Import Tips
• Verify the mirror's coating specifications and substrate material to confirm it qualifies as an unmounted optical element under Chapter 90
• Provide detailed technical datasheets showing reflectivity curves and wavelength range to support classification during customs review
• Avoid misclassification as finished optical instruments by ensuring no mounting hardware is included
