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 hood is imported without its fan or as a component of a larger system
A hood without an integrated fan may be classified as a part under heading 84.14 rather than a complete hood.
If the laminar flow hood performs a specific function beyond ventilation, such as contamination control in a manufacturing process
Machines with a specific function other than ventilation may fall under heading 84.79.

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 HEPA filter specifications and ISO Class 5 certification to support classification as a ventilating hood
• Verify that the hood's fan and electrical components meet Canadian Electrical Code requirements
• If the hood is part of a larger cleanroom system, consider whether it should be classified separately or as a functional unit
