HS-4 · Heading
3507 — Enzymes; prepared enzymes not elsewhere specified or included
Chapter 35: Albuminoidal substances
Plain-language overview
Use HS-4 3507 when importing prepared enzymes, such as rennet used in cheese-making or other enzyme preparations not specified elsewhere. For instance, if you're bringing in a rennet concentrate for dairy production, this is the correct heading.
When deciding between the HS-6 lines, consider the specific type of enzyme. HS-6 350710 covers rennet and its concentrates, while HS-6 350790 includes all other prepared enzymes. If your product is a general enzyme blend for baking, you would classify it under 350790.
If you import a product that contains both rennet and other enzymes, you may need to separate them for classification. Rennet-based products must go under 350710, while any other enzyme preparations would fall under 350790. Ensure you have the correct documentation to support your classification.
