99.2% Pure Silicon Ingots for Electronics from Germany
Cylindrical silicon ingots at 99.2% purity, produced via Czochralski method for slicing into semiconductor wafers. Falls under HTS 2804.69.10.00 as unworked elemental silicon with purity 99-99.99%, distinct from higher purity or doped forms. Used in chip fabrication after further refinement.

Import Tips
• Provide manufacturer's assay certificate specifying exact silicon percentage and impurity levels
• Ship in inert atmosphere packaging to prevent oxidation, which could affect purity claims
• Watch for reclassification if ingots exceed 100mm diameter and appear 'worked' per HTS terms
