Taiwan’s chemical registration system (Taiwan REACH) began in December 2014. The administrative costs for dossier review, registration extension and modification, certificate issuance, CBI protection, etc. were previously stipulated in the Standard on Toxic Chemical Substances Handling Application Fee and Chemical Registration Fee. On April 7, 2021, Taiwan EPA published the revised standard and renamed it as the Standard for Fee Charged for Toxic and Concerned Chemical Substances Control Act. It took effect on April 9, 2021.
