Adhering to the principle of long-term cooperation and mutual growth with suppliers, we are building a green, sustainable, and digitalized supply chain system.

1. Supply Chain Sustainable Development Goals

In 2023, all primary raw material suppliers signed Social Responsibility Commitment and Integrity Commitment. Risk identification and on-site audits were initiated.

From 2024 to 2026, the company will complete risk identification and on-site audits of key raw material suppliers in stages, continuously building and optimizing the sustainable supply chain system.

2. Full life cycle ESG risk management

Supplier Access: Fully integrate ESG into supplier screening assessment

Risk Management Matrix: Implement hierarchical management of existing supplier and conduct ESG investigation and monitoring according to risk level.

Supplier Audit: Regularly conduct on-site supplier ESG audits, and suppliers are penalized and rewarded according to audit results.

Supplier Exit: Require rectification for ESG audit findings, and the suppliers who fail to meet the requirements by the deadline will face penalties such as cessation of cooperation.

Supplier Empowerment: Regularly conduct supplier ESG training and exchanges to empower the development of a sustainable supply chain system.

During supplier access screening and annual regular audits, we grade suppliers using Supplier EHS Audit Form and Supplier ESG Audit Form, evaluating their performance in areas such as labor management, environmental protection, occupational health and safety, and business ethics. ESG factors such as labor management are evaluated alongside quality, pricing, and other assessment criteria to determine supplier ratings and risk level assessment results.

If a supplier is involved in the following "zero-tolerance items " and poses significant potential risks, Tongwei reserves the right to terminate the new supplier introduction process or to cease cooperation with suppliers already in the pool.

Failure to obtain the necessary environmental permits

Illegal discharge of air emissions, wastewater, or solid wastes

Serious occupational health and safety problems

Failure to obtain the necessary occupational health evaluation, safety evaluation, filing and acceptance

Failure to obtain fire permits

Child labor, discrimination, forced labor, etc.

Failure to comply with the payment of employee salaries and benefits

Use of forged or false documents

Major breach of trust records

Commercial bribery

Unauthorized subcontracting

Use or procurement of mineral resources from conflict areas

3. Responsible Procurement

(1)Labor Safety and Health:

We are dedicated to collaborating with our suppliers to establish a workplace characterized by dignity, ethical standards, safety, and health protection. We conduct targeted assessments on critical issues such as child labor, forced labor, working hours, and labor safety and health. Through various channels, we assess the labor health and safety conditions maintained by our suppliers to ensure strict adherence to labor rights and the provision of a safe working environment that aligns with established standards.

(2)Green and Low-Carbon Supply Chain:

Adhering to the concept of green development, we actively implement green procurement and promote the green transformation of suppliers to create a low-carbon supply chain.

Green Procurement: We give full consideration to factors such as environmental protection, resource conservation, recycling and low-carbon, prioritizing the sourcing and utilization of energy-efficient, water-efficient, and material-efficient materials, products, and services under equal conditions. Furthermore, we proactively steer suppliers towards establishing a sustainable value chain within the industry.
Energy Saving and Consumption Reduction: We introduce advanced energy-saving technologies and equipment, promote packaging-free, green packaging and recyclable materials, and improve overall supply chain energy efficiency.

(3)Conflict Minerals:

We strictly adhere to the UN Global Compact, OECD’s Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, the Responsible Minerals Initiative (RMI), as well as other international conventions and industry initiatives. We procure mineral raw materials conscientiously, striving to ensure that all raw materials for our products are sourced in an appropriate manner. We actively promote suppliers to complete the CMRT Conflict Minerals Questionnaire while consistently carrying out the Company's responsible sourcing program.

(4)Procurement Traceability:

Establish an end-to-end, full-process supply chain traceability system from silicon, wafers, cells to modules.

Tongwei’s tracing methodology/capabilities have been verified by independent third-party entities such as STS, TÜV Rheinland, etc. According to the Supply Chain Verification conducted by TÜV Rheinland, the sectors of Module, Wafer, Ingot, and Polysilicon have attained AA ratings respectively, and sector of Cell has attained an A rating.
