Hazardous Chemical Substances

Basic Philosophy

In association with the growing public awareness of environmental issues, regulations regarding hazardous chemical substances have become increasingly severe year by year. Taking appropriate measure to such concern has become vital to the continuation of business.
We have a three-step management system for handling substances of environmental concern: 1. Answering requests from customers, 2. Handling within the Group, and 3. Procurement from suppliers.
Naturally we ensure compliance with laws and fulfill customer requests. More than that, we aim to reduce the use and emission of substances of environmental concern so as to minimize their effect on the environment and human health.

Answering Requests from Customers

With the reinforcement of regulations on chemical substances contained in products, requests from customers in the automobile, electrical and electronics industry regarding improved compliance are increasing. The REACH Regulation of the EU has triggered an increase in the status of chemical substances contained in products; we are taking all the appropriate measures including submission of Non-Containing Declarations, submission of various data with IMDS, AIS, etc., and handling investigations and audits regarding our management systems.

Handling within the Group

To respond appropriately to increasingly strict chemical substance regulations worldwide, we perform non-containment management for products and usage management within plants.
For hazardous chemical substances, we set hazard rankings according to toxicity and the strictness of regulations, and establish handling standards for each rank.
From here on out, we will work toward substitution of hazardous chemical substances and the strengthening of management, to assure compliance with laws and with the demands of customers.

Management System

Hazard Rank

Rank Handling standard Substances covered
Prohibited substances Use is prohibited. Substances prohibited from use or strongly restricted by regulations.
Restricted substances Safer substitutes will be sought, while making efforts to reduce the use of current substances. Hazard level and toxicity are equivalent to prohibited substances, but an immediate changeover is impossible due to its special characteristics.
Monitored substances Supplies need to be examined to find existence / non-existence of applicable substances. Those not prohibited or restricted but that require monitoring.

Management of PRTR substance

Aiming at optimized management, the respective divisions have ensured to identify and totalize PRTR substances for clarifying handling volume, release volume, and transfer volume.

Procurement from Suppliers

To manage chemical substances contained in products appropriately, it is imperative that we gain the cooperation of our suppliers. For this reason, we request in our Green Procurement Guidelines that our suppliers not use hazardous chemical substances banned by NGK SPARK PLUG CO., LTD. We designate suppliers that meet our system and material standards as Green Suppliers. In collaboration with our Green Suppliers, we promote appropriate management of hazardous chemical substances.
