Import Tips
• Submit dyno test reports proving <746W power to prevent misclassification into higher-duty categories
• Declare as 'vehicle propulsion engine' with Chapter 87 compatibility; common error is generic descriptions triggering reviews
• Comply with noise/emission regs via labeling; watch for counterfeit markings leading to seizure
