Responsible Care Initiatives

Quality Initiatives

Ensuring Continuous Improvement of Quality

Our basic policy related to quality is to provide products and services that fully satisfy our customers while earning their trust. We also work to maintain or improve our quality levels.

Customer satisfaction initiatives

Quality control convention

All our plants and all Group companies inside and outside Japan engaged in manufacturing and logistics have introduced quality management systems. We implement our quality assurance initiatives from the customer's perspective from the product development stage through manufacturing and delivery.
We are dedicated to the continuous improvement of our quality management system to ensure our customers are satisfied with the stable high quality of our products and services.

Promoting initiatives to address quality issues

We respond quickly to any complaints or inquiries from customers concerning our products and share information throughout the company by compiling it into a database to visualize the progress of the response. At the same time, we are preventing quality issues from occurring through company-wide distribution of case studies.
We also issue monthly reports on claims and complaints that occurred at our Group companies, thereby ensuring sharing of information and preventing the emergence of quality problems.

Supply chain initiatives

Nippon Shokubai promotes initiatives to ensure supplies of safe and reliable products throughout the entire supply chain, from procurement of raw materials to manufacture and sales of products. In accordance with our regulations for green procurement management, we have independently assigned substances that are regulated or highly hazardous to two categories: "prohibited substances" and "restricted substances." We are promoting the development of green products and the procurement of raw materials with low environmental impact while controlling the inclusion of such substances in our products. For information transmission sheets, we have introduced chemSHERPA, which was developed under the guidance of the Ministry of Economy, Trade and Industry.

Toward gaining greater public trust

We have established quality management systems and ensured the safety and reliability of our products. In response to growing social demand for product quality and reliability, the quality assurance segment of our Head Office has conducted quality audits of our plants and Group companies to check the quality assurance systems and the status of quality management at all production sites.
In fiscal 2018, executive management conducted RC inspections on the theme "preventing quality troubles and ensuring quality governance." The inspections confirmed that at both the Himeji and Kawasaki Plants, past problems have been thoroughly reviewed and communicated throughout the company, that the quality system incorporates an adequate mechanism for preventing irregularities, and that the quality awareness is shared among the employees to ensure the quality-related governance at the plants.
We participated in the formulation of the Guidelines for Enhancing the Quality Assurance System, which were released by the Japan Petrochemical Industry Association in response to recent inadequate quality incidents that had occurred at other companies. While familiarizing the entire Group with these Guidelines, we conduct quality audits and RC inspections to check for any inappropriate behavior related to quality.

[Guidelines for Strengthening the Quality Assurance System (structure)]
  1. Strengthening the quality assurance system by top management
  2. Further awareness improvement of all employees (including top management) about quality assurance
  3. Preventing occurrence of inadequate or inappropriate incidents related to quality
  4. Response to inadequate or inappropriate incidents if they occur
  5. Connecting quality data

Introducing products with halal certification

We have acquired halal certification from the Japan Muslim Association for the products described below, which were approved by the Shariah Research Institute of Takushoku University.
Parts of Southeast Asia, most notably Malaysia and Indonesia, are home to many Muslims, and demand for halal-certified ingredients and production processes from food-related businesses has been increasing. In response to this situation, we have acquired halal certification for products for which acquisition of the certification is strongly urged by customers.

halal certification Note: The products for which we have acquired halal certification as of April 1, 2019 are
succinic acid, succinic acid disodium,
maleic anhydride,
AQUALIC™ FH (a thickener),
AQUALIC™ MH (a feed binder) and
AQUALIC™ IH (a flocculant).


This shared system for transmitting information about chemicals contained in products to supply chains was developed under the leadership of the Ministry of Economy, Trade and Industry in Japan. Full-scale utilization began in April 2018.
Halal Certication
A certification with religious relevance, granted by the relevant organizations when certain standards are satisfied, for products and services targeted at Muslim customers.
