Import Tips
• Verify material composition (e.g
• bronze alloy specs) with mill test certificates to confirm classification as plain shaft bearing
• Include end-use documentation proving use in semiconductor processing to avoid reclassification as machinery parts
• Check for tolerances and certifications like ISO 9001, as precision affects duty and compliance
