Supply Chain Management
Basic Approach
Zeon Group believes that in order to fulfill social responsibilities such as environmental and human rights considerations across the entire supply chain, it is essential not only for our Group but also for our business partners to align our direction and advance initiatives together. As guidelines for our initiatives, we have established the Zeon Group Sustainable Procurement Guidelines, and we share the guidelines with our business partners and ask for their understanding of the objectives.
Going forward, we will continue to review the guidelines as appropriate in light of social demands for a sustainable supply chain, and, through collaboration with our business partners, fulfill our social responsibilities including environmental and human rights considerations.
Structure and System
We aim for a robust and sustainable supply chain by considering each of the environmental, social, and governance (ESG) aspects. As a system to advance this effort, we have established the Sustainability Conference and the Sustainability Committee under it, each of which meets regularly twice a year. These bodies also deliberate and decide as necessary on initiatives related to respect for human rights and the environment while also factoring in the supply chain, steadily advancing our measures. We have also established a supply chain reporting hub as a point of contact for any legal or compliance violations or human rights abuses within the supply chain.
Key Initiatives
Sustainable procurement initiatives
To promote sustainable procurement, Zeon works with its business partners to implement measures that embody concern for CSR (including human rights and environmental protection) throughout the supply chain. We take the steps outlined in the diagram below.

1. Sharing of our Sustainable Procurement Guidelines
In FY2023, we established our Sustainable Procurement Guidelines, which set out our Group’s fundamental approach to procurement and our commitment to building a sustainable supply chain. The Guidelines were distributed to suppliers in FY2024, and we are aiming to ensure that Zeon’s approach to sustainability and our strategy for related initiatives are disseminated throughout the supply chain.
In addition, to promote understanding and internalization of the Guidelines within the Company, we continue to conduct training sessions and briefings for procurement personnel to enhance their understanding and share key points for practical implementation.
Zeon Group conducts responsible procurement activities based on our " Sustainability Policy" aiming to realize a sustainable society throughout the supply chain.

We comply with laws and social norms and conduct fair procurement activities based on corporate ethics.

Sustainable Procurement Guidelines
2. Supplier surveys
To monitor the implementation status of suppliers’ sustainability initiatives and identify risks, we implement surveys targeting existing suppliers on a regular basis.
For the survey, we use the “Zeon Corporation CSR Procurement Self-Assessment Questionnaire” (SAQ), which was developed by the Company based on the common self-assessment questionnaire (SAQ) provided by the Global Compact Network Japan (GCNJ).
The purchasing departments for raw materials, materials, and logistics select those suppliers that account for over 80% of procurement value and suppliers that are felt to have a high risk of human rights related issues, etc.
In FY2024, SAQs were delivered by the relevant departments to a total of 140 suppliers, of which 134 suppliers (96%) returned a completed SAQ. With regard to the six non-responding suppliers, we checked the sustainability-related information on each company’s website, and confirmed that no major risks were apparent at the present time.

Establishment of a CSR promotion system, Establishment of internal controls, Establishment of a business continuity planning (BCP) system, Establishment of a whistle-blower system, and Dispatch of CSR-related information inside and outside the company

3. Identifying and analyzing risks based on survey results
Based on the above survey results, we analyzed the risks with each supplier and clearly identified points requiring improvements.
4. Feedback
We provide a feedback sheet based on the analysis resultsreferred to in 3. above to all suppliers that completed the common SAQ. The feedback sheet includes the score for each assessment item, including human rights, labor affairs, environmental protection, as well as the overall average score, a comparison with the previous survey, and an overall evaluation.
Suppliers can objectively understand their own progress, enabling them to continuously improve their CSR activities.
In addition, we conduct on-site assessments and hold feedback interviews for those suppliers that have a relatively low score on the common SAQ and may present higher CSR risks, and those suppliers handling raw materials that are deemed to be particularly high-risk from a CSR perspective. In the interviews, besides explaining the importance of sustainable procurement, we also confirm the status of initiatives based on the common SAQ, and request improvements where necessary. The average score for the five companies subject to on-site assessments and feedback interviews in FY2022 was 283 points (out of 900 points), but in FY2024, it had risen substantially to 488 points.

In FY2024, we also conducted feedback interviews with 11 companies. Through the dialogues outlined in the table below, we are advancing initiatives toward continuous improvement.
| CSR-related issues | Dialogue for improving CSR activities, and content of advice to suppliers |
|---|---|
| Enhancement of transparency |
|
| Formulation of a human rights policy | Introduction of the UN Global Compact and the formulation guidelines issued by the Ministry of Economy, Trade and Industry |
| Conflict minerals | Review of risk management status and sharing of issues related to conflict minerals |
Monitoring of suppliers
While conducting the due diligence described above, we will monitor overall changes in the common SAQ percentage score and the improvement status of companies with low percentage scores, and, as necessary, conduct on-site assessments and engage in dialogue for improvement through additional interviews. Through support that leads to improvements by our suppliers and other efforts, we will advance sustainability risk mitigation initiatives and work to strengthen our sustainable supply chain.
| 指標 | FY2022 | FY2024 |
|---|---|---|
| SAQ Collection Rate | 77% | 96% |
| Number of Suppliers Supported Through On-Site Audits and Feedback Meetings | 16 (6.1%) |
11 (7.8%) |
Collaboration with outside parties
We participate in the GCNJ’s supply chain subcommittee every year and gain diverse insights through it. We also actively engage in the preparation and publication of the subcommittee’s deliverables, incorporating them into our initiatives.
