Import Tips
• Verify turbine output does not exceed 40 MW with manufacturer specs for correct subheading classification
• Include detailed technical documentation proving semiconductor end-use to avoid reclassification as general machinery
• Ensure compliance with energy efficiency standards and obtain necessary industrial import permits
