Czochralski Crystal Puller from Japan
A mechanical appliance used to grow monocrystalline silicon boules by pulling a seed crystal from molten silicon in the Czochralski process. It projects and controls molten material precisely for semiconductor wafer production, classified under HTS 8424.89.9000 as other appliances for projecting liquids.

Import Tips
• Provide detailed technical specs proving use in semiconductor crystal growth to avoid misclassification as general machinery
• Include end-user certificates from semiconductor fabs for duty preference claims under tech-specific programs
• Verify no fire extinguisher components; common pitfall leads to Chapter 84 reclassification
