Import Tips
• Verify certification that the part is specifically engineered for wind turbine gearboxes to avoid reclassification under general machinery parts
• Include detailed engineering drawings and wind turbine OEM specifications in documentation to prove end-use compliance
• Check for anti-dumping duties on steel castings from certain countries, common for gearbox housings
