Taiwan’s standard registration for 106 Priority Existing Chemicals (PECs) at or above one ton a year began on January 1, 2020. According to the Regulation of New and Existing Chemical Registration (hereafter referred to as the “Regulation”), the registration deadlines for PECs are differentiated based on the volume indicated when applying for phase 1 registration (pre-registration/late pre-registration) and the date on which the phase 1 registration code is obtained. Basically the standard registration for the PECs should be completed within 2 to 3 years.
