Compliance is critical for apparel. Ensure the products meet OEKO-TEX® Standard 100, which guarantees the absence of harmful substances like Azo dyes and formaldehyde. For the U.S. market, verify compliance with FTC labeling requirements (fiber content, country of origin, and care instructions). For the EU, ensure adherence to REACH regulations regarding chemical usage in textiles. Always request third-party lab test reports for colorfastness to perspiration and washing to avoid consumer complaints.
