Float Zone Crystal Grower from Germany
Equipment that uses the float zone method to purify and grow semiconductor crystals by melting a narrow zone of polycrystalline silicon with RF heating while moving it along the rod. Classified under HTS 8479.82.00 for its stirring and homogenizing action in zone refining to achieve ultra-pure monocrystalline silicon.

Import Tips
• Include process flow diagrams showing zone melting and homogenization to justify 8479 classification over furnace equipment
• Ensure labeling specifies semiconductor-grade purity levels to prevent misclassification as general lab apparatus
