Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used solely as measuring/testing equipment components
If imported as part of optical or precision measuring instruments, may fall under 9031.
If cut and doped for electronic applications
Doped wafers for electronics explicitly go to 3818 per notes.
If complex salts or other metal compounds
Double salts or peroxysalts of metals classify in 2842, but pure GaAs is phosphide under 2853.

Import Tips & Compliance
• Label shipments clearly as 'undoped test wafers' with no electrical functionality to prevent reclassification as parts of machines
• Include resistivity measurements (>10^7 ohm-cm) in documentation to prove undoped status
• Avoid bulk packaging that could imply industrial chemicals under 28xx; use cleanroom-compatible ESD-safe containers
