On November 17, 2023, the National Institute for Environmental Research (NIER) in South Korea published a partial amendment to the “Regulations on Classification and Labelling of Chemicals.” This amendment will take effect from the date of notification.
The key changes in this partial amendment include:
Revised Toxic Substances:
15 toxic substances, 2 restricted substances, and 6 substances requiring preparation for accidents have been updated.
The chemical names of these substances have been modified, and specific requirements regarding import declaration, business license, labeling of hazardous chemicals, and transitional measures have been established for the newly designated toxic substances.
Addition of New Chemicals:
A total of 55 new chemicals have been added to the list. The chemicals are listed in the table below.
