Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If optically worked but unmounted
Optically worked glass mirrors without mount go here, changing from 'other mirrors' subheading.
If part of measuring instrument
Mirrors principally for optical measuring devices classify under 9031 per chapter note on measuring instruments.
If bulk plastic mounted for general use
Plastic-mounted mirrors not exclusive to chapter 90 instruments classify by material per exclusion notes.

Import Tips & Compliance
• Include technical drawings showing mounting and optical specs; ensure invoices specify 'for optical instruments'; watch for reclassification if used in non-optical machinery
