U.S. imports of stereoscopic microscopes (HS 901110) totaled $19.3M in April 2026, traded with 14 countries.
Importers of Stereoscopic Microscopes paid $2.2M in duties in April 2026 — an effective duty rate of 11% on $19.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Stereoscopic Microscopes imports of $19.3M in April 2026 ran 45% above the year-to-date monthly average of $13.3M.
Last updated: April 2026 dataStereoscopic microscopes — which provide three-dimensional, low-magnification views and are widely used in electronics assembly, surgical training, gemology, and biological dissection — are split in the US tariff schedule between units equipped with image-capture capability (9011104000) and all other stereoscopic models (9011108000), with a legacy line (9011100000) also present. Germany is the dominant supplier to the US, reflecting the global leadership of German precision optics manufacturers in this segment; Singapore and China are also significant sources. Buyers should be aware that Chinese-origin stereoscopic microscopes may be subject to Section 301 tariffs, while German-origin instruments are not currently subject to comparable trade remedy measures.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A stereoscopic microscope uses two separate optical paths — one for each eye — to produce a three-dimensional image at relatively low magnification, typically for manipulation or inspection tasks. Compound optical microscopes (heading 9011.80) use a single optical path and achieve much higher magnification for viewing thin specimens. The design of the optical system, not the magnification range alone, determines the correct heading.
Yes — the US tariff schedule specifically separates stereoscopic microscopes with means to photograph the image (9011104000) from those without (9011108000). If a camera or digital imaging module is integrated into the microscope at the time of importation, the unit should be classified under the imaging-capable line, which may carry a different duty rate.
