Import Tips
• Ensure the spindle assembly is declared as a part of semiconductor processing equipment, not as a general machine tool part
• Provide evidence of its principal use with machines of headings 84.70 to 84.72 to support classification
• Consider the end-use of the equipment to determine if any duty deferral programs apply
