On 18 October 2024, Japan’s Ministry of Economy, Trade and Industry (METI), Ministry of Health, Labour and Welfare (MHLW) and Ministry of Environment (MOE) jointly released a notice seeking toxicity information for ethyl hydrogen sulphate and 26 related chemicals. 

Based on the data submitted by the companies, these 27 chemicals will be designated as either Priority Assessment Chemicals (PACs) or General Chemical Substances under the Chemical Substances Control Law (CSCL). The designation will be enforced from the beginning of FY 2025.  

Council Negotiation in January 2024 

In January 2024, METI, MHLW and MoE jointly held a council negotiation for the delisting of ethyl hydrogen sulphate (Serial Number: 244) from the PAC list and the revision of the assessment unit. The Council concluded that delisting will occur at the end of FY 2024 and will depend on the results of the assessment units which involve toxicity data along with other information. Once delisted from the PACs list, the CAS number will be revised in the notification.  

Priority Assessment Chemicals  

The possible negative effects of Priority Assessment Chemicals (PACs) have led to heightened monitoring of these substances. According to the Chemical Risk Information Platform of the National Institute of Technology and Evaluation (NITE), 225 chemicals are now classified as PACs.  

Companies that manufacture or import these compounds in quantities of more than one tonne per year are required to submit annual reports to ensure compliance with METI laws and to promote overall safety and accountability in the handling of chemicals. 

Company Obligations 

Companies are required to submit the following information for ethyl hydrogen sulfate: 

• CAS Registry Number 

• Toxicity information (algae growth inhibition test, daphnia acute immobilization test and fish acute toxicity test) 

• Hazard assessment information 

• Physical and chemical properties 

Submission Procedure and Deadline 

Companies can submit the relevant information to METI by 22 November 2024, either mail or in-person. According to the results of the screening evaluation conducted by new assessment units, ethyl hydrogen sulphate will either be designated as a PAC at the start of FY 2025 or treated as a general chemical substance.

On 27 September 2024, Japan’s Ministry of Health, Labour and Welfare (MHLW) approved amendments to the Standards and Criteria for Foods, Food Additives. This amendment revises the positive list of food contact materials (FCMs) under the Food Sanitation Act. 

This amendment will revise the usage provisions of 4 polymers in Table 1 and add 13 new additives to Table 2 of the FCM positive list. There are now 840 entries on the list.    

Public Consultation in May 2024 

Before approving the amendment, the MHLW held a public consultation from 24 May 2024 to 22 June 2024 to gather feedback on the proposed changes to the FCM positive list. This consultation specifically addressed revisions to the polymer use provisions and the addition of new additives, which were included in the final amendment. 

Standards and Criteria for Foods, Food Additives 

The Standards and Criteria for Foods, Food Additives contain requirements and guidelines for foods, milk and milk products, food additives, apparatus, and containers and packaging regulated by the Food Sanitation Act and other laws. The MHLW regularly revises these standards to keep them up to date and to protect human health and the environment. 

Japan’s Positive List of FCMs 

For synthetic resins used as primary materials in food utensils, containers, and packaging, the amended Food Sanitation Act introduced a positive list system on 1 June 2020. Only materials deemed safe and specifically included in the Positive List are permitted for use, which by default forbids the use of synthetic resin materials. 

The MHLW released the Japanese version of FCM Positive List (containing 827 entries) on 30 November 2023, followed by the English version on 25 December 2023. Details can be found here.  

Enforcement Date 

The amendment came into effect on promulgation. The revised FCM positive list will be enforceable from 1 June 2025, although existing materials may continue to be used until the end of the five-year transition period, which is 31 May 2025.

On 11 October 2024, Japan’s Ministry of Economy, Trade and Industry (METI), the Ministry of Health, Labour and Welfare (MHLW) and the Ministry of Environment (MOE) jointly released the 2025 e-application schedule for specific new chemical substances. METI published this application schedule along with detailed information on its portal. In addition, the schedule for the electronic submission of information for the manufacture and import of new chemical substances and low-volume new chemical substances, as well as the manufacture and import of intermediates, was released. 

New chemical substances that are manufactured or imported into the Japanese market in low quantities are subject to this notification as follows: 

• Low-volume new chemical substances: For the year 2025, the application schedule (notice) for the manufacture and import of low-volume new chemical substances, i.e. ≤ 10 t/y, has been released. 

• Small quantities of new chemical substances: The 2025 application schedule (notice) for the manufacture and import of small amounts of new chemical substances i.e. ≤ 1 t/y has been released. 

Annual Update of the Application Schedule 

Every year in October, the Ministry revises the application schedule for e-submission. METI has already updated the new chemical application schedule for the year 2024 on 13 October 2023. The application schedule for the year 2026 is expected to be released in October 2025, but METI has not yet made it official.

On 19 September 2024, Japan’s Ministry of Health, Labour and Welfare (MHLW), Ministry of Economy, Trade and Industry (METI) and Ministry of the Environment (MoE) jointly notified the World Trade Organization (WTO) of a draft proposal to designate three chemicals as Class I Specified Chemical Substances. The three chemicals which were mentioned in the draft are Methoxychlor, Dechlorane Plus and UV-328. 

The Act on the Regulation of Manufacture and Evaluation of Chemical Substances regulates these Class I Specified Chemical Substances, which will be amended to add these three chemicals to the list of Class I Specified Chemical Substances. 

The three Class I Specified Chemical Substances are as follows. 

Background 

Earlier in May 2023, at the 11th Conference of the Parties to the Stockholm Convention on Persistent Organic Pollutants (POPs) these three chemicals were added to Annex A of the Convention which can be accessed here. In reply to this, a consultation regarding these designations was held by the three ministries in December 2023. 

Class I Specified Chemical Substances 

Class I Specified Chemical Substances are defined under Japan's Chemical Substances Control Law (CSCL) as substances that have been determined to be persistent, extremely bioaccumulative, or potentially hazardous to the environment and human health over an extended period of time. Manufacturers and importers are required to obtain a permit before manufacturing or importing certain compounds. 

Exemptions 

This order includes some exemptions for the use of Dechlorane Plus in certain applications. 

Comment Period and Enforcement Dates 

Stakeholders are invited to comment on this draft proposal until 18 November 2024. The enforcement order will be adopted in December 2024 and come into force in February 2025. In addition, the importation of products containing Dechlorane Plus and UV-328 (as listed in the table below) will be banned from June 2025.
