To ensure market access and consumer safety, verify that the manufacturer adheres to OEKO-TEX Standard 100, which guarantees the textiles are free from harmful chemicals. For the US market, compliance with CPSIA (Consumer Product Safety Improvement Act) is mandatory, especially regarding lead content in zippers and buttons. For the EU, ensure the products meet REACH regulations. If you are positioning your brand as sustainable, look for GOTS (Global Organic Textile Standard) or GRS (Global Recycled Standard) certifications.
