Czochralski Crystal Puller from China
A machine used to produce extremely pure monocrystalline semiconductor boules from molten silicon using the Czochralski method, from which wafers are sliced. It falls under HTS 8486.40.00 as apparatus specified in note 11(C) for semiconductor boule manufacturing. Essential for creating high-purity crystals in semiconductor production.

Import Tips
• Verify equipment qualifies under Note 11(C) with technical specs proving semiconductor boule use; general crystal growers may shift classification
• Provide end-user certificates showing exclusive semiconductor application to avoid reclassification as lab apparatus
• Ensure BIS export license compliance if from controlled origins, as semiconductor tools face strict controls
