Import Tips
• Verify bearing specifications match semiconductor equipment use to avoid reclassification under machinery headings
• Provide detailed technical datasheets and end-use certificates for Customs to confirm 'other' ball bearing status
• Check for anti-dumping duties on bearings from specific countries like China or Europe
