8465.91.00.27/Czochralski Crystal Puller/China

Czochralski Crystal Puller from China

A Czochralski crystal puller is used to produce extremely pure monocrystalline semiconductor boules, such as silicon, from which wafers are sliced for semiconductor manufacturing. It falls under HTS 8465.91.00.27 as specialized sawmill machines adapted for precise sawing in wafer preparation from crystal boules in semiconductor processing. This equipment aligns with statistical notes for wafer manufacturing equipment including crystal growers and pullers.

Import Tips

• Verify equipment is specifically for semiconductor boule processing to qualify under statistical provisions; provide detailed technical specs and end-use certificates

• Common pitfall: misclassification as general machinery without wafer prep documentation

• Ensure FDA or export control compliance if handling high-purity materials
