Import Tips
• Verify bearing dimensions and tolerances match semiconductor equipment specs; provide manufacturer certifications for precision classification
• Include end-use documentation proving use in wafer manufacturing to avoid reclassification as general machinery parts
• Ensure proper marking of material composition (e.g
• high-carbon chrome steel) to comply with Section XVI notes
