Import Tips
• Verify wafer fabrication origin and purity specs via certificates of analysis to meet US semiconductor import standards
• Classify as unmounted only if not attached to any lead frame or substrate; packaged versions go to 8541.49.80
• Avoid misclassification as solar cells (8541.40) by confirming non-photovoltaic primary function
