Import Tips
• Provide material test certificates (MTC) confirming alloy composition and heat treatment suitable for wind turbine fatigue loads
• Label clearly as 'wind turbine gearbox part' to distinguish from automotive or industrial shafts
• Ensure shaft tolerances meet ISO 6336 standards for gearing to prevent CBP challenges
