On June 1, 2007, the European Union passed the Registration, Evaluation, Authorization and Restriction of Chemicals Regulation (hereinafter referred to as REACH Regulation) and formally implemented it on June 1, 2008. After the implementation of this regulation, chemicals entering the EU market will be managed uniformly. In response to the EU REACII Regulation, my country has formulated a series of chemical safety standards, which are equivalent to the relevant technical content of the EU REACH Regulation. This standard combines the relevant requirements of the EU REACH Regulation and my country's national standards to establish.
