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 graphite is not in powder form but in other physical states
Covers natural graphite not in powder or flakes, such as granular or lump forms.
If the graphite is mixed with other chemicals to create a fire retardant compound
Mixtures of graphite with other substances are excluded from Chapter 25 and fall under chemical products.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify that the purification process does not alter the graphite's crystalline structure, as chemical changes could shift classification
• Provide a safety data sheet (SDS) to the CBSA, as expandable graphite may have specific handling requirements
• Confirm the product is not mixed with binders or resins, which would exclude it from Chapter 25
