The Act on Registration and Evaluation, etc of Chemical Substances (known as K-REACH) aims to protect public health and the environment. This is achieved by four procedures, namely notification or registration, evaluation, authorization, and restriction of chemicals. K-REACH has been enforced since January 1, 2015 and the recent amendment has come into force on August 7, 2025.
Relevant documents are available at Menu > Regulatory Regions > South Korea > Compliance Library.
Under K-REACH, any person who intends to manufacture or import a new chemical substance or at least one ton per year of an existing chemical substance shall register the chemical substance ("registration") according to the following requirement:
Foreign manufacturers who export chemical substances to South Korea may appoint a Korea-based Only Representative to submit pre-registration or registrations.
Besides, producers and importers of products containing priority control substances need to register their products to the Ministry of Environment before placing them in Korea.

(1) ‘New Substance’ is a substance that is not listed on Korean Existing Chemicals List (KECL)
(2) ‘Product’ is a mixture, or an article used by consumers or a component of the mixture or the article that may expose consumers to chemical substances
Ony Representative (OR) is an intermediary, and is mandatory for companies based outside of South Korea wishing to register the substance they export to South Korea. Foreign companies may appoint Korea-based ORs to fulfil relevant obligations under K-REACH.
K-REACH pre-registration start from 1 Jan 2019 and end on 30 June 2019. It is required all >=1t/y existing chemical substances manufactured in or imported to South Korea. Only those pre-registered existing substances can benefit from registration grace periods, during which one can manufacture or import those pre-registered substances without full registrations.
1. Scope
K-REACH pre-registration is only required for >=1t/y existing chemical substances. New chemical substances do not require pre-registration and they must be registered before manufacture or import.
2. Object
A Korean manufacturer or importer of >=1t/y existing substances shall submit pre-notifications to the Ministry of Environment. This should be done between 1 Jan 2019 and 30 Jun 2019. Foreign manufacturers or formulators can appoint Korea-based Only Representatives (OR) to submit pre-registrations. Downstream users and foreign traders cannot submit pre-registrations.
Late pre-registration is possible for existing substances exceeding 1t/y for the first time after 30 June 2019. At least, 12 months before the relevant grace period deadline for registration.
3. Information requirements
Required information for K-REACH pre-registration is as follows:
It should be noted that one applicant shall update their pre-registrations within one month if there are changes with:
According to the article 10 of amended K-REACH regulation, any person who intends to manufacture or import a new chemical substance or at least one ton per year of an existing chemical substance shall register the chemical substance before he or she manufactures or imports the substance.
1. Scope
K-REACH registration is required for >=1t/y existing chemical substance and >=1t/y new chemical substances. To find out if a substance is an existing substance or not, you shall search Korea Existing Chemicals List first.
| Substance type | Obligations |
New substance < 1t/y |
|
New substance >= 1t/y |
|
Existing substance >= 1t/y |
|
2. Object
Only Korean manufacturers and importer are obligated to register chemical substances under K-REACH. Foreign manufacturers may appoint Korea-based Only Representatives to submit chemical registrations on their behalf.

South Korea implemented the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in 2013. Currently, the fourth revised edition of the GHS (GHS4) is applied in South Korea under different regulations including the Korea Occupational Safety and Health Act (K-OSHA) and the Standards for Classification and Labeling of Chemicals and Safety Data Sheets. K-OSHA, last updated in 2024, imposes a duty on manufacturers and importers of chemicals supplied to Korea to correctly classify the chemical according to GHS4, label hazardous chemicals in the workplace, and provide Material Safety Data Sheets (MSDSs). Different authorities implement GHS in South Korea are summarised below:
| Authority | Regulations | Standards | Applicable to |
| MoEL | Occupational Safety & Health Act (OSHA)
| Standard for Classification & Labelling of Chemical Substances & MSDS (Public Notice of MoEL No. 2023-9) | Chemicals as per GHS hazard classification standards
|
| MoE | Chemicals Control Act (CCA) & Chemical Substance Registration & Evaluation Act (Korean-REACH) | Regulation on Classification & Labelling of Chemical Substances (National Institute of Environmental Sciences Manuscript No. 2024-35) | Designated hazardous chemicals |
| NEMA | Dangerous Goods Safety Control Act (Previously Fire Service Act) | Standards for classification & labelling of dangerous goods (Fire Agency Notice No. 2022-78) | Chemicals with flammability/ignitability |
The following GHS hazard categories are exempt from classification under K-OSHA:
The following GHS hazard categories are not mandatory to separate categories under K-OSHA:
Like many other countries, South Korea also has its own GHS labeling requirements. The requirements are set by the Standards for Classification and Labeling of Chemicals and Safety Data Sheets. Any classified chemical is correctly labelled if the label includes the following in Korean:
The label must comply with the following size requirements:
| Volume of the container or package | Label size |
| Volume ≥ 500 l | Over 450 cm2 |
| 200 l ≤ Volume < 500 l | Over 300 cm2 |
| 50 l ≤ Volume < 200 l | Over 180 cm2 |
| 5 l ≤ Volume <50 l | Over 90 cm2 |
| Volume < 5 l | Over 5% of total surface area of the container or package, excluding the top and bottom areas |
The pictogram in the label must comply with the following size requirements
The following requirements should also be considered:
Since 16 January 2021, Korean authorities require that manufacturers, importers, or Only Representatives (ORs) appointed by non-Korean manufacturers submit a Material Safety Data Sheet (MSDS) before manufacturing or importing chemical substances. The MSDS must be submitted in Korean Language and follow the fourth revision of UN GHS. If a chemical substance has been placed in the Korean market and an MSDS has been prepared before 16 January 2021, there are grace periods given to submit MSDSs based on the quantity of the substances, as follows:

