According to the KKDIK Regulation, isolated intermediates refer to substances manufactured to produce another substance in chemical processes and consumed or transformed during this process. These intermediates are isolated at certain stages in the production process and processed under strictly controlled conditions. Isolated intermediates are divided into two basic categories:
On-Site Isolated Intermediates: These are intermediates that are produced and used within the same facility. These substances are processed under strictly controlled conditions throughout their life cycle.
Transported Isolated Intermediates: These are intermediates that are transported to another facility after production and will be used there. They are also subject to strict control conditions during the transportation process and usage stages.
