Import Tips
• Verify gearbox ratios are manually selectable to avoid 8483.40.30 classification; provide engineering specs showing mechanical ratio selection
• Ensure origin certification for machinery parts duty preferences
• Common pitfall: misclassifying electronically controlled units as servomotors under 8501
