Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unmounted prisms or partially worked
Unmounted optical elements classify in 9001/9002, not assembled appliances.
If imported as replacement part for specific 9013 apparatus
Parts principally for named 9013 instruments stay in heading per note 2(a).
If plastic beam splitters for low-power applications
Plastic optical elements classify by material in chapter 39.
