Possibility of exemption from registration

Similar to EU REACH, Korea K-REACH stipulates that certain uses or products (such as drugs, food, etc.) do not require K-REACH registration.

When a chemical substance has multiple uses, it is only necessary to register the quantity for the purpose of registration, and the quantity for the purpose of exemption registration does not need to be registered.
