On December 25, 2025, the Japanese Standards Association (JSA) issued the revised Japanese Industrial Standards JIS Z 7252:2025 and JIS Z 7253:2025 for public consultation. These updates are intended to bring Japan’s chemical classification and hazard communication framework into line with the 9th revised edition (2021) of the UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
JIS Z 7252:2025 – GHS-based Classification of Chemicals
This standard defines how chemicals are classified for physicochemical, health, and environmental hazards in accordance with GHS. It covers:
· Information requirements and procedures for classification
· Classification principles, criteria, and processes
· Use and quality of available data and test methods
· Special considerations for mixture classification
· Bridging principles for health and environmental hazards
Originally issued in 2009 and revised in 2014 and 2019, this marks the third revision. Drafted by the Japan Chemical Industry Association (JCIA) and JSA, reviewed by the Japanese Industrial Standards Committee, and approved by the Ministers of Health, Labour and Welfare and of Economy, Trade and Industry, it formally replaces JIS Z 7252:2019.
JIS Z 7253:2025 – GHS-based Hazard Communication (Labelling and SDS)
This standard specifies how GHS hazard information must be communicated via labels, workplace labelling, and Safety Data Sheets (SDS), which are essential for chemical risk prevention and emergency response. It addresses:
· Required hazard information and communication methods
· Label content and determination procedures
· SDS structure and content
First issued in 2012 and revised in 2019, this update follows the same drafting, review, and approval process and supersedes JIS Z 7253:2019.
Implementation and Transition
Both revised standards will become mandatory on December 25, 2030. A transition period of about five years has been provided, during which JIS Z 7252:2019 and JIS Z 7253:2019 may continue to be used for classification, labelling, and SDS preparation until December 24, 2030.
The parallel revision of JIS Z 7252 and Z 7253 further aligns Japan’s chemical safety regime with international best practices. The extended transition period allows companies sufficient time to update classifications, labels, and SDS, and JSA encourages early preparation to ensure timely compliance.
