition, partners must comply with labor laws, environmental laws, and relevant quality management system standards.

The Company analyzes and classifies its trade partners into 5 priority groups as follows:
Tier 1 Suppliers
Suppliers who provide products or services directly to the Company.
Non-Tier 1 Suppliers
Suppliers who provide products or services to the Company’s direct suppliers or to the next tier in the supply chain.
Critical Tier 1 suppliers
Suppliers with high order volumes, continuous orders, and whose products and services are important to the Company’s business operations or are difficult to substitute with other suppliers.
Critical Non-Tier 1 suppliers
Manufacturers or service providers critical to the Company’s business operations and difficult to replace by other manufacturers or service providers, who sell to agents that are the Company’s direct suppliers or to the next tier in the supply chain.
Sustainability High-Risk Suppliers
Suppliers with a sustainability assessment score of Level 3 or higher, whose operations may potentially cause negative impacts on the Company’s operations and reputation.
