Policy on Responsible Procurement of Minerals

For some mineral resources traded in the world, it is sometimes pointed out that processing sites, such as mining sites or smelters, are involved with armed forces, grave violations of human rights and environmental destruction.

Toho Titanium Group has a basic policy of not procuring or using minerals that bear OECD Annex II risks ((1) Violation of human rights related to mining, transportation and trading of minerals, (2) Direct or indirect support for non-state armed groups, (3) Illegal acts by public or private security forces, (4) Bribery and false statements of the origin of minerals, (5) Money laundering, and (6) Nonpayment of taxes, commission fees and mining right fees to the government) in conflict-affected and high-risk areas (CAHRAs) in regard to tin, tantalum, tungsten, gold, cobalt and mica, and checks for the presence of the aforementioned risks when procuring said minerals.

In the event of discovering risks in the supply chain, we will take corrective measures.

In order to adhere to this policy, we request our business partners to understand our corporate group’s philosophy and engage in responsible procurement of minerals.
In addition, we appropriately disclose information on this kind of initiatives to all stakeholders.

Toho Titanium Group CSR Procurement Policy

Our corporate group has established the “Toho Titanium Group CSR Procurement Policy” in order to fulfill our social responsibilities throughout the supply chain, including the compliance with laws and social norms and consideration for human rights and the environment. We request that our business partners around the world comply with the policy and ask for their understanding and cooperation.

CSR survey

Since FY 2022, our corporate group has used the “CSR Procurement Self-Assessment Questionnaire” published by the Supply Chain Subcommittee of Global Compact Network Japan (GCNJ) in order to conduct research activities targeting our major suppliers in each business that have a high impact on transaction volume and new suppliers.
The “CSR Procurement Self-Assessment Questionnaire” consists of 9 items: corporate governance, human rights, labor, environment, fair corporate activities, quality & safety, information security, supply chain, and coexistence with local communities. Based on the results of the surveys on suppliers, we confirm whether they meet the standards set by our corporate group and conduct interviews when necessary.
In addition to this survey, we conduct regular audits of our major suppliers every year, which helps us improve our CSR level.
Furthermore, our corporate group does not have a track record of procuring from high-risk suppliers judged to have or have the potential to pose problems in terms of environmental impact, human rights, or labor, and we will not procure from them in the future either.

Confirmation of environmental impact reduction based on the CSR survey

Based on the results of the “CSR Procurement Self-Assessment Questionnaire,” our corporate group is working to reduce the environmental impact of the entire supply chain by confirming the efforts of target suppliers to reduce emissions of CO2 and waste and consumption of electricity, water, and energy.

We will endeavor to develop a working environment where senior employees can keep working for a long period of time with no worry, while considering their health and physical capacity.

Development and utilization of personnel

Our corporate group has formulated a mid/long-term plan for developing personnel, for the purpose of establishing and fortifying the “HR base,” which is included in our basic policy for mid/long-term management strategies, and believes that human resources are the sources of business operation. In addition to the education for improving hands-on skills, which is aimed at acquiring or handing advanced techniques on to the next generation, and the education of individual themes, which is aimed at improving awareness and knowledge, we designate instructors for new employees fresh out of high school, college, and graduate school, who will lead our future business, produce individually customized plans for instructing and training them, and develop personnel as planned. In addition, we offer collective education so that employees can master necessary skills and knowledge according to their respective posts, operate a system for short-term overseas study for developing “global personnel” and “personnel in charge of reform” early, and hold training for selective education, etc. Furthermore, we have various programs for honing the skills of each employee through personal development.

Safe, comfortable working environment

Measures for occupational safety and health

Under the basic policy of giving top priority to safety, our corporate group engages in various activities for securing a comfortable working environment and achieving zero industrial accidents. (In detail, we aim to decrease the rate of accident per 1,000 employees in one year* with absence of 4 days or longer to 0.7 or less in FY 2022.)

At the Chigasaki Plant, the plant manager is designated as a general safety and health manager defined in the Industrial Safety and Health Act. At other plants, the management of safety and health in each production line is conducted under the instruction of plant managers. The Safety and Health Committee led by labor and management regularly holds a discussion for improving the safety and health of workers at business establishments. We conduct group-wide health activities by grasping the situations of dust, noise, and specific chemical substances in the working environment, improving the working environment when necessary, and so on.

*It is the number of workers who get injured or die per 1,000 workers per year, and can be expressed by the following equation:

Rate of accident per 1,000
employees in one year
Number of workers
who get injured or die in a year
× 1,000
Average number of
workers in a year

Basic policy for safety and health

We recognize that the safety and health of our workers are the foundation of our corporate activities. Thus, safety is our top priority, which is why we aim to achieve a comfortable and attractive workplace where all workers can work safely in good health while securing peace of mind in all the Toho Titanium Group business areas.
