Our Metals business consists of three areas of business; mining, smelting and refining, and resource circulation. In the mining sector, we invest in overseas copper mines in order to procure a steady supply of copper concentrate. In the smelting and refining sector, we manufacture and sell high quality products, both domestically and overseas, thanks to the Mitsubishi Process, which combines high efficiency with exceptionally low environmental impact. Making the most of the smelting process, we have also established a recycling system for efficiently recovering valuable metals from E-Scrap and other sources, as part of our active commitment to recycling resources. We also provide precious metal bullion products and services under the brand “Mitsubishi Gold,” including our accumulation plan service called “MY GOLD PARTNER” for gold, silver and platinum for individual customers. In the resource circulation sector, we process waste products such as home appliances and automobiles for recycling, while also coordinating with the smelting and refining sector in an effort to expand resource circulation.
Advanced Products Company (APC) operates two businesses in an integrated manner - the Copper & Copper Alloy business and the Electronic Materials & Components business - since they are very similar in terms of market needs and technology development. Taking advantage of our unique technologies, we offer various products in the markets of next-generation vehicles, semiconductor manufacturing, electronics, industrial equipment, robots, and infrastructure, which are our focus market domain.
We supply wide range of products for semiconductor manufacturing and electronics market as well as automotive industry; oxygen-free copper and advanced copper alloys, lead frames and various other copper products that are essential to handle high current, high voltage and high capacity data communication required to next generation vehicle; solar heat-ray shielding paints that are used mainly for automotive windows to save energy; electronic components such as thermistor sensors; processed silicon products and sealing products for semiconductor manufacturing equipment. In addition, we supply superconducting wires (used for magnetic resonance imaging (MRI) scanners and scientific research), high-performance alloy wires, ECO BRASS® and GloBrass® (an environmentally friendly, lead-free superior machinability brass), and others for the market of industrial equipment, robotics, and infrastructure.
In this way, APC contributes widely to the development of society, like a popularization of new mobility services, by providing high value-added products in response to mega trends.
We supply the cutting tools and cemented carbide products such as construction tools and wear resistant tools that are essential for processing metal parts. We operate manufacturing and sales facilities worldwide, in China, and other parts of Asia, the U.S. and Europe. By providing high value-added products and services that cater to customer needs, underpinned by high levels of technical expertise and reliability, we support manufacturing across various fields and boast the largest domestic market share for cemented carbide products. We are also focused on the collection of used cemented carbide tools. For example, we proactively recycle tungsten, a rare metal that is the main raw material for cemented carbide.
In the Renewable energy business, we contribute to the building of a decarbonized society by providing a stable supply of renewable energy, including geothermal, hydroelectric, solar, biogas and wind power.
We operate a wide range of affiliated businesses via our Group companies with diverse characteristics. For example, we have developed former mining sites for utilization as tourist roadways, while recycling companies have developed technologies to take incineration fly ash that has a high chlorine concentration remaining after the incineration of general waste and wash it until the chlorine concentration is low enough to turn it into cement resources. In this way, we have achieved the complete recycling of incineration fly ash, something that has traditionally been difficult to achieve.
In the cement business, we have established a wide-ranging business structure, from mining limestone, the main raw material in cement, through to cement plants, transportation, sales, ready-mixed concrete plants, and construction companies, etc. With this structure, we contribute to the development of social infrastructure and undertake global activities via production and sales facilities in Japan and other countries. We also supply high quality products such as low-heat cement, ultra-high strength concrete cement, and non-shrink grout, in addition to regular Portland cement and other general-purpose products. Furthermore, we actively take in difficult-to-treat waste products at our cement plants, and detoxify them using a high-temperature burning process at approx. 1,450ºC. Effectively reusing resources like this enables us to contribute to the establishment of a recycling-oriented society.

As a comprehensive materials manufacturer, we promote partnership and coexistence with wide range of suppliers throughout the value chain to improve added value. We also actively develop global procurement activities with the aim of stable product supplies and more competitive products.
As stable procurement leads to consistent operations and reduced opportunity loss, we aim to build cooperative relationships that prevent and mitigate negative impacts on society and the environment with all of our suppliers, ensuring that all transactions are fair, avoiding corruption, complying with the law and taking into account issues such as human rights.
In conducting procurement operations, we promote CSR initiatives in all business activities, including the procurement of raw materials, development, production, distribution, consumption, disposal, and recycling of materials and products.
