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”. A revision to the regulation will enter 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
  • 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

Our Regulatory Impact Assessments summarise the process, costs and timelines for registration, allowing you to make effective business decisions about your products.


Yordas Group has significant experience in submitting Registrations for a wide range of substances. Our regulatory consultants work very closely with our scientific experts throughout the Registration process on:

In-country Representation

To submit a registration under K-REACH, companies not located in South Korea must appoint a South Korean Only Representative. Yordas can provide an Only Representative to represent your company for the purpose of submitting notifications.

Yordas can support you at every stage, from classification of substances and mixtures, advising on labelling requirements (including font or hazard pictogram size, hazard and precautionary statement selection) and authoring Safety Data Sheets in the format and language required. We also can research and fill any gaps in your data.
