Czochralski Crystal Puller from China
A Czochralski crystal puller is a machine used to produce extremely pure monocrystalline semiconductor boules, such as silicon, from which wafers are sliced. It employs the Czochralski method by dipping a seed crystal into molten silicon and slowly pulling it upward to form a single crystal boule. This equipment falls under HTS 8486.10.00.00 as it is specifically for the manufacture of semiconductor boules.

Import Tips
• Verify equipment is solely for semiconductor boule manufacture per Chapter 84 Note 11 to avoid misclassification
• Provide detailed technical specs and end-use certificates to customs for duty-free qualification under certain trade agreements
