Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If part of electrical apparatus connections
If integrated as components in electrical apparatus, may shift to 8536.
If intentionally doped variants
Doping changes it from chemically defined compound to prepared electronic material in 3818.
If other chemically defined mercury compounds
Subheading 2852.10 is mercury-specific; GaAs stays in 2853 as non-mercury inorganic.

Import Tips & Compliance
• Document crystal orientation (e.g
• (100) or (111)) and flatness specs (<1 micron) for accurate tariff classification
• Check BIS export licensing for GaAs wafers over certain sizes due to technology controls
