Japan’s National Institute of Technology and Evaluation (NITE) announced significant updates to chemical inventories and risk information platforms, including NITE-CHRIP, under the Chemical Substances Control Law (CSCL).
The update revises substance listings, classifications, and regulatory obligations for chemical management in Japan, impacting manufacturers, importers, and distributors.
Key Updates
The inventory updates affect the following CSCL categories:
• Class I Specified Chemical Substances
• Priority Assessment Chemical Substances
• Newly Announced Chemical Substances (notified after 1 April 2011)
• Existing Chemical Substances
• Type II Monitoring Chemical Substances (pre-amendment)
Major changes include:
• Revised combinations of MITI numbers and CAS Registry Numbers (CAS RNs)
• Updates to newly announced chemical substances lists (public notice issued 31 July 2025)
• Amendments to chemical-notification requirements, monitoring categories, and exemptions
Industry Impact
Companies operating in Japan must:
• Check substance status against updated listings and classifications
• Review SDSs and labelling to align with new MITI/CAS numbers
• Assess compliance obligations if substances are reclassified or moved into Class I Specified Chemical Substances
• Monitor potential new risk assessment or notification requirements
Recommended Actions
• Download updated NITE-CHRIP and J-CHECK lists
• Map your chemical portfolio to revised MITI/CAS number combinations
• Evaluate registration, notification, or restriction obligations under CSCL
• Stay informed of updates from MHLW, METI, and MoE for implementation guidance
