Import Tips
• Verify machine value with invoice; must be under $3,025 per unit to qualify for this subheading
• Provide technical specs confirming use for lapping semiconductor wafers or metal surfaces to avoid misclassification
• Include end-use statement for semiconductor manufacturing to support Chapter 84 classification over Chapter 90 testing apparatus
