Fashion accessories often fall under strict chemical safety regulations. For the EU market, products must be REACH compliant, specifically testing for lead, cadmium, and nickel release to prevent skin allergies. For the US market, compliance with CPSIA is crucial if the product could be perceived as appealing to children, and California Proposition 65 warnings may be required if certain phthalates or heavy metals are present. Always request third-party lab reports (SGS, Intertek, or TUV) from the supplier.
