Czochralski Crystal Puller from Germany
A casting machine used in semiconductor manufacturing to grow monocrystalline silicon boules via the Czochralski method by pulling a seed crystal from molten silicon. It falls under HTS 8454.30.00 as a specialized casting machine employed in metallurgy for producing high-purity ingots from which semiconductor wafers are sliced.

Import Tips
• Verify machine specifications confirm use in metallurgical casting processes, with documentation on silicon boule production
• Obtain certificates proving high-purity semiconductor-grade materials handling to avoid reclassification
