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 centrifuges are presented separately without the cascade configuration
Standalone centrifuges for general separation are classified under centrifuges, not isotopic separation apparatus.

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
• > Classify the assembly as a complete unit, not as individual centrifuges, to benefit from the heading for isotopic separation apparatus
• Prepare a detailed flow diagram and specification sheet for CBSA to confirm the system's dedicated function
• Check whether the assembly requires a permit under Canada's Nuclear Non-Proliferation Import and Export Control Regulations
