Silicon Carbide Ingot for Semiconductor Wafer Production from Germany
A large cultured silicon carbide crystal grown via physical vapor transport method, weighing over 2.5 grams, supplied in ingot form before slicing into wafers. Classified under HTS 3824.99.1100 as cultured crystals (not optical elements) in ingot shape for industrial applications like power electronics. These ingots provide superior thermal conductivity and hardness essential for high-performance semiconductors.

Import Tips
• Verify crystal purity certification (e.g
• >99.99% SiC) and weight documentation to confirm HTS 3824.99.1100 classification over Chapter 28 inorganic chemicals
• Include material safety data sheets (MSDS) and end-use statements for semiconductor fabrication to avoid reclassification as basic chemicals
