Czochralski Crystal Puller from China
A specialized machine used in semiconductor manufacturing to grow monocrystalline silicon boules by slowly pulling a seed crystal from molten silicon using the Czochralski method. It falls under HTS 8479.82.00 as a mixing or stirring machine due to the precise stirring and homogenization of the melt to ensure crystal purity and uniformity.

Import Tips
• Verify machine function matches statistical notes for semiconductor processing to avoid reclassification to Chapter 84 heading 8486
• Provide detailed technical specs and end-use certificates proving semiconductor application for preferential tariff treatment
