Chemical Management

Basic Approach

The Ryohin Keikaku Group strives to prevent and reduce global environmental pollution by considering the impact of chemical substances on the human body and the natural environment in order to develop safe products and protect the health and safety of customers, production partners, employees and local communities. To this end, the Group complies with all relevant laws and regulations, prohibits the use of certain hazardous chemical substances, and ensures thorough management of chemical substances in both its final products and manufacturing processes.

Goals

We comply with laws and regulations and work to reduce our impact in order to conserve the global environment.

• We appropriately handle chemicals in our products and in manufacturing processes.
• We comply with all applicable environmental laws, regulations and standards.
• We prohibit the use of substances suspected of being harmful.
• We inspect products regularly to ensure that compliance related to prohibited or restricted substances is met.

Management System

The Ryohin Keikaku Group manages chemical substances in accordance with its environmental management system.

Management of Substances on the Restricted List for Textile Products

Ryohin Keikaku is committed to managing and reducing the use of harmful substances in textile products as part of its environmentally and socially responsible product development policy.
Ryohin Keikaku is a member of the Apparel and Footwear International RSL Management (AFIRM) Group, which aims to reduce the impact and use of harmful substances in the global supply chain.
By requiring our employees and production partners to comply with the MUJI Product Restricted Substances List, which incorporates our own standards in addition to the AFIRM Restricted Substance List (RSL), we are committed to eliminating chemical substances of concern for human health and to ensure safe, reliable manufacturing and quality control. We also conduct sampling inspections based on these standards to reflect the results in actual operations. Going forward, through our participation in AFIRM we will continue to monitor industry trends and the initiatives of other companies, as well as revise the MUJI Product Restricted Substances List in a timely manner.

Initiatives for Perfluorinated and Polyfluorinated Chemicals (PFAS)

PFAS are chemicals primarily used in textile products to provide durable water-repellent and other functions.
Due to their high bioaccumulation in the human body, some PFAS may adversely affect the human body or be carcinogenic. In addition, PFAS do not decompose easily in the environment and have been identified as environmental pollutants in soil, water, etc.
In many countries, long-chain polyfluorinated chemicals like PFOS and PFOA, classified as C8 chemicals, have been banned due to the aforementioned properties. Furthermore, restrictions on all PFAS have recently been expanded in the European Union and the United States.
Ryohin Keikaku has restricted and is actively working to eliminate the use of all PFAS during the production process for textile products manufactured after 2023/8.

Code of Conduct for Production Partners

Ryohin Keikaku requires its contract production partners to safely manage chemical substances and prevent water and air pollution in accordance with our Code of Conduct for Production Partners. Restricted substances are listed in the Ryohin Standards, which specify our internal quality standards and are made available to production partners. We ensure that manufacturing processes do not involve the use of any prohibited chemical substances based on our standards. We abide by the laws and regulations of each country or region regarding designated chemical substances. We monitor emissions and report them to the respective governments as required by the laws and regulations.

Environmental Audit of Production Partners

Ryohin Keikaku only contracts with production partners who pledge to adhere to the Code of Conduct for Production Partners. To ensure that our partners follow the code of conduct and its policies, we enlist the services of a specialized third-party organization to carry out environmental audits and monitor working environments. If any of our partners fail to meet our established standards, we work with them to take the necessary corrective actions.
The environmental audit covers a wide range of aspects, including chemical substance storage and management, establishment of handling procedures, and proper treatment and monitoring of hazardous substances, wastewater, gases, and other related matters.
