Czochralski Crystal Puller
A Czochralski crystal puller is specialized equipment used to grow monocrystalline silicon boules from molten silicon, essential for semiconductor wafer production. It is classified as an 'other engine or motor' due to its motor-driven mechanisms for pulling and rotating the crystal.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the puller performs a specific function beyond motor operation
Machines with a specific function other than data processing are classified under heading 84.79.
If the puller is specifically for manufacturing semiconductor devices
Machines used solely or principally for the manufacture of semiconductor boules are classified under heading 84.86.

Import Tips & Compliance
• Provide a full technical specification to the CBSA to demonstrate the motor-driven functions
• Consider whether the puller qualifies as a complete machine under another heading if it includes multiple integrated functions
• Verify if the equipment is eligible for duty deferral under the Machinery Program