(Establishment date: December 1, 2021)
In an effort to reinforce our organizational responsiveness with regard to CSR priorities throughout the global supply chain, we inform suppliers of the CSR Procurement Guidelines for the Procurement & Logistics Division and make efforts such as entering into agreements that incorporate the guidelines following mutual verification of the details with suppliers. The guidelines apply to all raw materials (excluding copper ores) and equipment. They consist of a Basic Procurement Policy, which sets out our responsibilities, such as fair trade, respect for human rights, legal compliance, ethical procurement, occupational hygiene, environmental protection, and information security, and in addition to these items, we require our suppliers to comply with other requirements stated in our CSR Procurement Standards, including fair business practices, the development of work environments, working hours, freedom of association, responsible raw material procurement, and the quality and safety of products.
To ensure the effectiveness of initiatives at our suppliers, we conduct supplier recruitment audits and supplier evaluations, which have been in place since April 2016, and conduct on-site audits as necessary (in fiscal 2022, we conducted on-site audits at one company).
Before starting transactions with new suppliers, we request that they conduct self-evaluations using a Supplier Self-Check Sheet. This self-check sheet consists of items that assess their initiatives on social responsibilities related to human rights (such as child labor, forced labor, and unreasonably cheap labor) and procurement (including negative environmental impact), in addition to general items such as quality, cost and delivery. The Procurement & Logistics Division assigns scores based on responses to the 12 evaluation items on the Self-Check Sheet, and determines handling based on the total evaluation score.
Based on our rules, we request that existing suppliers evaluate themselves every other year using the Supplier Self-Check Sheet, thereby checking the progress of their initiatives. In addition, when control is required for each item such as main raw materials, we use the "Supplier Evaluation Sheet" to conduct a comprehensive performance evaluation consisting of a total of 28 review items such as information security, quality control, delivery management, and prevention of corruption such as collusion, cartels, and abuse of superior bargaining position, and we respond to suppliers with poor performance evaluation as high risk. Suppliers with poor performance are identified as high risk.
We provide feedback on the results of these evaluations to suppliers, including items that need improvement, and periodically monitor them as needed.
In fiscal 2023, we collected Supplier Self-Check Sheets from 247 suppliers (44 new ones and 203 existing ones). We conducted screenings of all 44 new suppliers and periodic evaluations of 118 existing ones. Of the 162 suppliers screened or evaluated, there were no suppliers deemed high risk.
Starting fiscal 2024, we revised the existing Supplier Self-Check Sheet and added questions on policies, systems, initiatives, and corrective mechanisms for corporate ethics and environmental conservation, including items related to CSR, human rights, occupational health and safety, and prevention of corruption such as collusion, cartels, and abuse of superior bargaining positions at suppliers. With these changes, we will endeavor to ascertain the details of efforts being pursued by suppliers and monitor ESG and human rights risks in the supply chain. We will also encourage improvements by providing feedback to suppliers for which risks were identified.
The Mitsubishi Materials Corporation is an ensemble of companies operating under the composite profile of a comprehensive basic materials manufacturer. We provide resources, basic materials and energy indispensable to modern lifestyles, and adhere to its corporate philosophy of “For People, Society and the Earth.”
The Company's approach to CSR activities hinges on the idea of making this corporate philosophy a reality, through the sincere fulfillment of the obligations and expected roles that society places on corporate citizens, disclosure and proper explanation of the Company's activities to stakeholders, and the pursuit of a deeper level of two-way communication with stakeholders, in order to promote greater mutual understanding.
Mitsubishi Materials Corporation's CSR Guidelines are composed of a Basic Procurement Policy and CSR Procurement Standards. The Basic Procurement Policy clarifies philosophies and standards to be upheld by the Company in executing its procurement duties, while the CSR Procurement Standards clarify standards that the Company requests its suppliers (and their suppliers) to observe and uphold.
These guidelines were established based on the understanding that CSR procurement is not something that can be completed as an internal effort, and that it will only be effective if efforts are made across the entire supply chain.
Mitsubishi Materials Corporation promotes CSR initiatives in all business activities, including procurement of raw materials, development, production, distribution, consumption, disposal, and recycling of materials and products.
