On 23 January 2025, Japan’s National Institute of Technology and Evaluation (NITE) published the English version of the list of 169 chemicals classified according to the provisions of the Globally Harmonized System for Classification and Labelling (GHS) on its portal. NITE released the updated list for FY 2022 on the portal on behalf of the Ministry of Health, Labour and Welfare (MHLW), the Ministry of Environment (MOE) and the Ministry of Economy, Trade and Industry (METI) - the three ministries responsible for GHS classification in Japan. 

Previous Update 

Earlier, on 21 June 2024, NITE published the GHS list for 160 chemicals (FY 2023) on its portal. More details can be found here. 

Insights from the Update 

The FY 2022 list includes 47 entries for newly classified substances and 122 entries for revised GHS classified chemicals. This list covers classifications from 1 April 2022 to 31 March 2023. NITE also provided the detailed information of the classified chemical for: 

• Hazard Class 

• Pictogram 

• Signal Word 

• Hazard and Precautionary Statements 

• Classification Details 

• CAS and Identification Numbers 

• Reference Data 

Obligations for Companies 

Companies are advised to have updated GHS information available when preparing labels or Safety Data Sheets (SDSs). However, it’s not mandatory to use the classification provided. Companies may use alternative data or test results which are not covered by the MHLW, MoE and METI.

On 10 January 2025, Japan’s National Institute of Technology and Evaluation (NITE) added ingredients used in cosmetics to the country’s Chemical Risk Information Platform (NITE-CHRIP). As a government agency, NITE has been designated to provide chemical management information. NITE added cosmetic ingredients to the CHRIP for the first time in collaboration with the Japan Cosmetic Industry Association (JCIA).   

NITE-CHRIP Database 

NITE-CHRIP is a publicly available, free database that allows users or businesses to search for national and international legislation related to chemical substances. The database also provides summaries of compliance procedures along with chemical hazard or risk assessment information. NITE-CHRIP lists more than 250,000 entries, most of which include CAS data available in both Japanese and English.   

Regulatory Classification of Cosmetic Ingredients 

Standards for the use of cosmetic ingredients are regulated under the Act on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices (PMD Act). 

Cosmetic ingredients are classified into two lists: 

• Negative List (Appendix 1): Includes substances that are prohibited in cosmetics (excluding Class I and Class II Specified Chemical Substances under the Chemical Substances Control Law (CSCL)). 

• Positive List: Includes Appendices 2-4 with restricted ingredients, restricted ingredients of preservatives, and restricted ingredients of UV absorbers respectively. 

Obligations for Companies 

Companies dealing with such cosmetic ingredients in Japan are required to comply with the standards for cosmetics under the PMD Act.

Update: On 30 January 2025, the Japanese government notified the WTO that the proposed revisions to food additive standards under the Food Sanitation Act became effective on 23 January 2025.  

Original Text: 

On 5 November 2024, Japan’s Consumer Affairs Agency (CAA) notified the World Trade Organization (WTO) of proposed revisions to food additive standards under the Food Sanitation Act. These updates will establish specifications and standards for rubber and amino acid-sugar reaction product and revise standards for cyclodextrin. The standards provide definitions, descriptions, identification methods, purity and ash or assay content.  

Background   

Under Article 12 of the Food Sanitation Act 1947, designated food additives may be sold as authorized by the Prime Minister. However, Article 13 of the Act establishes specific standards for food additives in accordance with the Ministry of Health and Welfare Public Notice No. 370 of 1959, which prohibits the sale of such additives unless they meet the requirements.   

New Food Additive Standards  

New standards for the following food additives will be established:  

Revised Standards for Cyclodextrin    

Currently, the standards for branched cyclodextrin are limited to powdered products. In addition to powdered products, liquid products will also be subject to revised standards.   

Comment Period and Enforcement Dates   

The 60-day comment period ended on 4 January 2025.

Regulatory Background 

According to Article 594-2 of the Industrial Safety and Health Regulations which came into force on 1 April 2024, the use of impermeable protective equipment is mandatory when handling certain substances. This regulation ensures that workers are adequately protected from direct exposure to hazardous chemicals, thereby reducing the risk of skin irritation and other health complications. 

Obligations for chemical handlers 

Employers and workers handling chemical preparations above the specified cut-off value must use impermeable protective equipment, such as gloves and protective clothing, to prevent direct skin contact with hazardous substances.  

Key details of the updated list of skin irritants 

The updated list contains 1210 entries of chemicals with data compiled as of 9 November 2023. The list includes information about:
