Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the blade is an interchangeable tool for hand tools or machine tools
Heading 82.07 covers interchangeable tools for working materials, including saw blades, which may take precedence over a machinery part classification.
If the blade is specifically designed for machines used in the manufacture of semiconductor boules or wafers
Heading 84.86 covers machines and apparatus for the manufacture of semiconductor devices, including their parts, which may be more specific than 8487.

Import Tips & Compliance
• > Be aware that if the blade is presented as an interchangeable tool, it may be classified under heading 82.07 rather than 8487—review the product's packaging and invoicing to ensure consistency
• Provide CBSA with the blade's specifications, including diamond grit size and dimensions, to support the classification
• Consider whether the blade is a wear part; if so, it may be subject to different tariff treatment than a machinery part
