CSR procurement

The Topre Group has established the “Topre Group Supplier CSR Guidelines” for the further promotion of CSR procurement, and under the Basic Philosophy of “contributing to society through the creation of products and services using its outstanding technologies,” clarifies its approach to CSR as well as requirements for business partners concerning human rights, labor, health and safety, anti-corruption measures and consideration for the environment, and promotes CSR initiatives across the supply chain together with business partners.

Initiatives for the promotion of CSR procurement

Through the “Topre Group Supplier CSR Guidelines” issued by Topre, we will have existing business partners understand CSR activities centered on quality, human rights, the environment and compliance with laws and regulations, and request the diffusion and spread of CSR initiatives.
In addition, we will work on the promotion of sustainable procurement in cooperation with business partners by asking them to fill out a “Confirmation of Agreement,” including matters such as cooperation with each guideline.


Survey of CSR activities of business partners

Topre Group conducts a supplier CSR survey once a year in each domestic business division of suppliers selected based on the importance of parts and transaction volume.
Surveys are conducted on topics such as "general CSR, safety and quality of products and services, human rights and labor, the environment, and compliance," and the results are converted into a score and evaluation to identify suppliers with high potential risks in terms of CSR activities.
We are working to improve CSR among our suppliers, including by requesting voluntary improvements from suppliers identified as high risk.

Promotion of green procurement

The group has established the “Topre Group Green Procurement Guidelines” as its basic way of thinking on consideration for the environment in procurement activities, including the company’s way of thinking on carbon neutrality and a request to business partners to reduce CO₂ emissions.
In addition, as an initiative at the procurement stage, we promote “green procurement,” by which we procure from business partners who are positive about environmental improvement activities, such as materials, parts and units considerate of the environment.


Strengthening of supplier partnerships

Our business partners are important for us to produce high-quality products, and we believe the building of cooperative systems is important.
The group holds a supplier conference once a year to explain the group's current situation, strategies, purchasing policy and Topre initiatives.
About 150 suppliers participated in the event, which was held on the web on July 10, 12, and 14 in fiscal year 2023. We will resume holding the conference in-person from fiscal year 2024.
In these guidelines, we ask that business partners act in accordance with the "Topre Group Supplier CSR Guidelines" and "Topre Group Green Procurement Guidelines", and also ask for their cooperation in a Supplier CSR Survey to confirm the CSR efforts of each business partner, as well as in reducing CO2 emissions.
We will promote procurement that emphasizes CSR and the environment, strive to build relationships of trust with business partners throughout the group, and aim to contribute to the realization of a sustainable society.

At the company's QC Circle Competitions, we share information on quality and manufacturing processes and consider issues. We also ask business partners to present examples of their quality improvements and work with them to raise awareness of quality.
Apart from that, the company's Parts Acceptance Division visits suppliers regularly to conduct on-site audits of manufacturing processes, provide advice on improvements, and propose improvements to the work environment.

Sustainability Initiatives for Business Partners

We ask our suppliers to understand our sustainability through the "Topre Group CSR Guidelines" and "Topre Group Green Procurement Guidelines".
In fiscal year 2023, we visited several business partners to explain Topre's efforts to reduce greenhouse gas emissions.
In addition, in fiscal year 2024, we will expand the number of target suppliers to 37 companies and hold briefing sessions on reducing greenhouse gas emissions, including education for suppliers that do not have a Carbon Neutral system in place.

Tour of Topre Kyushu Kanda Plant by Topre Cooperative Association

In response to the results of a questionnaire survey of suppliers at the supplier convention held in May 2024,
we invited the Topre Cooperative Association (43 companies participated this time) to gather at Topre Kyushu's Kanda Plant for a plant tour and information sharing,
The event provided an opportunity for the suppliers to tour the plant and share information.
We will continue to promote procurement that places even greater emphasis on CSR and the environment together with our suppliers.

Business partner hotline

In order to maintain fair, impartial, and highly transparent transactions with related business partners, the group has established a contact point for business partners to report.
We promise to protect reporters so that there is no disadvantageous treatment or deterioration of the trading environment due to reporting, and handle personal information based on the company’s protection of personal information.
This contact point has been established in a division independent of Purchasing Division, and the manager in charge of compliance investigates the details reported and takes appropriate action.


Purchasing personne

The group provides education to employees towards the thorough implementation of fair and transparent transactions and the promotion of CSR throughout the supply chain, and provides regular education and training for purchasing personnel.
In recent years, these efforts have led to an increase in the skills and knowledge of personnel in charge of subcontracting, compliance, CSR procurement and other areas of particular importance.
In addition, we also provide education and guidance on their attitude as employees and buyers.
