Import Tips
• Include metrology standards certification (e.g
• SEMI specs) for proper optical instrument classification
• Avoid describing as 'machine part' to prevent shift to heading 9033 per Chapter 90 parts rules
• Declare resolution specs (<1nm) to confirm semiconductor-specific use under 9031.41
