Stakeholder Communication
HANTECH's Diverse Communication Channels with Shareholders, Customers, Employees, Suppliers, and Communities
Stakeholder Engagement
HANTECH BIO-TECH recognizes that corporate management involves not only operating performance and profitability, but also environmental, social, and governance (ESG) impacts. We are committed to maintaining honest and transparent communication with stakeholders to ensure that corporate decisions address diverse needs and create value through both business performance and sustainability.
To strengthen the identification and management of material sustainability issues, HANTECH BIO-TECH refers to the GRI Sustainability Reporting Standards (GRI Standards) and follows the AA1000 Stakeholder Engagement Standard as its communication framework. Based on the five principles of responsibility, influence, tension, diverse perspectives, and dependency, the company identified seven major stakeholder groups: shareholders, customers, suppliers, government agencies, employees, communities, and financial and insurance institutions. This helps ensure effective communication mechanisms and appropriate responses to stakeholder concerns.
HANTECH has dedicated communication channels for each stakeholder group and maintains ongoing communication and discussion on important issues.
Material Topic Identification and Analysis
Material Topic Assessment Process
Following international sustainability standards and the latest development trends, HANTECH refers to the GRI Sustainability Reporting Standards (GRI Standards), the Sustainability Accounting Standards Board (SASB) Standards, the Sustainable Development Goals (SDGs), and the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). The company also analyzes sustainability issues addressed by industry benchmark companies and combines these insights with its business development strategies and stakeholder concerns to assess the impact of each sustainability issue. Through systematic management and multi-party assessment, HANTECH ensures that sustainability goals are linked to concrete actions, strengthening corporate resilience and sustainable competitiveness.
Material Topic Management
Based on international sustainability standards and trends, together with the characteristics of the company’s industry, HANTECH identified 15 actual and potential sustainability issues across the three ESG dimensions.
A Chinese-language questionnaire survey was conducted among company executives and seven major categories of external stakeholders. A total of 233 valid questionnaires were collected, representing a response rate of 83.51%.
Following stakeholder communication and weighted assessment, the level of stakeholder concern and each issue’s impact on the company were evaluated and reviewed by senior management. Eight key sustainability issues for 2024 were ultimately identified as priorities for future development.

2024 Material Topic Impact Overview
Based on the material topic analysis results, the company discloses the management approaches and related information for eight material topics in its Sustainability Report for stakeholder reference. The 2024 identification results are also incorporated into ESG policies and long-term goals to ensure the implementation of sustainability strategies and support the company’s steady growth.
