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 system primarily filters liquid slurries rather than airborne mists
Liquid filtering machinery is classified separately from gas filtering machinery within heading 84.21.
If the eliminator performs a unique function not typical of standard gas filters
Machines with a specific function not described elsewhere may be classified in this residual 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
• Document the coalescing filtration mechanism to demonstrate it is gas purification, not liquid separation
• Ensure the exhaust connection specifications are clear for CBSA classification
• Check if the mist eliminator is a complete machine or a part, as this changes the applicable tariff item