Mitsubishi Materials Corporation hopes that suppliers will work to extend fair transactions based on the purport and spirit of these guidelines to their suppliers, and will work together to build a resilient and competitive supply chain.

We procure copper concentrate, a raw material for copper products, primarily from the overseas mines in which we invest, to ensure a stable supply to smelters and refineries both in Japan and overseas. While this places us in the position of a non-operator not directly involved in mine management, as a company engaged in global procurement activities, we hope to fulfill our sustainable development responsibilities.
We place importance on dialog with indigenous peoples and members of local communities. For example, we assign specific staff members to participate in the advisory committees of mines in which we have a certain scale of interests.
Moreover, our Metals Company requires the mining companies to comply with CSR Investment Standards (if we are investing) and CSR procurement standards before we invest in them. We also check the status of compliance with those standards, for example through regular questionnaire surveys, and as necessary seek to understand and improve the situation. We also regard environmental preservation and respect for human rights as important matters to consider in management of the global supply chain and have incorporated these considerations into our business processes.
Protect the basic human rights of people impacted by our business operations. Consult with stakeholders regarding local community issues. Eliminate any involvement, either direct or indirect, with militia or other armed groups in areas of conflict where there are concerns regarding human rights violations.
Minimize the impact on cultural and natural heritage, identify and evaluate risks to biodiversity at every stage of our business, and develop and implement mitigation measures.
Understand and respect the society, economy, environment, culture and rights of indigenous people. Conduct social impact assessments with regard to indigenous people and provide appropriate compensation measures.
Verify if there are any disputes or lawsuits with the local community. Engage in consultation and dialogue to explain business plans.
Conduct environmental impact assessments (EIA) and obtain appropriate permits. Set out specific policies to reduce the environmental impact of mine development and operation.
Contribute to sustainable economic development at the regional and national level.
Mitsubishi Materials Corporation joined Zafranal copper mine development project in Peru with Canadian mining company Teck Resources Limited and its subsidiary.

MMC assigns personnel at the subsidiary established in Peru, and works with CMZ to continually monitor the situation on site and drive implementation of the project.
CMZ prizes the cultures, values, traditions and historical heritages of local communities, and has been establishing transparent and sincere long-term partnership with them. Accordingly, CMZ establishes opportunities for formal dialogue with local communities and additional stakeholders, and also conducts individual briefings and responds to their inquiries. CMZ has been building public trust while reflecting local opinions and needs through these activities.
While advancing legal processes to get approval of the Environmental Impact Assessment, CMZ is consulting with local communities. It is also undertaking environmental and social baseline studies in the project and related infrastructure areas.
The United States’ Dodd-Frank Wall Street Reform and Consumer Protection Act requires all companies listed in the US to disclose whether their products contain “conflict minerals,” defined as gold, tin, tantalum and tungsten, along with details of reasonable survey on producing countries and the survey results, in an effort to prevent minerals mined in the Democratic Republic of Congo (DRC) or its neighboring countries from being used to fund the activities of armed groups responsible for human rights violations and other acts of violence. Recently, the scope of conflict minerals has been expanded, particularly in EU countries, with consideration also being given to cobalt and silver from a broader perspective of responsible mineral procurement. In tandem with this trend, the OECD, SEC, and organizations such as RMI*1 and LBMA*2 have formulated guidance related to the issue of conflict minerals (responsible mineral procurement management).
As a responsible business operator smelting gold, silver, and tin, we have promoted initiatives to respond to these global requirements, and have formulated and disclosed related policies.
We also consider risks in the copper and lead supply chains, and conduct surveys of the producers and traders of these metals based on efficient due diligence standards.
Contact the Responsible Minerals Control Hotline if you identify any act in violation of the provisions of our Responsible Minerals Control Policy.
The Metals Company has pledged its support for a campaign to ensure a transparent flow of funds related to mineral resources, as promoted by the Extractive Industries Transparency Initiative (EITI)*1 since June 2011. We began preparations for tackling the issue of conflict minerals in 2012, obtained certification in August 2013 for our compliance with the London Bullion Market Association (LBMA)*2 gold guidance on avoiding use of conflict minerals and have had this certification renewed every year since. We have also begun operations and obtained certification with regard to silver.
Since February 2014, we have received annual certification of our conformance with the RMI*3 of RMAP*4 regarding tin.
