Czochralski Crystal Puller Ingot Mold from China
This high-precision ingot mold is designed for use in Czochralski crystal pullers to produce monocrystalline silicon boules for semiconductor wafers. It falls under HTS 8454.90.00.60 as a part of casting machines used in metallurgy for growing pure semiconductor crystals. The mold ensures uniform heat distribution during the crystal growth process.

Import Tips
• Verify material composition (e.g
• high-purity graphite or quartz) meets semiconductor-grade standards to avoid reclassification
• Include detailed technical specs and end-use certification for semiconductor manufacturing to qualify for potential duty relief programs
