Import Tips
• Include fatigue test data and crystal grower compatibility certificates in shipment documentation
• Mark packages with 'Semiconductor Grade - Statistical Note 3' to expedite customs processing
• Avoid reclassification by providing OEM specifications linking to wafer manufacturing equipment
