Substances subject to permission under K-REACH

Ellen Daliday of CIRS explains a key recent development in South Korea ’ s chemical regulations

On 15 October , two enforcement dates passed under South Korea ’ s Act on the Registration & Evaluation of Chemicals , which is also known as K-REACH . The first is for new rules on ‘ substances subject to permission ’, which will require companies to seek prior permission from the Ministry of Environment ( MoE ) if they want to import , manufacture or use any of the substances . The second is the enactment of Article 24 of the enforcement rules for K-REACH . This will mean that registrants have the opportunity to talk to the National Institute of Environmental Research ( NIER ) about the results of its hazard evaluations .

Substances subject to permission
Under the Chemical Substances Control Act ( CCA ) ‘ substances subject to permission ’ are defined as ‘ chemicals likely to be harmful ’. The term is not new and has been in place since the enactment of the CCA in 2015 . However , it was not until 29 July 2022 that the MoE defined its selection criteria for these substances . According to the newly added Article ( 34 ( 2 )) of K-REACH , the MoE will consider multiple criteria when selecting substances to designate as ‘ subject to permission ’ ( Figure 1 ). The ministry has yet to designate any substances , but it will need to collect a wide range of public opinions when it does . This will include information on the hazardousness of the substances , as well as understanding the alternative substances and technologies available , before it officially notifies the substances .

Companies would be required to submit risk analysis and information on the proposed use and analysis of alternative substances in order to gain permission to manufacture , import , or use a permitted substance . If no alternatives are available , the MoE will permit companies to continue using these substances for a specific period under strict management controls .
Pilot project
Between 30 December 2021 and 20 January 2022 the MoE conducted a pilot project , which focused on the following ten substances :
• Benzo [ def ] chrysene ( benzo [ a ] pyrene ) ( Cas 50-32-8 )
• Benz [ a ] anthracene ( Cas 56-55-3 )
• Formamide ( Cas 75-12-7 )
• p- ( 1,1-dimethylpropyl ) phenol ( Cas 80-46-6 )
• Tris ( 2-chloroethyl ) phosphate ( Cas 115-96-8 )
• Sodium peroxoborate ( Cas 7632-04-4 )
Carcinogenic , mutagenic , or toxic for reproduction ( CMR ) substances
Endocrine disrupting chemicals ( EDCs ) .
Persistent bioaccumulative ( PB ) and very Persistent very Bioaccumulative ( vPvB ) substances .
Respiratory sensitizers .
Specific target organ toxicity ( slot ) substances .
Risk posed due to the volume of the substance used .
Rubstances covered by domestic and international regulations .
• Perboric acid , sodium salt ( Cas 7632-04-4 )
• Sodium tetraborate , pentahydrate ( Cas 11138-47-9 )
• 2-ethylhexyl 10-ethyl-4,4- dioctyl-7-oxo-8-oxa-3,5-dithia-4- stannatetradecanoate ( Cas 15571-58-1 )
• Trixylyl phosphate ( Cas 25155-23-1 ). The MoE selected companies to participate in the pilot project . They were provided with a review summary for each substance , which provided the rationale for the ministry ’ s selection of the substance , including hazard information , a review of existing regulations overseas and current distribution domestically . The companies were asked to provide feedback on the designation process including various questions and information on : grace periods ( Figure 2 ); exemption use ; distribution volumes ; alternative substances ; and suitability of questionnaire questions . In South Korea , the government often trials projects prior to making them
