JA Solar's Integrated Traceability System
What is traceability and why does it matter?

Traceability is the ability to monitor material flows across the supply and production chain. It is meant to ensure and to clarify on where materials come from, how they move through production, and how they are transformed along the way. Customers, stakeholders, responsible sourcing requirements and local laws may require transparency as to the origin of materials and items throughout the supply chain. These requirements can only be met by a comprehensive traceability system with consistent record-keeping, inventory audits, reporting, data entry, and data flow across systems.

JA Solar's Integrated Traceability System (ITS)
As a company that is vertically integrated up the ingot level of the polysilicon supply chain, JA Solar is very well positioned to trace. JA Solar has invested heavily and created our integrated traceability system (ITS). ITS is a comprehensive traceability system that -- by way of defined protocols and processes -- allows JA Solar to track material movement across the polysilicon supply chain to the final module production.
JA Solar also works with independent third-party experts to assess the traceability capabilities of key suppliers. This approach includes upstream supply chain mapping and the independent validation of sourcing claims made by suppliers regarding their raw material inputs. This approach ensures up-to-date information about the origin and data accuracy more generally.
Framework of Supply Chain Due Diligence
Due diligence

Due diligence is a dynamic and risk-based process that enables companies to proactively address ESG concerns, such as environmental and human rights impacts, and to conduct their business in a responsible and sustainable manner. Our supply chain due diligence framework is aligned with leading international standards, including the OECD Guidelines for Multinational Enterprises and the United Nations Guiding Principles on Business and Human Rights. Our approach is also grounded in internationally recognized labour standards, such as those defined by the International Labour Organization.

Our policies
Our key guiding policies and statements are the following
1.JA Solar Code of Conduct, JA Solar Supplier Code of Conduct,
2.JA Solar Human Rights Policy,
3.JA Solar Responsible Sourcing Policy, And
4.JA Solar Responsible Sourcing of Minerals Statement.

All of the aforementioned policies are publicly accessible through the JA Solar download center. These documents define and uphold JA Solar's firm commitment to human rights and responsible sourcing practices promoting transparency, compliance, and accountability across all levels of our operations.

How these policies are implemented in practice
JA Solar follows a risk-based due diligence process across its supply chain to ensure compliance with ESG standards and to mitigate risks. Our approach covers pre-screening, onboarding, and continuous monitoring, such as:
A screening process for selecting new suppliers, taking into account ESG requirements.
Contractual assurances from our suppliers to comply with our ESG requirements and JA Solar's Supplier Code of Conduct.
Monitoring through regular reviews, ESG questionnaires and audits of JA Solar suppliers, to confirm their compliance with our ESG requirements, as well as to collect and assess relevant information concerning possible adverse impacts in accordance with requireme- nts of relevant ESG and due diligence legislation.
In case any issues or instances of non-compliance are discovered, the supplier is requested to take corrective actions, and JA Solar will track the suppliers' progress in doing so and will follow-up with a review focused on assessing whether the corrective actions have been effective. In case of major or continued non-compliance, the supplier relationship will be terminated.
Grievance Mechanism: JA Solar SpeakUp Line

To further enhance accountability, JA Solar has implemented a grievance procedure through which stakeholders, including workers, suppliers, affected persons, civil organizations, and any other interested parties, can report concerns about our operations or those of our suppliers. Our ‘SpeakUp’ channels can be found at our website at jasolar.speakup.report/en-GB/wb/home. Everybody who believes to be negatively affected by JA Solar or its suppliers can make a submission resulting in an investigation which will be conducted in line with JA Solar's SpeakUp Policy and Procedure.
