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 underfeed mechanism is used for pulverized fuel without a mechanical grate
Burners for pulverized solid fuel are classified under this heading, which may apply if the grate is not mechanical.
If importing the ash removal system separately
Separate parts of stokers, including ash removal appliances, are classified under this heading.

Import Tips & Compliance
• > Confirm the fuel feed mechanism is mechanical (e.g
• screw or ram) and not pneumatic
• Ensure the ash removal system is mechanical and part of the stoker unit
• Provide a clear description of the stoking process to avoid misclassification as a burner
