Chemical Synthesis Silicon Chunks from China
Irregular silicon chunks with 98-99% purity, used for organosilicon compound manufacturing like silanes. These are chemically defined elemental silicon in chunk form, meeting Chapter 28 Note 1 requirements. They are classified as 'other' silicon under this tariff item, as the purity is below 99.99% and the chunks are not doped for electronics.

Import Tips
• Ensure the chunks are not doped for electronics and are in unworked form
• Provide a certificate of analysis showing silicon purity (98-99%) and impurity levels
• Declare the goods as elemental silicon for chemical synthesis, but note that end-use does not affect classification