The Consumer Chemical Products and Biocide Safety Management Law (known as K-BPR) concerns the placing on the market and use of hazardous consumer chemical and biocidal products, which aims to protect public health and environment from these chemicals and products. This is achieved by assessment or notification of consumer chemical products’ risk, authorization of biocidal chemical substances and products and determination of biocidal chemical used products. K-BPR was taken into force on January 1, 2019, and its recent amendment was promulgated on March 24, and May 26, 2020. Its enforcement will start on January 1, 2021.
1. Consumer chemical product
Ministry of Environment (MoE) designated consumer chemical products that have a potential to expose hazardous chemicals to human and environments while its use at the home, office, and public facilities (“consumer chemical product subject to safety confirmation”). The consumer chemical products are categorized into two, of which requires either approval or notification.
1) Notification of consumer chemical products subject to safety confirmation
Any person who intends to manufacture or import a consumer chemical product that is subject to notification needs a product safety confirmation from concerned research institutes and notifies the confirmation results to Korea Environmental Industry & Technology Institute (KEITI) no later than 30 days since its confirmation.
2) Approval of consumer chemical products subject to safety confirmation
Any person who intends to manufacture or import a consumer chemical product that is subject to approval shall gain approval from MoE. It includes sterilizing materials such as anti-bacterial disinfectant for humidifiers, for preventing infectious diseases and other disinfection purposes, as well as insecticides, rodenticides, and hygiene repellents.
2. Biocides (Biocidal substance, biocidal product, biocidal treated product)
Any person who intends to manufacture or import biocides shall gain approval from MoE. Biocides under K-BPR refer to biocidal substances, biocidal products, biocidal treated products.
1) Biocidal substance
Biocidal substance refers to the chemical, natural material and microorganism to remove or control harmful organisms like pests and bacteria and make them harmless.
* Existing Biocidal Substance
Existing Biocidal Substance refers to a biocidal active substance included in biocidal products, which has placed on the market before December 31, 2018. By December 31, 2019, the list of 741 existing biocidal substances has been confirmed and varying substances have different grace periods.
* Biocidal substance other than the Existing Biocidal Substance
Any person who intends to manufacture and import biocidal substances requires approval from MoE. It applies to all biocidal substances except designated substances that have fewer risks, substances are used for research purposes and are subject to other laws.
2) Biocidal product
Biocidal product is defined as an article mainly used to remove harmful organisms, which is,
Any person who intends to manufacture and import biocidal products requires approval from MoE. Once a product is approved to be manufactured or imported, safety labelling for products concerned shall be stated.

(1) ‘Consumer chemical product’ is defined as an article that has a potential of chemical exposure to human and environment while its use at the home, office, and public facilities etc.
(2) 'Biocidal substance’ refers to a chemical, natural material and microorganism to remove or control harmful organisms like pests and bacteria and make them harmless
(3) ‘Biocidal product’ is an article mainly used to remove harmful organisms, which is
(4) ‘Biocidal treated product’ refers to a product that uses biocidal products during the production process, but its main purpose is not to remove harmful organisms
As per the recent amendment of K-BPR on March 24, 2020, the concept of Only Representative (OR) is included in the law, which will take into force on January 1, 2021. OR is an intermediary appointed by a foreign manufacturer based outside of South Korea to get an approval of consumer chemical products, biocidal substances, and biocidal products so that such chemicals and products can be imported in South Korea.
During the grace periods, any person who intends to manufacture or import biocides can continue to manufacture and import the biocides without approval from MoE once he or she submits an Existing Biocidal Substance notification to MoE. By December 31, 2020, for those companies who had reported their Existing Biocidal Substances, an approval plan (simplified version of approval application) shall be submitted in National Institute of Environmental Research (NIER).


Biocides approval process begins with submitting approval application. Once the authority initiates the assessment, a notice informing approval assessment initiated will be sent to the applicant. In six months from the date of the notice, approval assessemnt result will come out and might require more information from the applicant. After going through committee deliberation, the approval application is finally approved and will be notified to the applicant. This process is described in the picture below.

For biocides use approval, then necessary documents are as follows.
1. Biocidal substance
An approval application form that includes applicant and biocides information (e.g. product name, material type etc.)
2. Biocidal product
An approval application form that includes applicant and biocides information (e.g. product name, material type etc.)
Each biocides use approval has expiration period.
