Compliance varies significantly by region. For the US market, ensure products do not violate state-specific restrictions (e.g., wrist-braced slingshots are restricted in some areas). For the EU, products must comply with the General Product Safety Directive (GPSD). If the slingshot is marketed as a toy, it must pass EN71 or ASTM F963 testing. However, most professional slingshots are classified as sporting goods, requiring clear age-restriction labeling (18+) and comprehensive safety warning manuals.
