Import Tips
• Verify material composition (e.g
• tungsten carbide grade) with supplier certificates to confirm classification under 9608.99.30.00
• Ensure balls are sized for pen tips (0.5-1.5mm); larger sizes may shift to general parts in 9608.99.80
• Include detailed technical specs in commercial invoice to avoid misclassification as mere metal balls under Chapter 81
