On 28 May 2025, Japan’s Consumer Affairs Agency (CAA) released updated guidelines relating to Food-Contact Materials (FCMs) under the Food Sanitation Act. The CAA published the guidelines on its official portal. This time, the CAA has revised the procedures for:  

1. Appendix 1 of the Standards for Food, Additives, etc for substances to be added or revised. 

2. The Monomer Notification, which lists allowable monomers and processing agents in food-contact materials.  

These updates replace the 2020 guidelines and aligns with the end of the Positive List (PL) transitional period on 31 May 2025. The new guidelines are mandatory from 1 June 2025.
