U.S. imports of stereoscopic microscopes (SITC 87141) totaled $17.5M in July 2026, traded with 21 countries.

Importers of Stereoscopic Microscopes paid $2.0M in duties in July 2026 — an effective duty rate of 12% on $17.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Stereoscopic Microscopes imports of $17.5M in July 2026 ran 31% above the year-to-date monthly average of $13.4M.

Last updated: July 2026 data

Stereoscopic microscopes — also called stereo or dissecting microscopes — provide three-dimensional low-magnification views and are workhorses in electronics assembly, surgical training, gemology, forensic examination, and biological specimen preparation. Their dual optical path and wide working distance distinguish them from compound microscopes, and that design difference is the basis for their separate SITC classification. Japan has historically been a leading source of precision stereo microscopes, with a growing share of volume-tier instruments manufactured in China.

Frequently Asked Questions

What separates a stereoscopic microscope from a compound optical microscope for classification purposes?

Stereoscopic microscopes use two separate optical paths angled slightly apart to produce a three-dimensional image at relatively low magnification, typically with a long working distance. Compound microscopes use a single optical axis and achieve much higher magnification for thin-section specimen work. This functional and structural difference places them in separate SITC headings, and the distinction is important because duty rates at the HTS level may differ.

Are zoom stereo microscopes with integrated digital cameras classified differently from standard stereo microscopes?

A stereo microscope with an integrated camera generally retains its classification as a microscope if the optical microscopy function is the essential character of the complete unit. The camera is treated as an accessory. However, if the digital imaging system is the dominant component by value and function, reclassification under a different heading could be argued — importers should review the specific configuration with a customs broker.
