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 catalyst is unsupported or the precious metal is not on a support material
This subheading covers supported catalysts with precious metal active substances; unsupported catalysts fall under other headings.
If the product is a separate chemically defined compound of precious metals, not a catalytic preparation
Section note 1 excludes separate chemically defined compounds from Chapter 38; they belong in Chapter 28.
If the product is presented as an integral part of a fuel cell assembly, not as a standalone catalyst
Parts of fuel cells are classified in Chapter 85 when they are identifiable as such.

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
• Ensure the product is declared as a supported catalyst with precious metal active substance; misclassification as a chemical compound may lead to penalties
• Verify whether the carbon support is of a kind requiring import permits under Canada's chemical controls
• Keep supplier documentation on platinum content and support material for CBSA verification
