Recently, Tongwei successfully passed the audit of TÜV Rheinland, an internationally authoritative third-party certification body, and obtained the "ISO 20400 Sustainable Procurement Conformity Statement" certificate. Meanwhile, with its outstanding value chain co-building practices, Tongwei was awarded the "520 Social Responsibility Day Sustainable Development Outstanding Case (Win-Win Value Chain)" award.

ISO 20400 is a globally recognized international guideline for sustainable procurement, guiding enterprises to integrate environmental, labor, compliance, and low-carbon requirements throughout the entire procurement lifecycle. It helps establish a full-process sustainable procurement management and control mechanism, improve supplier ESG due diligence, green procurement admission, and long-term empowerment systems, effectively manage supply chain risks, and enhance industrial chain resilience.

Over the years, Tongwei has been deeply committed to full lifecycle supply chain management, building a standardized sustainable procurement management system. It has established standardized processes in procurement compliance, supplier risk management, green procurement, and supplier empowerment, fully integrating environmental, social, and governance (ESG) factors into procurement strategies, policies, and daily operational workflows, aligning with global sustainable procurement standards.

The successful passage of the TÜV Rheinland ISO 20400 conformity assessment marks an important milestone in Tongwei's systematic advancement of responsible procurement and full-chain ESG management. Going forward, the supply chain will continue to adhere to international high standards across the entire procurement process, leverage the advantages of a chain leader to drive upstream and downstream partners in jointly improving sustainable governance, balance environmental, social, and economic benefits, and drive high-quality, long-term business development with the concept of sustainable development.

In the 2026 CSR China "520 Social Responsibility Day" Sustainable Development Outstanding Case selection, Tongwei was awarded the outstanding case honor in the "Win-Win Value Chain" category based on its comprehensive practices in supply chain ESG management system, continuous supplier empowerment mechanism, green and low-carbon supplier cooperation, and industrial chain collaborative value. The award was determined through comprehensive evaluation by a panel of experts from academia, public welfare, and ESG fields, combined with public voting.

CSR China is one of China's top ESG and corporate social responsibility professional think tanks, with over a decade of deep engagement in the sustainable development field. Each year, the "520 Social Responsibility Day" case solicitation targets leading enterprises across various industries nationwide, selecting real, implemented practices with replicable and scalable value. It focuses on supply chain responsibility, "dual carbon" action, rural revitalization, employee rights, and inclusive public welfare. The evaluation criteria balance system completeness, implementation effectiveness, industrial chain driving effect, and long-term social value, making it a highly credible industry honor in China's corporate social responsibility field.

This award represents the industry's high recognition of Tongwei's achievements in supply chain collaborative development, green and low-carbon transformation, and social responsibility implementation. It demonstrates the company's long-standing commitment to responsible procurement and building a green industrial chain, further consolidating its ESG brand image and providing a practical model for sustainable supply chain management in the industry.

Looking ahead, Tongwei's Global Supply Chain Center will take these two honors as a new starting point, leverage the advantages of a chain leader to drive upstream and downstream partners in jointly improving sustainable governance, balance environmental, social, and economic benefits, build a modern sustainable supply chain that operates efficiently, manages controllable risks, and pursues green and low-carbon development, and facilitate the green and low-carbon transformation of the whole society through industrial chain collaboration, achieving high-quality and sustainable collaborative development.
