Manage chemical substances

Murata's chemical substance management

Looking toward the realization of sustainable social systems, Murata strives to provide products with minimal impact on the global environment.
Guided by the Global Framework on Chemicals – For a Planet Free of Harm from Chemicals and Waste (GFC), and in addition to complying with laws such as the RoHS Directive and the REACH Regulation, we have established internal standards based on global trends in environmentally hazardous substances and customer requests. Through the targets and policies shown in the table below and the management system shown in the figure below, we are actively promoting initiatives to reduce or prohibit environmentally hazardous substances contained in our products and to research and develop alternative substances with lower environmental impact.

  • We continued to revise our internal standards and completed the update in October 2025. With regard to the substances recommended for elimination at Stockholm Convention POPRC20, we have completed the elimination or substitution of chlorpyrifos, medium-chain chlorinated paraffins (MCCPs), and C9–C21 long-chain perfluorocarboxylic acids.
  • We have begun discussions on selecting regulated substances and revising our internal standards, in preparation for the next update of those standards in October 2026. Draft revisions are formulated based on trends in national regulations and customer requirements, through discussions with our technical departments and validity assessments, and are finalized after regular discussions with each business unit.
  • While PFAS substances have useful properties, some have been identified as raising concerns, such as resistance to degradation and environmental persistence. Murata has eliminated specific PFAS substances of high concern — including PFOS and PFOA — ahead of international conventions and national laws, and is also strengthening company-wide management of other PFAS substances. By 2025, we had completed substance identification and assessment of actual use. Under responsible chemical management and governance, we continue working to reduce impacts on people and the environment.
  • Set as a target that does not change each fiscal year

Management system

System for designing and evaluating products so that they do not contain environmentally hazardous substances exceeding regulated values (product assessment)

Product
development

System for obtaining material composition information from suppliers so that only certified materials are purchased (green procurement)


Procurement

System for verifying and evaluating manufacturing equipment, etc., so that environmentally hazardous substances do not become attached to products


Manufacturing processes

System for ensuring that products that contain banned substances cannot be shipped to customers that do not approve the shipment of such products


Shipments

We are also responding preemptively to the revision of laws relating to environmentally hazardous substances.
The Stockholm Convention on persistent organic pollutants (POPs) commonly referred to as the POPs Convention, is a framework for international cooperation aimed at reducing or eliminating typical substances of concern. “Dechlorane Plus” was newly added to Annex A (Elimination) at the 11th Conference of the Parties (COP11) held in May 2023. Since the early 2000s, Murata has been focusing on the environmental concerns of fire retardants including chlorine and has voluntarily engaged in restricting its use, and as a result, promptly finished eliminating or replacing “Dechlorane Plus.”

In addition to managing the chemicals contained in its products, Murata also manages the chemicals used in its manufacturing process.

Management of environmentally polluting substances

At Murata, we record data on the chemical substances we use in our Japan plants in a database, and we use a system that allows us to easily understand and manage the status of use of individual chemical substances.

We use this system for the discharge and transportation calculations required by the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (PRTR Law).

Of the 515 classes of substances that are subject to reporting under the terms of this law, in its Japan operations between April 1, 2025 and March 31, 2026, Murata used one ton or more of 38 classes of substances including toluene and nickel. The amounts used are shown below.

Managing cleaning chemicals to reduce worker exposure risk

It is known that some chemical constituents used in manufacturing processes have detrimental effects on the human body. In particular, chemicals used for cleaning purposes raise concerns about the risk of adverse health effects, as workers may be exposed to them at high concentrations over long periods.
In general, risk-reduction measures follow a hierarchy of controls, in order of priority: elimination, substitution, engineering controls, and administrative controls.
Murata has long worked to reduce worker exposure risk by maintaining safe work environments through engineering controls, such as local exhaust ventilation, and by implementing administrative controls, such as the wearing of personal protective equipment.
In addition to these efforts, since FY2022, we have been advancing initiatives that incorporate the concepts of elimination and substitution in order to achieve further reductions in risk. Adopting the approach of the Clean Electronics Production Network (CEPN), an international initiative for chemical substance management, we have set an internal standard prohibiting the use and inclusion of nine high-exposure-risk substances* used for cleaning purposes.
As of the end of FY2025, for the target chemicals that can be substituted using currently available technology, we have completed the phase-out of their use and inclusion and the transition to alternative substances.
Going forward, we will continue technological development aimed at elimination and substitution while maintaining the engineering and administrative controls already in place, taking a comprehensive approach to reducing exposure risk.

Green procurement

Murata recognizes that it is crucial to protect and conserve the global environment to achieve sustainable development in the human society, and is working to promote environmental load reduction (E), securing health and safety (H and S), and disaster prevention activities based on the “EHS Disaster Prevention Policy.” The Procurement Department promotes “Green Procurement” where materials with low environmental load are procured, and the understanding and cooperation of suppliers are necessary to achieve this. By clarifying requirements for suppliers through the “Green Procurement Standards” issued in October 2005, Murata aims to establish a long-term relationship with suppliers that agree to these standards.
Specifically, we are promoting “Green procurement” based on the following 5 Steps.

Step 1: Murata Group Environmental Policy Establishment
In order to reduce the environmental load of products, "green procurement" is required to procure materials with a low environmental load.
When beginning businesses with suppliers, Murata distributes the "Green Procurement Standards" that includes details such as Murata's approach to green procurement and requirements for suppliers, and promotes green procurement with the understanding and cooperation of suppliers. The latest version is distributed through our system for suppliers and supplier dedicated portal when revisions are made.

Step 2: Finalizing contracts with suppliers
Once suppliers have understood Murata’s contained-substance standards as outlined in the "Green Procurement Standards", they are required to submit the “Agreement to Environmental Protection Measures.” This is one of the criteria used to determine whether or not to start businesses with new suppliers.

Step 3: CMS audit/evaluation execution
When conducting new business, we ask that our partners also address global environmental problems such as climate change and environmental pollution based on the "Murata Group Sustainable Procurement Guidelines." Moreover, in addition to asking to verify the certification status of suppliers under environmental management systems (ISO 14001, etc.), we audit the state of chemical substance control at the manufacturing sites to determine whether we can do business with a supplier. Once we begin doing business with a supplier, we periodically evaluate how they are managing chemical substances and working toward reducing their environmental load. Suppliers who receive a poor evaluation are requested to make improvements or receive guidance through on-site audits.

Step 4: Green level investigation execution
Murata implements “Green level investigation” for each item before adopting materials.
As the basis for this process, Murata uses its proprietary technical standard, which stipulates bans and reductions in the use of substances in accordance with legal regulations and customer requirements.
Based on the contained-substance information for materials supplied by our suppliers, our specialist staff review and certify them, and register the certified items in the environmental information database.

Step 5: Establishment of a system that enables ordering of certified materials only (Purchase Order Checking System)
We have introduced a “Purchase Order Checking System” that enables ordering of only materials registered in the environment information database and established a system to ensure that only certified materials are brought into Murata’s facilities.
