Compliance is the most critical factor for cross-border toy products. For the US market, products must pass ASTM F963 and CPSIA testing, requiring a Children’s Product Certificate (CPC). For the EU, the EN71 series (Parts 1, 2, and 3) and CE Marking are mandatory to ensure mechanical safety and the absence of toxic chemicals. Additionally, ensure all materials meet flame retardancy standards and that the 'bouquet' wrapping materials (paper or plastic) comply with regional packaging waste directives.
