1. Background  
At the 8th meeting of the Conference of the Parties to  the Stockholm Convention  on Persistent 
Organic Pollutants  in 201 7, “short -chained chlorinated paraffins (straight -chain chlorinated 
hydrocarbons with chain lengths ranging from C10 to C13 and a content of chlorine greater than 48 
per cent by weight) ” and “decabromodiphenyl ether ” came under its scope  for elimination . Based 
on the decisions , “short -chained chlorinated paraffins (straight -chain chlorinated hydrocarbons with 
chain lengths ranging from C10 to C13 and a content of chlorine greater than 48 per ce nt by 
weight) ” and “decabromodiphenyl ether ” will be  designated as Class I  Specified Chemical 
Substance s 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. In addition, the Act will expand its scope  of import restriction s to some  products in which  each 
material is used.  
Furthermore , the Act will additionally impose import restri ctions to some products which use 
PFOS or its salts. T hose materials  were  designated as Class I Specified Chemical S ubstances under 
the Act in 2010  and some of products  which use those materials have already restricted to import 
(refer to G/TBT/N/JPN/307 ). In this notification, the Act will expand the scope of import 
restrictions regarding those products .

2. Purpose  
 In order to prevent environmental pollution by the chemical substances that could pose a risk of 
impairing human health or of interfering with the population and/or growth of flora and fauna.  
 
3. The date of enforcement  
The amendment of t he order for enforcement  to prohibit impor t of the above  products , in which  
each chemical substance  is used , will enter into force in October  2018.
