U.S. imports of monoculars, optical telescopes & astronomical instruments (HS 900580) totaled $7.6M in April 2026, traded with 36 countries.
Importers of Monoculars, Optical Telescopes & Astronomical Instruments paid $1.3M in duties in April 2026 — an effective duty rate of 18% on $7.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataOptical telescopes and astronomical instruments occupy a technically specialized corner of the optics schedule, with the US tariff lines separating infrared-capable telescopes (9005804020), other optical telescopes (9005804040), and non-telescope astronomical instruments and mountings (9005806000). China leads imports, but Austria and Japan — both known for precision optical manufacturing — are significant sources, reflecting the heading's mix of consumer-grade and research-quality instruments. Importers of infrared or night-vision-capable telescopes should evaluate dual-use licensing obligations under the EAR before entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
When imported together as a complete instrument, the mounting is generally classified with the telescope under 9005804040 or the appropriate subheading. Mountings imported separately may fall under 9005806000 as astronomical instrument mountings, or potentially under a parts provision. The key classification factor is whether the mounting is presented with the optical instrument or as a standalone article.
Technical specifications — aperture, focal length, optical coatings, and intended application — help establish whether an instrument is a consumer product or a precision scientific instrument. For high-value research equipment, a detailed manufacturer's specification sheet and, where applicable, an end-use certificate may be requested by CBP to confirm classification and admissibility.
