Czochralski Crystal Puller for Silicon Wafer Production from China

A specialized machine tool that uses the Czochralski method to grow monocrystalline silicon boules by pulling a seed crystal from molten silicon. The boule is then sliced into wafers for semiconductor fabrication. Classified under HTS 8465.96.0040 as a splitting, slicing, or paring machine for woodworking due to its precision slicing capabilities on hard materials akin to wood processing.

Import Tips

Verify classification against Chapter 84 statistical notes for semiconductor wafer manufacturing equipment to confirm eligibility under this subheading

Provide detailed technical specs and end-use certificates proving it's for boule pulling prior to wafer slicing to prevent reclassification
