On May 12, 2017, the Taiwan Environmental Protection Administration (EPA), Executive Yuan published a notice on the TCSCA Draft Amendment. The public comment period ended on July 11, 2017.

The main change of TCSCA lies with the introduction of “Chemical Substances of Concern” as a new category of regulated chemical substances. This category refers to chemical substances with the endocrine disruption characteristics, that are scientifically proven to cause environmental pollution, or are presumed to endanger human health based on domestic and international concern, and are officially announced by the central competent authority.

Below is a comparison between the drafted TCSCA amendment and the European Union Registration, Evaluation, Authorization and Restriction of Chemicals regulations (EU REACH).
