When sourcing adult products, material safety is the highest priority. You must ensure the products are made of medical-grade silicone or BPA-free ABS plastic, which are non-porous and body-safe. Suppliers should provide RoHS and REACH certifications to prove the absence of harmful chemicals. For the US market, compliance with FDA registration for Class II medical devices (if marketed as therapeutic) is essential, while the EU market requires CE marking and compliance with the WEEE directive for electronic waste.
