Mounted Neutral Density Optical Filter
A mounted neutral density filter used in photographic and scientific instruments to reduce light intensity without altering color balance. It falls under HTS 9002.20.80.00 as a mounted optical filter that is a part or fitting for optical instruments, not unworked glass. These filters are essential for cameras, projectors, and laboratory spectrometers.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unmounted or not specifically for instrument fitting
Unmounted optical elements, including filters, are classified in 9001 as they lack the mounting required for 9002 instrument parts.
If glass not optically worked
Basic glass filters without optical processing or mounting fall under glassware of heading 7016, per Chapter 90 exclusions.
If parts of specific machines like data processing equipment
If principally for computers or office machines, classification shifts to Section XVI per note 3, overriding Chapter 90.

Import Tips & Compliance
• Verify the filter is mounted and specifically designed as a part for optical instruments to avoid reclassification under unmounted glass elements
• Provide detailed technical specs and end-use documentation to confirm exclusion from Chapter 90 note exclusions like machine parts
• Check for optical working certification to distinguish from basic glass filters under heading 7007