Establishment date: 19th June 2013
Last revised date (Rev. 7): 1st December 2022
The Metals Company (hereinafter the “Company”) engages in bullion manufacturing for gold, silver and tin. The Company does not procure materials originating from high risk areas, such as conflict-affected areas, connected to human rights abuses, terrorist financing, money laundering and illegal trade. Also, the Company recognizes the importance of addressing Environment and Sustainability responsibilities for procurement of materials. To rigidly maintain this practice, the Company has adopted a control system that follows the London Bullion Market Association (LBMA) guidance for gold and silver, and the Responsible Mineral Initiative (RMI) Responsible Minerals Assurance Process (RMAP) for tin and undergoes regular audits by third-party bodies.
The Company’s responsible minerals control policy applicable to gold, silver and tin is as follows.

We endeavor to prevent quality issues by engaging in risk management activities for reducing quality risks at Group companies both in Japan and overseas. We aim to prevent quality risks from materializing and provide stable quality to customers.
In order to ensure that delivery time and cost are not prioritized over quality, we have established the order of priority for decision making in the performance of duties as SCQDE*. By repeatedly informing and educating employees, we are fostering an environment that encourages consistent judgments. The same concept is applied in product R&D, and is a fundamental principle in all decisions that require problem solving or response to potential risks. Furthermore, we have established a front-loading system guideline, whereby the design and development, manufacturing, quality assurance, research, and sales departments identify risks and problems to be considered at each stage from design to mass production, deliberate on improvements and countermeasures, and ensure the execution of new projects through expert review and customer evaluation. This process is reviewed by experts and evaluated by customers to ensure the execution of new business.
As a manufacturer, we are committed to providing our customers with safe, high quality products. We therefore strive to ensure the quality and safety of our products based on the precautionary approach, in addition to ensuring compliance with the law and other applicable regulations. We have also formulated a set of regulations for the control of hazardous chemical substances contained in our products. As well as thoroughly ensuring that we do not release any products containing hazardous substances to customers, including via Group companies, we are committed to disclosing product information as necessary.
We make every effort to guarantee safety when transporting products that require additional safety measures in transit, such as sulfuric acid.
Specific measures include ① avoiding contact with other substances, ② wear protective equipment when filling and unloading products, ③ take measures to prevent leaks or dispersal from containers, and ④ providing drivers with SDS clearly outlining measures in the event of an accident.
Providing safety information on our own products is vitally important, to ensure product safety further along the supply chain. We therefore attach Safety Data Sheet (SDS) to Mitsubishi Materials products so as to effectively disclose and convey information on chemical substances.
We have formulated a set of regulations for the control of hazardous chemical substances contained in our products, and continue to reinforce management and ensure legal compliance in relation to chemical substances contained in our products. In Japan, we register, maintain and manage chemical substances based on the Chemical Substances Control Law*1. Overseas, we successfully completed the registration of chemical substances in accordance with REACH regulations*2, which apply within EU regions, by September 2017, and currently maintain and manage those substances. Also note that new REACH regulations have come into effect in the UK (commonly known as UK-REACH) in response to the UK’s departure from the EU, and we are making the necessary preparations to comply. We are also gathering information on and responding to chemical-related laws and regulations in other countries as needed.
We provide Group companies with the latest information through quality liaison conferences and quality meetings, and give them advice on compliance with all applicable legislation.
We carry out reviews during four key stages of the R&D process, when exploring areas of R&D, conducting R&D and prototyping, conducting mass production trials, and commercializing products. While continually taking safety in our processes and products into account, we implement checks and careful examination regarding the use of hazardous chemical substances, compatibility with customer requirements and compliance with various laws and regulations. From the initial stages of the R&D process we repeatedly check these aspects.
The Group had declared November 1 of each year to be our Group-wide Quality Review Day so that the quality issues that occurred in 2017 will not be forgotten and the same issue will not occur again. In fiscal 2023, this was an opportunity to review quality issues by watching a video message from the CEO and a video of lessons learned from the series of quality issues. It is also an opportunity to once again verify that the products and services provided to customers at each site do not have quality issues. We have also implemented various initiatives, including the verification of the effectiveness of the measures for preventing the recurrence of complaints, and a review of the standards and procedures.
