Responsible supply chain
We comprehensively and systematically manage all levels of suppliers, actively urge suppliers to improve their ESG performance, work together to build a green and responsible supply chain, and promote the coordinated development of economic, social and environmental benefits.
By implementing the "Supply Chain Procurement Cost Control" project, we closely monitor market price fluctuations and use advanced analytical tools and methods to improve the foresight and accuracy of price forecasts.
Establish a "supply chain procurement volume assurance" project, conduct in-depth assessments of the impact of international anti-circumvention investigations , and respond to the complexity and uncertainty of the international trade environment .
By improving our overseas localized supply capabilities, we not only meet the changing market compliance requirements , but also further consolidate Trina Solar's global market layout and enhance the company's international competitiveness.
Supply Chain ESG Requirements

Supplier empowerment and training

Trina Solar's 10th Supplier Empowerment Training Camp
In October 2023, in order to further improve the management of product quality, process quality and flow quality, Trina Solar launched the 10th Supplier Empowerment Training Camp for more than 100 suppliers with the theme of "Illuminating the Future with Quality and Building a New Ecosystem for the Photovoltaic Industry Together". We empower suppliers from three aspects: lean management, quality and customer success. The main contents include: rapid on-site improvement (lean foundation + seven wastes), value stream, quality control circle (QCC), error prevention , rapid problem-solving methods, 8D, measurement system analysis (MSA) basics, process capability analysis, etc., to help Trina 's quality management reach a new level.
Supplier Access Ratings
In 2023 , we further require suppliers to communicate the environmental and human rights requirements set out in the Supplier Code of Conduct and the ESG-related clauses listed in the contract to their supply chains.

Supplier Performance Evaluation
Trina Solar has established and implemented the "Supplier EHS and Social Responsibility Management Procedure", which clearly stipulates that procurement personnel should record the supplier's relevant performance in the "Supplier EHS and Social Responsibility Questionnaire".The questionnaire includes an assessment of 56 indicators in five areas: environmental protection, occupational health and safety, fire safety and emergency preparedness and response, labor and human rights, and business ethics and sustainable procurement.
For suppliers/contractors that fail to agree with Trina Solar's EHS and social responsibility requirements, or fail to continuously improve their environmental health and safety levels, or do not focus on fulfilling their social responsibilities, we will propose measures such as requiring them to make rectifications within a specified period of time or terminating the cooperative relationship .

Conflict Minerals Management
Trina Solar's conflict minerals goal is to 100% not purchase or support the use of "conflict minerals".
We published and implemented the Conflict Minerals Management Framework in 2015, which defines a five-step process to identify conflict minerals that may be contained in the materials we use . We continue to encourage key material suppliers to complete CMRT due diligence and continue to disclose conflict minerals management performance in our annual sustainability report.

We have established a one-point-five-face supply chain digital system architecture with ERP system as the foundation, order management (ERP-SO), planning management (SCP system), procurement management (SRM system), manufacturing management (MES system), and logistics management (TMS system) as the backbones, to achieve online management of the main business processes within the supply chain from internal generation of customer orders to order manufacturing and delivery, and realize visual management of the entire life cycle of orders through data integration.
Supply Chain Finance
In 2023, Trina Solar successfully built the first supply chain finance platform "Trina Rongtong" in China's photovoltaic industry , providing a unified financing portal for core enterprises, suppliers and financial institutions, connecting with various bank products, realizing online management of financing operations, real-time grasp of financing quotas, and clear financing progress.
On the first day of its launch, “Tianhe Rongtong” helped suppliers obtain online financing of more than 30 million RMB.
By the end of 2023, the number of companies connected to the platform has exceeded 300, including manufacturers of EVA photovoltaic films, aluminum frames, plastic particles, etc.
