Taiwan’s EPA updates guidelines for dossier registration

On 24 March 2023 Taiwan’s EPA published the updated Guidance for New and Existing Chemical Substance Phase One Registration and Guidance on Chemical Substances Hazard and Exposure Assessment. The updated guidelines aim to help companies to meet their dossier submission obligations under the Toxic and Chemical Substances of Concern Control Act (TCSCCA). 

Phase one registration is required for existing chemical substances manufactured in or imported to Taiwan with the quantity above 100 kg. Registrants that completed Phase One Registration will receive a Registration Number. Based on the issued date of this number, companies need to submit dossier in following date:

• Phase One Registration received before 31 December 2019 and the tonnage reaches 1 TPA, companies should complete dossier submission by 31 December 2024.
• Phase One Registration received after 1 January 2020 and the tonnage reaches 1 TPA in the same year, companies should complete dossier submission within 5 years.
