Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a pure enzyme not immobilized or not presented as a catalyst
Enzymes are classified in heading 35.07 when not put up as catalytic preparations.
If the product is mixed with foodstuffs or nutritive substances
Mixtures with foodstuffs are excluded from chapter 38 by note 1(b).

Import Tips & Compliance
• Ensure the enzyme is presented as an immobilized catalyst, not as a pure enzyme of chapter 35; the immobilization and catalytic use are key
• Provide documentation on the enzyme activity and immobilization support for CBSA verification
• If the product is used in food production, ensure compliance with Canadian Food Inspection Agency (CFIA) requirements
