The China New Chemical Substance Notification (China Reach), ever since it was launched, has been increasingly stringent on the testing data provided in the notification dossiers. It is frequently learned from many cases where the notifiers themselves confused with the certain data requirements according to the regulation, which has different levels towards different tonnage band of chemicals. For most notifiers, particularly those from outside China, the data collection has inevitably posed a big threat for continued manufacture or exportation. The problem is enlarged as the regulation is now taken more seriously by the authority and in essence caused by the lack of knowledge and tidings ever generated from the law enforcement body—CRC-MEP.
