Product classification
HS code for Optical mirror: 9001.90
Optical elements, lenses n.e.c. in heading no. 9001, prisms, mirrors and other optical elements, unmounted, of any material (excluding elements of glass not optically worked).
Classification of optical mirror under HS 9001.90
Optical mirrors are classified under HS code 9001.90 when they are unmounted. This classification is part of Chapter 90, which covers optical, photographic, and cinematographic instruments. To qualify for this heading, the mirror must be "optically worked." This means that at least one of its surfaces has been ground and polished to a high degree of precision to produce specific optical effects, such as reflection with minimal distortion. These mirrors can be made of glass, metal, or other materials like plastic. The 9001.90 code is a residual category for optical elements that are not lenses, prisms, or optical fibers. The defining characteristic is that the mirror is presented as a standalone component without any frame or mounting that would allow it to be immediately installed into a device.

Codes often confused with 9001.90
Common mistake. A frequent misclassification is using HS code 7009, which covers glass mirrors. However, 7009 specifically excludes mirrors that are optically worked. If a mirror has been precision-ground for optical use, it must move to Chapter 90. Another common error is using 9002.90; this code is only for mirrors that are already mounted in a frame or holder. If the mirror is a simple glass pane without optical working, it remains in Chapter 70.
Top exporters and importers of HS 900190 (the code used for optical mirror), 2025
In 2025, the largest exporter of HS 900190 (the code used for optical mirror) in UN Comtrade data was China, with 34% of world exports; the largest importer in UN Comtrade data was China, with 26% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 900190, not only optical 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 optical mirror
What is the HS code for Optical mirror?
The HS code for Optical mirror is 900190 (Optical elements; lenses n.e.c. in heading no. 9001, prisms, mirrors and other optical elements, unmounted, of any material (excluding elements of glass not optically worked)). The HS code for an unmounted, optically worked mirror is 9001.90. If it is mounted, the code is 9002.90.
How do I classify Optical mirror for customs?
Optical mirror is classified under HS code 900190 — Optical elements; lenses n.e.c. in heading no. 9001, prisms, mirrors and other optical elements, unmounted, of any material (excluding elements of glass not optically worked). This is a 6-digit subheading level code.
What does optically worked mean for a mirror?
It means the surface has been processed (usually by grinding and polishing) to achieve a specific curvature or flatness required for precision optical performance.
Which countries are the top exporters of optical mirror (HS 900190)?
In 2025, the top exporters of HS 900190 (the code used for optical mirror) in UN Comtrade data were China ($3.7B, 34% of world exports), Hong Kong ($1.2B) and Taiwan (about $1.2B). World exports came to about $10.9B, 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 optical mirror (HS 900190)?
In 2025, the top importers of HS 900190 (the code used for optical mirror) in UN Comtrade data were China ($2.8B, 26% of world imports), Hong Kong ($1.1B) and Vietnam (about $1.0B). World imports came to about $10.5B, 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.
Is the HS code for Optical mirror the same in all countries?
The base HS code 900190 for Optical 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 optical mirror in Brazil?
Brazil splits HS 900190 into 2 NCM codes, so the right one for optical mirror depends on the product's details: 9001.90.10 (Other unmounted lenses), 9001.90.90 (Unmounted prisms, mirrors and optical elements).
