Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the granules are doped and presented as discs, wafers, or similar forms.
Chapter 28 Note 8 excludes doped elements in cut forms, directing them to heading 38.18.

Import Tips & Compliance
• Verify the ampoules are sealed and labeled with purity and lot number to assist CBSA inspection
• Since the arsenic is for semiconductor use, confirm it is not doped; if doped, ensure it is in unworked rod or cylinder form to stay in this heading
• Check if the product requires a permit under Canada's Export and Import Permits Act for controlled substances
