When sourcing children's apparel, compliance is non-negotiable. You must ensure products meet CPSIA (Consumer Product Safety Improvement Act) standards for the US market, which strictly limits lead and phthalate content in substrates and coatings. For the EU, adherence to EN 14682 is critical, as it regulates cords and drawstrings to prevent strangulation hazards. Additionally, look for OEKO-TEX® Standard 100 certification to guarantee the fabric is free from harmful substances, and GOTS (Global Organic Textile Standard) if you are marketing organic cotton products.
