Import Tips
• Verify RoHS compliance and obtain supplier datasheets confirming it's a microcontroller IC for customs classification
• Include ECCN export control numbers if applicable for dual-use semiconductors; avoid misclassification as memory-only
• Package in anti-static materials to prevent damage; declare value per unit accurately for duty calculation
