Under China New Chemical Substance management mechanism, intermediates are divided into 2 categories: Seperated Intermediate and non-Seperatated Intermediate.

Intermediate refers to chemical substance which is generated from the previous chemical reaction step, and is consumed in a following chemical reaction process to produce another chemical substance or product, and shall not be present in produced chemical substance or product, unless as impurity.

 

Non-separated intermediates refer to those which are not moved from reaction vessels or reaction devices and also include those stored temporally in vessels after reaction for the next step of chemical reaction in the same plant.

 

 

NCS Registration requiremetn is not applicable to non-separated intermediates.
