Responsible Mineral Procurement

Procurement Management

Responsible Mineral Procurement

The considerations for responsible minerals procurement are heightened lately, following the enactment of The US Dodd-Frank Wall Street Reform and Consumer Protection Act in July 2010. Especially the concern regarding conflict minerals (tin, tantalum, tungsten, and gold commonly known as "3TG") that are mined from the Democratic Republic of the Congo and surrounding areas and used by an armed group or anti-government force as a source of funds.
According to the Article 1502 of The Securities and Exchange Commission (SEC), companies listed on securities exchanges in the US are required to investigate/report usage conditions regarding conflict minerals that are mined from the Democratic Republic of the Congo and surrounding areas that are used by an armed group or anti-government force as a source of funds. EU Conflict Minerals Regulation will come into effect in 2021, The need and importance of responsible mineral procurement are expected to increase in the future. Faced with this new situation, ROHM Group sees sincerely facing important risks such as human rights violations in the supply chain to be its corporate social responsibility, and will make efforts to manage and mitigate these risks.


From the standpoint of the protection of human rights, ROHM Group makes it a rule not to use conflict minerals (tantalum, tin, tungsten, and gold) in target countries, where the conflict minerals are used as a source of funds by an armed group that has violated human rights in these areas, as materials for the Group's products.

Furthermore, we request that suppliers respect ROHM's policy not to use such minerals as materials for our products and to make efforts to comply with this policy.

[ROHM Group Compliance Rules]

  • ROHM Group does not use conflict minerals that finance armed groups.
  • ROHM Group will work to procure from conflict-free smelters certified by RMI, etc.
  • In the unlikely event that we discover the use of conflict minerals to fund armed groups, ROHM Group will take immediate corrective action.
  • RMI : Responsible Material Initiative

2.Management System

ROHM Group's supply chain management division plays a central role in working with business units and suppliers to promote responsible mineral sourcing. He is also a member of JEITA, an industry group working to achieve responsible mineral procurement.We perform due diligence through CMRT (*) research to identify risks. Then, the mineral procurement status is reported to the management at the end of each fiscal year.In addition, we formulate a responsible mineral procurement plan based on company rules every year and manage its progress on a monthly basis.

3.Responsible Mineral Procurement Survey

To ensure that customers can use ROHM products with peace of mind, the SCM Division plays a central role in conducting the following assessment processes in accordance with OECD Due Diligence Guidance(*).

[Mineral Procurement Survey Process]

STEP1 : Construction of a Management System

  • ROHM Group's Responsible Mineral Procurement Policy have been publicized internally and externally through the CSR Guidebook and ROHM website.
  • Based on internal regulations, we have established a system to investigate the minerals contained in our products and assess risks in cooperation with relevant divisions in Japan and overseas.
  • We ask suppliers for their support for ROHM Group's responsible mineral procurement activities and submit written consent.
  • Appropriate management and storage of survey result information based on internal regulations.
  • When requesting an investigation, we inform suppliers that they use a refinery certified by RMI.

STEP2 : Identifying and Assessing Risks in the Supply Chain

  • We extract the parts that need to be investigated from the parts that we purchase every year.
  • We conduct a supplier survey using the CMRT and CRT provided by RMI. The survey will check for 3TG and cobalt content, country of origin and smelter.
  • For smelters, check the latest list of RMI certified smelters to identify uncertified smelters.

STEP3 : Strategic Planning and Operation to Address Identified Risks

  • If an uncertified RMI refinery is identified, ask the supplier for corrective action.
  • For smelters pointed out by customers as “non-certification concerns”, we will confirm the points pointed out and notify the supplier of the details of the risk. Discuss appropriate measures (such as smelter reexamination) with the supplier.

STEP4 : Annual Report of Activities

  • Report the status of due diligence on the website.

[3TG Survey Results]

In fiscal 2020, ROHM Group conducted a mineral survey of the materials it purchased. We carefully examined the responses to the questionnaire, and confirmed the responses to those suppliers who found deficiencies, in order to improve the reliability of the responses.

  • Suppliers surveyed : 203 companys
  • Suppliers who obtained survey responses : 203 companies, 100%
  • Specified smelters : 263 companies for all minerals (Of these, 222 have obtained RMAP(*) certification for RMI.)
3TG Survey Results (FY2020)
Gold Tantalum Tin Tungsten Total
All smelters 135 35 54 39 263
Number of CFS 105 35 46 36 222
CFS certification rate 78% 100% 85% 92% 84%

As of 2020, investigations have not confirmed the use of conflict minerals that finance armed groups.
ROHM will take corrective measures as soon as possible in the event that the use of conflict minerals, which are the source of funds for armed groups, is discovered in ROHM Group products.

[Cobalt Procurement]

Cobalt is used in lithium-ion batteries, which are essential for electric vehicles, mobile phones, and laptops. The largest producer of cobalt in the world is the Democratic Republic of the Congo (DRC), which is mined using machine and human resources. In recent years, concerns have been raised about unsafe working conditions and child labor.
ROHM's CSR Procurement Guidelines establish labor and ethical policies that include the prohibition of all forms of forced labor and child labor. ROHM will promote responsible procurement of cobalt to increase the transparency of the cobalt supply chain.
Using the CRT provided by RMI, we conduct surveys every year to confirm the cobalt content, the country of origin, and the location of the smelter.

[Results of Cobalt Survey]

  • Suppliers surveyed : 4 companies
  • Suppliers obtaining survey responses : 4 companies, 100%

4.2021 Targets

ROHM Group has set a goal of 2021 to "build a system that can comply with laws and regulations related to responsible mineral procurement."In the near future, supply chain transparency will become mandatory, and managed risks (environmental destruction, human rights issues such as child labor, business integrity, etc.) and controlled minerals are expected to expand further.Even in such a situation, in order to promote responsible mineral procurement, it is essential to strengthen due diligence, educate and educate suppliers, and establish and improve the system to promote these activities. Moreover, the achievement of responsible mineral procurement cannot be achieved without the efforts of the entire supply chain. Therefore, we have set the above goals in 2021. We will continue to carry out mineral surveys with the cooperation and trust of suppliers, and strive for two-way communication such as grasping the procurement status and sharing information.

5.Cooperation with Industrial Associations

ROHM is a member of the JEITA Responsible Mineral Procurement Study Group, which was established in 2012 with the aim of collaborating with industry and establishing research methods for responsible mineral procurement.
Every year, we participate in responsible mineral surveys held by the Responsible Mineral Procurement Study Group, and work to penetrate the industry supply chain. In order to respond to growing international demand, we are promoting responsible procurement activities through industry activities, such as encouraging smelters that have not received RMAP (Refinery Audit Protocol) certification to undergo RMAP audits.
