Overview of K-REACH

In accordance with the requirements of the amended K-REACH, manufacturers/importers that manufactured or imported at least one ton per year of an existing substance between 2016 and 2018, shall submit application for pre-registration between 1 Jan. 2019 and 30 Jun. 2019. Enterprises that have completed the pre-registration can enjoy a corresponding registration grace period based on the tonnage band as well as the hazards of substances.

Up to 30 Jun. 2021, a total of 17,153 substances have submitted the applications for pre-registration under K-REACH, of which 78 are CMR substances, and 1,837 are exceeding 1000t/a. Up to the end of 2021, 1,906 substances shall complete full registration. 

Grace Period

Under the amended K-REACH, grace period varies depending on the pre-registered tonnage and the hazard characteristics. Details are as follows:


It is worth mentioning that the grace period for CMR substances exceeding 1t/a and existing substances exceeding 1000t/a will be closed on 31 Dec. 2021. Related enterprise shall complete the full registration for these substances in advance or they will not be able to trade with South Korea from 1 Jan. 2022.

Currently, there are a total of 364 CMR substances. Enterprises may check whether their substances are CMR substances through CIRS‘s ChemRadar.


Enterprises that intend to manufacture or import the following substances are obligated to complete K-REACH registration:

  • At least 0.1 ton/y of a new chemical substance;
  • Existing substances manufactured, imported or sold more than 1 ton per year;

New substances manufactured or imported at least 0.1 ton/y shall be registered prior to manufacturing or importation. A grace period (given to pre-registered substances) will be granted to existing substances to be manufactured/ imported at least 1 ton/y.

Similar to EU REACH, foreign manufacturers exporting chemical substances or products containing hazardous chemical substance into South Korea may appoint an Only Representative to fulfill relevant obligations under K-REACH.

Definition of New Substances

A new substance is defined as a substance that is not on Korea Existing Chemicals List (KECL), which includes:

  • Chemical substances which were placed on Korean market before Feb. 2, 1991, and notified by the Ministry of Environment on Dec. 23, 1996; and
  • Chemical substances which have undergone the examination of toxicity under the former provisions or the provisions of this Act after February 2, 1991 and were announced by the Minister of Environment.

Registration Fee

The LOA fee for a substance with a lead registrant and consortium formed is as follows:

LR/Consortium Management Organisation


OR (If needed)

CICO Management Fee+ Data Fee +CSR Fee

Administrative Fee (about 200 USD)

OR Service Fee

If the lead registration of a substance has not yet been elected, it is suggested that related enterprises complete the registration as a LR. Main expense is as follows:

Consortium Management Organisation


Consortium Management Fee + Data Fee + CSR Fee

Administrative Fee (about 200 USD)

It is undeniable that the data fee and the management fee for a LR are quite high. But when there are other members join the joint submission, LR is able to sell LOA to the co-registrant to reduce cost.

The registration fee will vary depending on different substances.   

Simplified Process under K-REACH

If the substance is not for consumer use or the substance is classified as low hazard or no hazard, a simplified registration will be available and the data fee can be partially exempted. However, if the substance is found to have health hazards or aquatic hazards, then related enterprises may need to supplement data.

Hazard Classification (Acute Toxicity)

The test data and the registration dossier shall be submitted together

Before Simplification

After Simplification

Substances with high risks

(Substances that do not fulfill the requirements of substances with low or medium risks)

Up to 47 items

  • 13 Physicochemical data
  • 15 Health toxicological data
  • 19 Environmental and eco-toxicological data

Remain unchanged

Substances with low risks


Up to 33 items

  • 13 physicochemical data
  • 15 health toxicological data -5 environmental and eco-toxicological data

Substances with no hazard classification or pictogram

15 items

Recent Updates

Recently, the scope of existing substances in South Korea has also been revised. Details are as follows:

  • Hydrates or anhydrates of existing substances are all considered as existing substances;
  • Reaction products composed of two or more components, and each component is an existing substance (these components are difficult to separate by technical means, and the reaction product itself is distributed or used in the market). Under this circumstance, the reaction products are also considered as existing substances; and
  • If an existing substance has two or more configurations, then each specific configuration is regarded as an existing substance;
  • Substances listed in Annex 3, see detailed information of the substances

CIRS warmly reminds that related enterprises may re-check whether their substances are existing substances. Besides, as the registration system has not been updated, it’s still not possible to submit pre-registration for the above four types of substances. But as long as the registration system is updated, related enterprises can submit pre-registrations and join CICO for joint registration.
