When sourcing children's accessories, compliance is non-negotiable. You must ensure products meet CPSIA (Consumer Product Safety Improvement Act) standards for the US market, specifically regarding lead and phthalate content in plastics and zippers. For the EU, products must be REACH compliant. Additionally, ensure the bag features breakaway buckles or adjustable straps that do not pose a strangling hazard, and verify that all small decorative parts are securely attached to pass pull-tests and prevent choking risks.
