Import Tips

• Verify engine power rating with manufacturer specs and include propulsion end-use certification for vehicles of Chapter 87; common pitfall is misclassifying as stationary garden equipment

• Ensure cylinder capacity documentation matches 250-1000cc range

• Obtain EPA/CARB emissions labels for US compliance
