For the US market, products must comply with CPSC (Consumer Product Safety Commission) regulations and be free from lead and phthalates. For the EU, CE marking and compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) are essential. Furthermore, ISO 9001 for quality management and ISO 13485 (if classified as medical grade) are highly recommended. Always request third-party lab test reports (e.g., SGS or Intertek) for skin irritation and sensitization to ensure infant safety.
