Import Tips
• Verify the part is exclusively for steam turbines via manufacturer specs to avoid misclassification into general machinery parts
• Include detailed engineering drawings and end-use certificates in documentation to confirm HTS 8406.90.45 applicability
• Watch for common pitfalls like classifying assembled rotors as complete turbines under 8406.81, which changes duty rates
