Crystal Boule Grinder from United States
A precision grinding machine with a self-contained electric motor that shapes semiconductor crystal boules to exact wafer diameters and grinds orientation flats indicating conductivity and resistivity. This machine prepares boules for subsequent wafer slicing. It is a specialized machine with an individual function, not specified elsewhere in Chapter 84, so it is classified under 8479.89.90.

Import Tips
• Document the machine's specific function in grinding semiconductor boules, as this may support classification under heading 84.86 if it is used solely in semiconductor manufacturing
• Check if the equipment qualifies for the Accelerated Capital Cost Allowance (ACCA) for clean energy or manufacturing equipment
• Ensure the grinder's electrical specifications comply with Canadian standards to avoid customs holds
