South Korea GHS Compliance: 2026 Updates for K-REACH, SDSs and Labels

Free Webinar | October 21, 2026 | 10:00–11:00 AM BST

South Korea’s chemical hazard communication requirements are changing. For companies supplying chemicals to the Korean market, understanding the latest K-REACH, GHS, SDS, and labeling requirements is essential for maintaining compliance.

Join CIRS and EPY for a practical 60-minute webinar covering the key regulatory changes affecting chemical companies in South Korea in 2026.

South Korea has introduced important changes to its chemical hazard communication framework.

The 2024 amendments to K-REACH, which took effect on August 7, 2025, redefined the categories of toxic substances and introduced the concept of “substances with unconfirmed hazards.”

At the same time, MoEL Notice No. 2025-50 revised the Standards for Classification, Labelling and Safety Data Sheets.

From July 1, 2026, SDSs placed on the Korean market must follow the revised format.

For manufacturers, importers and distributors, these changes mean that existing chemical compliance processes, SDSs and labels may need to be reviewed and updated.

This webinar brings together CIRS and EPY expertise to explain how the different parts of South Korea’s chemical regulatory framework fit together — and what companies need to consider for their products.

The session will provide a practical overview of South Korea’s current requirements for chemical hazard communication, including:

• The latest developments under K-REACH;

• The relationship between K-REACH, the Chemicals Control Act (CCA), and the Occupational Safety and Health Act (K-OSHA);

• The 2024 K-REACH amendments and newly defined substance categories;

• The revised Korean GHS classification and labeling requirements;

• The new SDS requirements applicable from July 1, 2026;

• Key information required in a compliant Korean SDS;

• South Korean GHS label requirements;

• The obligations of manufacturers, importers, and distributors; and

• Practical considerations for maintaining chemical compliance in the South Korean market.

The webinar will conclude with a live Q&A, giving attendees an opportunity to raise their specific questions with the speakers.

By the end of the session, you will have a clearer understanding of:

01 — The Regulatory Framework – How K-REACH, the CCA, and K-OSHA interact and what the latest changes mean for chemical compliance.

02 — Korean SDS Requirements – What companies need to know about the revised SDS requirements now applicable to products placed on the Korean market.

03 — GHS Labels – The key elements of compliant GHS classification and labeling for South Korea.

04 — Supply Chain Responsibilities – The specific compliance obligations of manufacturers, importers, and distributors.

05 — Practical Next Steps – What to review within your existing SDS, labeling, and chemical compliance processes.

This webinar is recommended for professionals responsible for chemical compliance and hazard communication, including:

• EHS managers and chemical safety professionals;

• Regulatory affairs professionals;

• R&D professionals involved in SDS preparation;

• Professionals responsible for chemical classification and labeling;

• Manufacturers, importers, and distributors supplying the South Korean market; and

• Anyone responsible for chemical regulatory compliance at company level.

The session is suitable for beginner-to-intermediate level.

Whether you are new to chemical safety communication or already manage a complex SDS portfolio, the webinar will provide practical guidance on the current South Korean requirements.
