The amendment, passed on March 20, 2018, revises the Act on the Registration and Evaluation of Chemical Substances (K-REACH), which came into force in 2015. It requires business entities and government authorities to “prioritize vertebrate alternative testing when producing risk and hazard information for chemicals” (Articles 4 and 5), and specifies that “testing shall not be repeated for the same chemicals” (Article 16-2), according to Humane Society International (HSI). The amendment will enter into force in 2019.
