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 collector is designed to filter liquids rather than gases
Filtering machinery for liquids is classified under a different subheading within the same heading.
If the collector is presented as a part of the polishing machine
Parts suitable for use solely with a particular machine may be classified with that machine's parts heading.
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
• Classify this as a gas filtration unit, not as a part of the polisher, to benefit from the specific heading
• Keep records of the HEPA filter grade and particle capture efficiency for CBSA verification
• Consider whether the collector is sold separately or with the polisher, as this affects classification
