Import Tips
• Provide detailed wafer specifications including diameter, doping levels, and resistivity to avoid misclassification as finished devices
• Include certificates of origin and material composition analysis to qualify for preferential tariff treatment under trade agreements
• Use anti-static, vacuum-sealed packaging to prevent damage; declare as 'unmounted wafers' explicitly on commercial invoice
