It was explained how the trade issue related to China's export of toys to the EU worked. In this paper, the risk factors for human health associated with unqualified products in terms of chemical hazards were investigated. The recall characteristics of China's toys by the EU "Safety Gate" in terms of recall frequency, notified countries, taken measures, and reasons for recall were analysed. Phthalate, boron, plumbum, and cadmium were discovered to be the primary causes. A risk assessment for boron in toys was done. It is advised to keep the boron element in slime under control; for children aged 3 to 6 years, the limit for boron migration in slime toys should be less than 704 mg/kg, and for children aged 7 to 12 years, it should be less than 1268 mg/kg.
