Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tablets 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 tablets contain binders or additives that make them a preparation.
Additives beyond stabilizers or anti-dusting agents may classify the product as a preparation.
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
• Declare the 98% assay and any impurities on the commercial invoice to ensure accurate classification
• Ensure the tablets are packed in UN-approved HDPE supersacks for dangerous goods
• Provide a SDS to CBSA for safety compliance
