3818.00.00.10/2-Inch Doped Gallium Arsenide Wafer/China

2-Inch Doped Gallium Arsenide Wafer from China

A 2-inch diameter silicon wafer made from gallium arsenide (GaAs), doped with impurities like silicon or tellurium to enhance electrical conductivity for semiconductor applications. These wafers are polished to atomic-level flatness and used primarily in high-frequency electronics such as RF amplifiers and microwave devices. Classified under HTS 3818.00.0010 as chemical compounds doped for use in electronics in wafer form.

Import Tips

• 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
