Update: On 14 May 2025, Japan’s Consumer Affairs Agency (CAA) published a revised Q&A document on its portal to further clarify the provisions of a Positive List for Food Contact Materials (FCMs). The CAA has also added a comparison of the previous and newly updated Q&A provisions. 

Original Text: 

On 6 February 2025, Japan’s Consumer Affairs Agency (CAA) published a Q&A document on its portal to clarify the provisions of a Positive List for Food Contact Materials (FCMs). The Positive List is currently in a 5-year transition period ending on 1 June 2025. At the end of the transition period, only entries on the list will be permitted in food contact applications. New materials must undergo assessment before they can be added to the list. 

Key Insights from the Q&A Document  

The main focus of the Q&A document is the Positive List of FCMs, which is governed by the Food Sanitation Act and overseen by the CAA. In general, this Act provides the basis for establishing standards for FCMs.   

The Q&A document covers topics which include following:  

• Scope and definition of the Positive List.  

• Exclusions from the list. 

• Specific product categories. 

• Provisions for polymeric substances. 

• Limits for additives. 

• Implementation guideline. 

Guidance for Stakeholders  

The Food Sanitation Act regulates FCMs in Japan, and the CAA frequently updates its portal to reflect the most recent changes to the requirements and criteria for foods and food additives. The purpose of this Q&A document is to help suppliers, importers, and manufacturers in making efficient use of the Positive List. Adhering to the list helps to prevent non-compliance in the manufacture, import and supply of FCMs.

On 14 May 2025, Japan’s Consumer Affairs Agency (CAA) published safety review procedures for new substances used in food contact materials (FCMs) on the portal. These procedures primarily focus on newly approved and applied substances, which are usually listed publicly. A specific application procedure has also been developed to protect the intellectual property (IP) for businesses that are concerned that revealing the names and usage of substances could harm their ability to compete. 

Key insights from the Safety Procedures 

• Added provisions for the safety assessment of new substances and the re-assessment of already approved substances. 

• A specific procedure has been added to protect intellectual property (IP). 

Positive List for Food Contact Materials (FCM) 

The Positive List is currently in a five-year transitional phase that ends on 1 June 2025.  Only substances on the list will be allowed in food contact applications after the transition period.  New materials must be evaluated before being added to the list,.  

Guidance for Stakeholders   

In Japan, FCMs are governed by the Food Sanitation Act, and the CAA regularly updates its portal to reflect the latest modifications to standards and specifications for foods and food additives. This document aims to assist manufacturers, importers, and suppliers comply with the safety review process for new substances. Following the procedure helps to prevent non-compliance with FCM supply, import, and manufacturing regulations.

On 10 April 2025, Japan’s Ministry of Health, Labour, and Welfare (MHLW) updated its list of chemicals identified as strong mutagens on the Workplace Safety Site. With this update, MHLW added 17 newly notified chemicals. Mutagenic chemicals are regulated under the country’s Industrial Safety and Health Law (ISHL). With this addition, the list now contains a total of 1363 chemicals including 244 existing and 1119 newly notified mutagens. 

Understanding Strong Mutagens 

Mutagens are substances or agents that can cause genetic mutations, leading to changes in an organism’s DNA. Mutagenic effects can result in serious health problems such as cancer, birth defects, and genetic disorders. Strong mutagens are chemicals or physical agents with a high potential to cause significant genetic mutations. 

Previous Update in November 2023 

On 30 November 2023, the MHLW added 18 newly notified chemicals to the list of strong mutagens, bringing the total to 1346 at that time.

Background on PACS 

PACS are chemicals whose long-term effects on humans or the plants and animals that live in human habitats are not well understood. Therefore, in order to ensure compliance with METI laws and to encourage safety and responsibility in handling of chemicals, companies that manufacture or import these chemicals in quantities greater than 1 Tonne Per Annum (TPA) are required to file annual reports in order to protect living beings.     

Key Insights from the draft notice 

The draft notice lists the following chemicals that are proposed for addition to the PACS list because of their potential for causing long-term harm to humans or to plants and animals in the human environment is not fully understood: 

List of Newly Designated PACS 

The draft notice also lists the following chemicals whose PACS designation will be revoked due to: 

• Manufactured/imported volumes of less than 10 TPA reported for 3 consecutive years.  

• Indicated released volumes of less than 1 TPA to the environment. 

• Indication that they no longer pose a risk to living organisms.

• The handling of NPE and NPE-added water-based cleaning agents must comply with the measures outlined in the technical guidelines, as per Article 36, paragraph 1 of the Act. 

3. Labelling Requirements: 

• Containers and packaging of NPE and NPE-added water-based cleaning agents must display labels indicating compliance with the prescribed measures, in accordance with Article 37, paragraph 1 of the Act. 

Objective and Rationale: 

The primary objective of this designation is to protect animal and plant life, ensure public health, and protect the environment. This action reflects Japan's extensive efforts to protect the environment and ensure public health. 

Proposed Dates: 

• Date of Adoption: 1 October 2024 

• Date of Entry into Force: 1 April 2025
