Act on the Registration and Evaluation of Chemical Substances (K-REACH)

The main industrial chemical regulation in South Korea is the Act on the Registration and Evaluation of Chemicals (AREC), commonly known as “K-REACH”. The revision to the Actwill entered into force on 1 January 2019.

K-REACH places significant obligations on manufacturers, importers, users and sellers of chemicals. Companies failing to comply can face large penalties, including penalty surcharges of up to 5% of sales and prison sentences of up to 5 years.

What are the obligations (from 1 January 2019)?

  • Pre-notification of existing substances manufactured or imported ≥1 tonne/year between 1 January and 30 June 2019. See: K-REACH pre-notification window - What you need to know
  • Registration of existing substances manufactured or imported ≥1 tonne/year (approximately 7000 substances) before specified registration deadlines
  • Registration of new substances prior to manufacture or import ≥0.1 t/y
  • Notification of new substances prior to manufacture or import <0.1 t/y
  • Where relevant, application for “Confirmation of Exemption from Registration”
  • Notification of priority control substances to the Ministry of Environment if manufactured/imported at >1 t/y and present in consumer products at > 0.1%.
  • Compliance with requirements for information provision in the supply chain
  • Compliance with authorisation and restriction requirements
