Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sheets are considered chemical preparations rather than graphite-based semi-manufactures
Heading 38.24 covers other chemical products, which may apply if the graphite is not the primary component.
If the sheets are presented as parts of batteries
Parts of electric accumulators are classified in heading 85.07 when identifiable as such.

Import Tips & Compliance
• Confirm the sheets are not considered separate chemically defined compounds, as chapter note 1 excludes those from Chapter 38
• Provide technical specifications to the CBSA showing the graphite base and silicon content
• Check if the sheets require any special permits under Canadian battery regulations
