Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the flakes are of a cyanide salt other than sodium, such as potassium cyanide.
The tariff item covers only sodium cyanide; other metal cyanides are classified under the sibling item.
If the product is a complex cyanide, such as a double salt, rather than a simple sodium cyanide.
Complex cyanides are classified in heading 28.42 per Chapter 28 Note 5.

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
• Confirm the flake form is pure sodium cyanide without anti-caking agents that could change classification
• Ensure compliance with Canadian hazardous materials regulations for shipping
• Keep the commercial invoice and packing list detailed for CBSA inspection
