Compliance is non-negotiable in the toy industry. Products must adhere to EN71 (Parts 1, 2, and 3) for the European market and ASTM F963 for the United States. Since these toys involve liquid solutions, the bubble fluid must be non-toxic, non-irritating to skin, and certified under MSDS (Material Safety Data Sheet). For electronic components, ensure the product carries the CE mark or FCC certification. Always verify that the plastic used is BPA-free and Phthalate-free to meet global health standards.
