HS Code for Mounted filter

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.

Common Misclassification

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.

FAQ

What is the HS code for Mounted filter?

The HS code for mounted filters that are parts or fittings for instruments or apparatus is 9002.20.

Are water filters classified under this code?

No, water filters are classified under heading 8421 as they are mechanical filtering devices for liquids, not optical elements.
