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 antioxidant is a compound that itself falls under a different subheading and is present in significant amounts
Other heterocyclic compounds with oxygen hetero-atoms, when the additive changes the product's essential character
If the THF is formulated with multiple additives for a specific industrial application
Prepared chemical products not elsewhere specified, for mixtures beyond simple stabilization
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
• Document the type and concentration of the antioxidant used, as the CBSA may verify it is solely for preservation and not for making the product suitable for a specific use
• Ensure the packaging is compliant with Canadian transportation of dangerous goods regulations, as THF is flammable
• Provide a letter of certification from the manufacturer regarding the peroxide-free status to avoid delays
