Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the scrap has been remelted into ingots or other unwrought forms.
Remelted hafnium would be classified as unwrought hafnium, not waste and scrap, under the same tariff item.
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
• Ensure the scrap is not contaminated with radioactive materials from nuclear use; provide a certificate of non-contamination if applicable
• Separate hafnium scrap from other metals to avoid misclassification under Section Note 7
• Declare the weight and form (clippings, turnings) accurately to the CBSA
