Quality assurance department

Make a final confirmation on product taking into account the product characteristics and the customers use
We have enhanced the accuracy of quality measurement by advancing the automation of measurement processes to eliminate variations derived from quality measurement personnel, sample preparation, and measurement procedures. In addition, measurement results are stored and shared in the database to prevent typing errors when creating inspection tables and labels.

Almost all of the Group's manufacturing bases, both domestic and overseas, have obtained certification of the quality control systems such as ISO 9001, IATF169491, etc.

  • 1 IATF16949
    It is a quality management system for automotive industry.

Quality Audits and Support

To solve the zero quality problem, the claim and complaint information from the customers are closely examined. In internal quality audits, we check quality control activities and quality control systems to ensure that necessary improvements are being implemented properly.
Also, quality control activities are evaluated according to two different viewpoints, which are the customers' viewpoint and quality cost viewpoint. We work to find the root cause of quality issues and to make an effort toward the recurrence prevention.
Furthermore, Six Sigma1 programs are deployed on a company-wide basis in order to improve the quality level.

  • 1 Six Sigma programs
    Quality improvement method developed by Motorola in the 1980s. Focused on processes where quality variation appears, it is designed to minimize variation within the processes and thereby reduce the incidence of quality defects. This approach has been adopted across the Group.

Product Safety Control

Product safety is being managed from product development to delivery based on internal regulations.
Regarding the safety of new chemical substances, risk assessment and confirmation for environment and health is performed at the development stage.
Regarding the development of new chemical substances, we  focus on products as well as their manufacturing technologies which do not use hazardous substances that have been designated by the Industrial Health and Safety Law and Chemical Substances Control Law1, as well as the EU RoHS risk assessment Directive2. Furthermore, we ensure to submit necessary notifications and reports according to laws and regulations.
Customers are offered information such as product hazards and risks in the form of SDS3 in order to ensure proper transmission of information to the value chain.
In addition, customers are requested to handle products safely by complying with laws and regulations, installing abatement equipment, wearing protective equipment, etc through SDS.
As a product transportation safety measure, we issue Yellow Cards4 and/or Container Yellow Cards5 that are affixed to containers. Furthermore, pictorial indication of hazard and harm is also implemented in accordance with GHS6.

In accordance with the Industrial Safety and Health Act, we also implemented pictorial indication of hazard and harm in accordance with GHS6 on product containers and packaging.


  • 1 Chemical Substances Control Law
    Short for "Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc." A law intended to prevent environmental pollution by chemical substances that can be harmful to human health or to ecosystems.
  • 2 RoHS (Restriction of the Use of Certain Hazardous Substances) Directive
    EU directive on restricting the use of certain hazardous substances in electrical and electronic equipment.
  • 3 SDS (Safety Data Sheet)
    SDS lists the physical and chemical properties of the chemical substance together with harmfulness and emergency response procedures. Designed to promote safer use of chemical substances and prevent accidents and incidents, SDS are supplied by manufacturers, importers and distributors to customers at the point of sales or shipment.
  • 4 Yellow Cards
    The yellow cards are cards on which all relevant information on treatment required in case of an accident during transportation of chemical substances is described.
    The cards are handed to the transport contractor to be brought by tanker lorry or other means at the time of transportation.
  • 5 Container Yellow Cards
    The standard yellow card system is not suitable for use with mixed cargoes and small-lot deliveries. Instead, each container carries a label displaying safety information such as UN number of chemical name and emergency response procedure number.
  • 6 GHS (The Globally Harmonized System of Classification and Labeling of Chemicals)
    Internationally standardized system of classification and labeling of chemicals.
