Czochralski Crystal Puller Roll from Germany
A precision roll used in Czochralski method crystal growers to pull monocrystalline silicon boules for semiconductor wafer production. It falls under HTS 8455.30.00.65 as a roll for rolling mills weighing under 2,268 kg, specifically for processing semiconductor materials into precise diameters. This equipment supports the initial boule formation critical for wafer slicing.

Import Tips
• Verify roll weight certification below 2,268 kg to qualify for this subheading; provide manufacturer specs on semiconductor boule processing use
• Ensure documentation links to Chapter 84 statistical notes for semiconductor equipment
• Avoid misclassification as general metal rolls by detailing monocrystalline material application
