Korea Chemical Names Update

South Korea has launched a public consultation on a major revision of names for existing chemical substances, aimed at improving clarity, consistency, and alignment with international naming standards under K-REACH.

Public Comment Deadline was: 16 April 2026

Key Regulatory Developments

The National Institute of Chemical Safety (NICS) is proposing to revise the naming of numerous existing chemical substances listed in Korea’s chemical inventory.

Key elements include:

• Standardization of chemical names and identifiers
• Alignment with international nomenclature systems (e.g., IUPAC-based naming)
• Correction of inconsistencies and ambiguities in existing listings
• Improved linkage between substance names, CAS numbers, and regulatory data

This revision is intended to enhance regulatory transparency and reduce confusion in compliance processes.

Regulatory Context

The update falls under the framework of K-REACH, which requires accurate identification of chemical substances for:

• Registration and notification
• Hazard classification and labeling
• Risk assessment and regulatory control
• Clear substance identification is critical to ensure proper compliance and enforcement.

Scope & Key Changes

• Applies to existing chemical substances listed in Korea’s inventory (KECI)
• Focuses on name corrections and standardization, not new restrictions

May affect:

• Substance identity records
• SDS and labeling information
• Registration dossiers

The revision does not introduce new substances but ensures data accuracy and harmonization.

• Thresholds & Compliance Impact
• No tonnage thresholds involved
• Changes are administrative but legally relevant

Companies must ensure that:

• Substance names match updated official listings
• Documentation reflects revised nomenclature
• Even though not restrictive, the update has direct compliance implications.

Who is Affected ?

• Chemical manufacturers and importers in South Korea
• Only Representatives (ORs)
• Downstream users and distributors
• Global exporters supplying chemicals to Korea

Any company referencing Korean chemical inventory data must align with the revised names.

Compliance & Operational Implications

Companies should prepare to:

• Review affected substances in their portfolios
• Update Safety Data Sheets (SDS) and labels
• Align internal databases and compliance systems
• Ensure consistency across global regulatory submissions
• Failure to update documentation may lead to regulatory inconsistencies or compliance risks.

Timeline & Next Steps

• Consultation Open: March 2026
• Deadline for Comments: 16 April 2026
• Post-Consultation: Finalization and official publication of revised names
• Implementation: Expected shortly after final adoption

South Korea’s proposed revision of chemical substance names represents a significant step toward improving regulatory clarity and international harmonization under K-REACH. While primarily administrative, the changes require careful attention from companies to ensure accurate documentation and continued compliance in the Korean market.
