Baby footwear must adhere to strict chemical safety regulations because infants often put objects in their mouths. You must ensure products are BPA-free, lead-free, and phthalate-free. For the US market, compliance with CPSIA (Consumer Product Safety Improvement Act) is mandatory, while the EU market requires adherence to REACH regulations and EN 71-3 (Safety of Toys - Migration of certain elements). Always request OEKO-TEX Standard 100 certification to guarantee the textiles are free from harmful substances.
