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 rods are doped for electronics use
Doped chemical elements in unworked forms fall under heading 28.53, not 28.04, per Chapter 28 Note 8.
If the rods are cut into discs, wafers or similar forms
When cut into semiconductor wafers or discs, doped elements are excluded from Chapter 28 and classified under heading 38.18.

Import Tips & Compliance
• Ensure the product is accompanied by a certificate of analysis confirming purity, as the CBSA may verify it is uncompounded elemental tellurium
• Declare the end use (research or semiconductor manufacturing) to support classification under this non-metal heading
• No import permit is typically required for elemental tellurium, but verify with the CBSA for any controlled end-use restrictions
