Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If undoped or raw GaAs material
Undoped gallium arsenide falls under carbides, nitrides, etc., without specific electronic doping.
If processed into finished semiconductor devices
Once fabricated into LEDs or transistors, it shifts from doped wafer to photosensitive semiconductor device.
If other doped chemical compounds like silicon wafers
Silicon-based doped wafers use the residual subheading, distinguishing from specific GaAs classification.

Import Tips & Compliance
• Verify doping specifications and purity levels (e.g
• n-type or p-type) in documentation to confirm classification under 3818.00.0010
• Include certificates of analysis from manufacturer detailing GaAs composition and dopant concentration to avoid reclassification
• Ensure proper ESD-safe packaging and labeling as hazardous materials if applicable due to arsenic content
