Safety is the paramount concern for infant accessories. You must ensure all materials are BPA-free, lead-free, and phthalate-free. For the U.S. market, products must comply with CPSIA (Consumer Product Safety Improvement Act) standards, while the EU market requires EN71-3 certification. Specifically, look for fully lined clips (ribbon-wrapped) to prevent the metal from scratching the baby's scalp and ensure that all decorative elements are attached with non-toxic, high-strength adhesive to prevent choking hazards.
