Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of glass not optically worked
Chapter 70 covers unworked glass mirrors; optical working via coatings moves it to Chapter 90.
If mounted in a frame or housing
Mounted mirrors become parts of optical instruments under heading 9013, not unmounted elements.
If common base metal construction for decorative use
Chapter 83 covers decorative or functional metal mirrors, excluding precision optical elements.

Import Tips & Compliance
• 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
