1. Background  
At the 9th meeting of the Conference of the Parties to  the Stockholm Convention on Persistent 
Organic Pollutants  in 2019 , “dicofol ”, “perfluorooctanoic acid (PFOA), its salts ” and “PFOA -related 
compounds ” came under its scope  for elimination . Based on the decisions , “2,2,2- trichloro -1-(2-
chlorophenyl) -1-(4-chlorophenyl)ethanol  (also known as o,p’ -Dicofol) ” and “perfluorooctanoic acid 
(PFOA)  and/or its salts ” will be  designated as Class I  Specified Chemical Substances  under the Act 
on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. (hereinafter 
referred to as “ the Act ”) to prohibit their  manufacture, import and use.  Also , the Act will expand its 
scope  of import restriction s to some  products in which  each  material is used.   
In addition, this revision of the Act does not include the designat ion of PFOA -related compounds  as 
Class I Specified Chemical Substances.  
The other isomers of Dicofol, 2,2,2- trichloro -1,1-bis (4 -chlorophenyl) ethanol  (also known as p,p’ -
Dicofol) , has been already designated as Class I specified Chemical Substances under the Act in 2005.  
 (Refer to G/TBT/N/JPN/139 ).  
 
<Chemical Substances  to be designated as Class I  Specified Chemical Substances under the Act>

<Products to be banned to import, in which  “perfluorooctanoic acid (PFOA)  and/or its salts ” 
are used >

impairing human health or of interfering with the population and/or growth of flora and fauna.  
 
3. The expected date of enforcement  
Revision of the “ Order for Enforcement of the Act on the Evaluation of Chemical Substances and 
Regulation of Their Manufacture, etc. ” will enter  into force i n October 2021.
