Import Tips
• Obtain material certificates confirming low-particle generation for cleanroom compatibility in semiconductor fabs
• Verify bearing precision class (e.g
• ABEC 7 or higher) matches equipment specs to avoid reclassification
• Include end-use statements proving semiconductor application to qualify for potential duty exemptions
