Product classification
HS code for Mounted mirror: 9002.90
Optical elements, n.e.c. in heading no. 9002 (e.g. prisms and mirrors), mounted, being parts or fittings for instruments or apparatus, of any material (excluding elements of glass not optically worked).
Classification of mounted mirror under HS 9002.90
Mounted mirrors and other optical elements not elsewhere classified within heading 9002 are assigned HS code 9002.90. This code is situated in Chapter 90, which covers precision instruments and optical components. Heading 9002 specifically addresses mounted optical elements that serve as parts or fittings for instruments. Subheading 9002.90 is a residual category for items such as prisms and mirrors that do not fit into the specific subheadings for objective lenses or filters. These mirrors are typically high-precision components used to reflect light within an optical path of a scientific, medical, or industrial device. Unlike standard decorative mirrors, these must be "optically worked"—meaning their surfaces have been processed to achieve specific optical properties—and they must be mounted in a frame or support. This classification is essential for components used in lasers, surveying equipment, and laboratory apparatus where precise light manipulation is required. The mounting must be designed to fit into a specific instrument or apparatus to qualify under this heading.

Codes often confused with 9002.90
Common mistake. Mounted mirrors are often misclassified under heading 7009, which covers glass mirrors for general use (like bathroom or rearview mirrors). However, if the mirror is for an optical instrument and is optically worked, it must be in Chapter 90. Another common error is using 9001.90, which is for unmounted optical elements. If the mirror is not in a frame or holder, it belongs in 9001. Finally, mirrors that are already part of a complete instrument (like a microscope) should be classified with the instrument itself unless they are being imported as separate parts.
Top exporters and importers of HS 900290 (the code used for mounted mirror), 2025
In 2025, the largest exporter of HS 900290 (the code used for mounted mirror) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was China, with 29% of world imports. Taiwan did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 0.4% of its imports here ($1.6M, CEPII BACI), so it may also belong among the top importers.
Figures cover everything classified under HS 900290, not only mounted mirror.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).

Questions about mounted mirror
What is the HS code for Mounted mirror?
The HS code for Mounted mirror is 900290 (Optical elements; n.e.c. in heading no. 9002 (e.g. prisms and mirrors), mounted, being parts or fittings for instruments or apparatus, of any material (excluding elements of glass not optically worked)). The HS code for mounted mirrors and other optical elements (excluding lenses and filters) for instruments is 9002.90.
How do I classify Mounted mirror for customs?
Mounted mirror is classified under HS code 900290 — Optical elements; n.e.c. in heading no. 9002 (e.g. prisms and mirrors), mounted, being parts or fittings for instruments or apparatus, of any material (excluding elements of glass not optically worked). This is a 6-digit subheading level code.
Are automotive rearview mirrors classified here?
No, automotive rearview mirrors are generally classified under HS code 7009.10, as they are not considered high-precision optical elements for instruments.
Which countries are the top exporters of mounted mirror (HS 900290)?
In 2025, the top exporters of HS 900290 (the code used for mounted mirror) in UN Comtrade data were China ($1.0B, 19% of world exports), Taiwan (about $989M) and the Netherlands ($732M). World exports came to about $5.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of mounted mirror (HS 900290)?
In 2025, the top importers of HS 900290 (the code used for mounted mirror) in UN Comtrade data were China ($1.5B, 29% of world imports), the Netherlands ($749M) and South Korea ($511M). World imports came to about $5.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Taiwan did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 0.4% of its imports here ($1.6M, CEPII BACI), so it may also belong among the top importers.
Is the HS code for Mounted mirror the same in all countries?
The base HS code 900290 for Mounted mirror is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for mounted mirror in Brazil?
Brazil splits HS 900290 into 2 NCM codes, so the right one for mounted mirror depends on the product's details: 9002.90.10 (Optomechanical switches for optical networks), 9002.90.90 (Other mounted optical elements).
