Czochralski Crystal Puller from Japan
A machine that uses the Czochralski method to grow monocrystalline silicon boules from molten semiconductor material, which are later sliced into wafers for electronic device fabrication. Classified under HTS 8475.10.00.00 as it assembles components into glass envelopes during the initial crystal growth phase for lamps or tubes. Essential for producing high-purity silicon used in electric lamps and semiconductor processing.

Import Tips
• Verify machine specifications confirm use for glass envelope assembly in lamp production to avoid reclassification to Chapter 84 semiconductor equipment
• Provide detailed technical documentation on crystal growth process and glass envelope integration during customs valuation
