Product classification
HS code for Mounted filter: 9002.20
Filters, mounted as parts or fittings for instruments or apparatus, of any material (excluding elements of glass not optically worked).
Classification of mounted filter under HS 9002.20
Mounted filters for instruments or apparatus are classified under HS code 9002.20. This classification falls within Chapter 90, which encompasses optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9002 specifically covers lenses, prisms, mirrors, and other optical elements, of any material, mounted, being parts of or fittings for instruments or apparatus, other than such elements of glass not optically worked. Subheading 9002.20 is the specific designation for filters. These are optical components designed to selectively transmit or block specific wavelengths of light. The "mounted" requirement means the filter must be set in a frame, holder, or similar attachment that allows it to be fitted into an instrument. This distinguishes them from unmounted optical elements found in heading 9001. The material can be glass, plastic, or other substances, provided they are optically worked. This code is essential for components used in cameras, laboratory equipment, and industrial sensors where light filtration is a functional necessity.

Codes often confused with 9002.20
Common mistake. A common error is classifying mounted filters under heading 8421, which covers machinery and apparatus for filtering or purifying liquids or gases. HS code 9002.20 is strictly for optical filters. Another common mistake is using 9001.20, which is for unmounted polarizing material. If the filter is not mounted in a frame or housing, it belongs in heading 9001. Furthermore, if the filter is an integral part of a camera lens assembly, it might be confused with 9002.11, though 9002.20 remains the specific code for the filter itself.
Top exporters and importers of HS 900220 (the code used for mounted filter), 2025
In 2025, the largest exporter of HS 900220 (the code used for mounted filter) in UN Comtrade data was the United States, with 27% of world exports; the largest importer in UN Comtrade data was South Korea, with 26% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
