More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the silicon is cut into discs, wafers, or similar forms for electronics.
Chapter 28 Note 8 excludes doped silicon in disc or wafer form, which falls under heading 38.18.

Import Tips & Compliance
• Ensure the silicon content is certified at 99.99% or higher by weight, as this determines classification under 2804.61.00
• Provide a mill test certificate or lab analysis to the CBSA to support the declared purity
• If the rods are doped for electronics, verify they remain in unworked form (e.g
• as drawn) to stay in this heading
