Compliance is critical to avoid customs seizures. For the US market, vehicles must meet EPA (Environmental Protection Agency) or CARB (California Air Resources Board) emission standards and comply with ANSI/SVIA 1-2017 safety requirements. For the European market, CE marking and e-Mark certification (for road-legal versions) are essential. Ensure the supplier provides a Certificate of Conformity (CoC) and that all safety components like roll cages, four-point seat belts, and kill switches meet international protective standards.
