Silicon Schottky Diode Wafer from Mexico
A large silicon wafer containing thousands of unmounted Schottky diode chips used in power rectification and high-frequency switching applications. These wafers are produced through semiconductor fabrication processes and diced into individual dice post-import. Classified under HTS 8541.10.0040 as unmounted chips, dice, and wafers specifically for diodes other than photosensitive or LED types.

Import Tips
• Verify wafer specifications including diameter, doping type, and diode characteristics match HTS 8541.10.0040 criteria for unmounted diode wafers
• Provide detailed manufacturing process documentation to customs to distinguish from mounted or assembled semiconductor devices
• Avoid common pitfalls by ensuring cleanroom packaging to prevent contamination claims during inspection
