Import Tips
• Provide manufacturer specs linking the shaft to float zone methods per statistical note (a)(i) for clean classification
• Ensure no secondary machining has occurred, as finished shafts may shift to other part subheadings
• Document vacuum/heat resistance ratings to prove semiconductor end-use and avoid general machinery classification
