Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ingots are cut into wafers or discs for electronics.
Chapter 28 Note 8 directs such forms to heading 38.18.

Import Tips & Compliance
• Ensure the ingots are not doped or sliced into wafers, as that would reclassify them under heading 38.18
• Keep records of the silicon purity and ingot form for CBSA verification
• If the ingots contain impurities, confirm they are within the tolerance for chemically defined elements under Chapter 28 Note 1
