KOSHA SDS submission

From January 16th 2021, for manufacturers and importers of hazardous chemicals based in Korea, they should submit the (M)SDS to MoEL before manufacturing or importing in accordance with current amended regulation. However, there is a transitional period for enterprises that previously prepared an SDS in accordance with Article 41(1) or (6) of the former K-OSHA Act. Those meeting the exception may submit the SDS to MoEL within specified deadlines based on manufacture or importation volumes as noted below:

  1. ≥ 1000tpa, before 16 Jan. 2022;
  2. 100-1000tpa, before 16 Jan. 2023;
  3. 10-100tpa, before 16 Jan. 2024;
  4. 1-10tpa, before 16 Jan. 2025;
  5. Less than 1tpa, before 16 Jan. 2026;

Manufacturers of hazardous chemicals based outside of South Korea may entrust an Only Representative (OR) based in Korea to submit the (M)SDS. (M)SDS shall be submitted through the official online IT system as shown below.


Fig 1. Submission Portal for MSDS

There are three options to submit (M)SDS with required materials:

  • Submit (M)SDS specifying 100% composition information (no matter the chemical ingredients are hazardous or non-hazardous);

  • Only submit (M)SDS specifying hazardous ingredients and a separate document providing information of other ingredients will also be submitted to MoEL together with the (M)SDS; and

  • Only submit (M)SDS specifying hazardous ingredients and a statement signed by foreign companies saying that all the non-disclosed ingredients are non-hazardous substances will also be submitted to MoEL along with the (M)SDS. This option is for imported products only.

For overseas manufactures, confirmation of chemical substance with LoC should also be submitted with (M)SDS together through online IT system.

After submitting the (M)SDS, related enterprises will be granted a serial number (AA00000-0000000000)

issued by MoEL. The number shall be written on the upper side of front page on the (M)SDS. If information in the (M)SDS is altered, then related enterprises must submit the updated (M)SDS to MoEL as soon as possible.

In principle, manufacturers of non-hazardous ingredients based outside of South Korea do not need to provide (M)SDS. They can appoint an OR based in South Korea to submit full ingredients list instead of the (M)SDS.

CBI Application

For hazardous chemicals exceeding the concentration limit, they must be reflected in the MSDS. However, manufacturers or importers are allowed for applying for CBI protection and to use an alternative name and/or alternative content for claiming trade secrets, but they need to get approval from MoE first. It is worth mentioning that enterprises cannot apply for CBI Protection for substances that are prohibited in South Korea, restricted substances, hazardous substances under control, CMR substances, etc.

Information required for CBI Protection Application includes:

  • MSDS

  • Applicant information;

  • Reason for CBI Protection;

  • Hazardous classification of the chemical products and the ingredients

  • Other documents

After the application for CBI Protection is approved, MoEL will issue an authorization number to the applicant. Applicant shall fill it in Part 3 of the (M)SDS. The validity period for CBI Protection is 5 years and enterprises may apply for extension of the validity period. Substances that have registered under K-REACH and passed the CBI assessment could not be used under CBI Protection under OSHA.