We operate in accordance with the “Fundamental Quality Provisions at Mitsubishi Materials Group” in order to enhance governance relating to quality. Under the quality provisions, we have formulated a Group-wide "Quality Policy" that aims to provide first-class products and to obtain customer satisfaction, and established and operate the "Quality Control Guidelines at Mitsubishi Materials Group" to complement the Group Quality Policy. We have established and are working to maintain our quality management, from design and development to production, shipping and sales, for the processes involved in quality improvement of products and services provided by us.
The Group handles a wide variety of products at its domestic and overseas sites, and it is important to share the latest information related to quality management. For this purpose, we periodically hold meetings of quality managers attended by representatives involved in quality control of our group. At these meetings, Safety, Environment & Quality Dept. provides and shares a variety of up-to-date information about our quality. Participants can then share examples of improvement at each site and hold group discussions on specific topics. The purpose is to deepen the understanding for quality representatives and share information and the outcomes from discussions at each site to enable further improvements.
We have also set up a Quality Liaison Conference comprised of the persons in charge of quality from Safety, Environment & Quality Dept., each in-house company, and others, in our efforts to enhance our governance system. At the Quality Liaison Conference, the progress and status of quality initiatives at each in-house company, including Group companies, are reported. The necessary information is then shared by participants.
Further, where necessary, Safety, Environment & Quality Dept. and the Company holds quality holds quality meetings that are aimed at sharing quality information. At quality meetings, we provide detailed support to each site, such as checking the status of quality management with each site individually and exchanging views. Quality audits are conducted as part of themed audits led by the Internal Audit Dept. The purpose of the quality audit is to confirm the lack of quality fraud and the implementation of effective quality initiatives based on objective evidence. It also aims to identify issues and improvements related to quality, and to provide an opportunity for the audited sites to make continuous improvements.
Given the reflection that crisis sharing within the Group was not working and a poor sense of ownership was seen when the quality issues occurred, quality training is conducted for each level of younger employees, middle employees and managers, to continue to change their mindset on quality. The quality management system (QMS) based on ISO 9001 is fundamental to our quality management and quality assurance. ISO9001 internal auditor training is conducted regularly for newly appointed auditors. In fiscal 2023, twelve classes were held with a total of 133 participants. Furthermore, we also held six classes aimed at maintaining and improving the auditing skill and capabilities for the experienced internal auditors. A total of 23 people participated in these classes.
Our Metalworking Solutions Company has 10 manufacturing sites in Europe, the United States and Asia, which manufacture high quality products in conjunction with our domestic sites. To accommodate the expansion of locally manufactured products overseas, we have continued efforts to provide technical instructions from domestic sites on equipment maintenance, production technologies, inspection standard and other matters. This initiative over a number of years has resulted in activities led by local employees overseas, e.g. kaizen (improvement) meetings and reviews of QC systems. Their motivation to acquire new skills and technologies is driving improvements in quality. We engage in activities to further improve quality, such as the raising of quality awareness and the improvement of quality documents through ongoing quality training.
Also, electronic components business, a part of Advanced Products Company, was expanded to Southeast Asia early and has transferred the production to the region. Today, in Southeast Asia, we have a total of five manufacturing sites (including subsidiaries and subcontractors) dedicated to the business, and they have worked closely with the Ceramics plant in Japan to develop production systems. The Copper & Copper Alloy Div. has a total of 12 sites in Europe, the United States and Asia, and is working to maintain and improve the level of quality management by strengthening coordination with Japanese sites and head office. In particular, to reduce customer complaints about product quality and maintain governance, we encourage the sharing of information and conduct a wide range of activities aimed at further raising awareness and improving the skills of local staff and personnel posted overseas, including quality supervisor meetings, small group activities and presentation meetings, quality audits conducted by the in-house company, and web conferences held on a timely basis.
As a result of the Group’s efforts to implement and strengthen prevention measures for recurrence in quality management, we have improved both quality awareness and control level across the Group and various measures have been disseminated across the Group. To prevent the recurrence of quality issues going forward, we will incorporate a series of measures to prevent quality issues into our quality management systems such as the systems that comply with the ISO 9001 standard, and continuously implement them.
Currently, as part of our "proactive quality management" efforts, we are also working to realize designs, facilities, and processes that prevent the occurrence of out-of-specification products. Each company and base sets quality targets and promotes various improvement activities to achieve them.
Since quality is the brand asset of our Group, we will continuously improve the level of quality through quality education and quality improvement activities, and continue to provide products that satisfy our customers.
