Import Tips

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
