Japan defines long-chain PFCA-related substances under a ministerial order
The order specifies substances covered by the Class I Specified Chemical Substances designation and takes effect on 22 November 2026.
A joint ministerial order identifies the specific long-chain perfluorocarboxylic-acid-related substances covered by Japan's Class I Specified Chemical Substances framework. Its effective date is 22 November 2026.
Laboratories and businesses handling relevant raw materials or products should check whether their substances fall within the legal definition before that date. The official order, rather than a generic PFCA group label, determines scope.
