On December 1, 2023, NIFDC introduced the Working Mechanism for Communication and Exchange of New Cosmetic Ingredients (Trial). This mechanism aims to facilitate the communication between registrants, notifiers, and the review department regarding technical matters pertaining to NCIs prior to the submission of registration or notification applications, as well as during the review process. General inquiries can be made in person, via email, or over the phone, while crucial technical matters can be addressed through meetings, driving consensus with the review department.
