Import Tips
• Provide material composition certificates (e.g
• Si3N4 ceramics) to support hybrid classification and duty assessment
• Ensure invoices specify semiconductor end-use to prevent misclassification as general industrial bearings
• Avoid pitfalls by confirming ABEC/ISO precision class; ultra-precision may trigger different subheadings
