Czochralski Crystal Puller from China
A machine tool used to grow monocrystalline silicon boules by pulling a seed crystal from molten silicon in the Czochralski method. It removes excess material through precise shaping and grinding processes to achieve the required boule diameter and flats, classifying it under HTS 8461.90.60 as other semiconductor manufacturing equipment involving metal/cermet removal.

Import Tips
• Verify equipment qualifies under statistical notes for semiconductor wafer manufacturing to avoid reclassification
• Provide detailed technical specs and end-use certificates to customs for duty preference claims
