On December 31, 2024, the Korean Environment Corporation (K-ECO) notified an updated template of the Letter of Confirmation (LoC) for chemical substance verification.  

Key Contents  

• Based on Article 2 of the Enforcement Rule of K-CCA (Korea Chemical Control Act), manufacturers and importers must submit either a Chemical Substance Composition Statement or the LoC to the Ministry of Environment (MoE), for chemical substance verification.  

• According to the K-CCA amendment, the previous template of the LoC can only be used till August 6, 2025. After this date, only the new template will be accepted.

• As of January 1, 2025, the authority responsible for chemical substance verification has changed from the Korea Chemical Management Association (KMCA) to the Korea Environment Corporation (K-ECO). 

The new LoC template can be downloaded from the official website of Chemical Substance Information Management System (k-reach.me.go.kr).
