Import Tips
• Verify compatibility with specific microscope models via manufacturer specs for proper classification under heading 9012
• Include detailed technical datasheets in documentation to prove principal use with non-optical microscopes
• Avoid misclassification as general optical parts (9002); ensure end-use declaration specifies SEM or TEM application
