Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unmounted or glass not optically worked
Unmounted or simply cut glass optical elements classify in 9001, not mounted parts for instruments.
If dedicated solely to laser apparatus
Parts principally for specific Chapter 90 instruments like lasers may classify with the apparatus in 9013.
If for industrial machine technical use
Chapter 90 excludes articles for machines/appliances of technical use in Section XVI like 8486.

Import Tips & Compliance
• Verify optical working certification to distinguish from unworked glass elements excluded from this heading
• Include detailed instrument compatibility specs in documentation to prove 'parts for instruments' classification
• Avoid misclassification as machine parts under Section XVI by emphasizing optical function
