U.S. imports of optical fibers, optical fiber bundles & cables (excl. individually sheathed fiber cables) (HS 900110) totaled $70.9M in July 2026, traded with 44 countries.
Importers of Optical Fibers, Optical Fiber Bundles & Cables (Excl. Individually Sheathed Fiber Cables) paid $17.7M in duties in July 2026 — an effective duty rate of 26% on $68.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Optical Fibers, Optical Fiber Bundles & Cables (Excl. Individually Sheathed Fiber Cables) imports of $70.9M in July 2026 ran 29% above the year-to-date monthly average of $55.0M.
Last updated: July 2026 dataOptical fibers and fiber bundles in this heading are distinguished from telecommunication-grade fiber optic cables of heading 8544 by their construction: these are bare fibers, bundles, or cables not made up of individually sheathed fibers, used in medical imaging, industrial sensing, and data transmission applications. The US schedule subdivides the heading by material (plastic vs. non-plastic) and application, with lines including 9001100050 (plastic optical fibers), 9001100070 (non-plastic optical fibers), and related bundle and cable lines. Japan and China are the leading suppliers, and imports from China may be subject to Section 301 tariffs depending on the specific 10-digit line.

The critical distinction is construction: heading 9001 covers optical fibers and bundles that are not made up of individually sheathed fibers with connectors or fittings for telecommunications use. Heading 8544 covers fiber optic cables where each fiber is individually sheathed and the cable is designed for voice or data transmission. The end-use application and physical construction — particularly whether fibers are individually sheathed — determine the correct heading, and CBP has issued several binding rulings on this boundary.
Yes. The US schedule separates plastic optical fibers (9001100050) from non-plastic (typically glass) optical fibers (9001100070), and similarly distinguishes plastic fiber bundles and cables (9001100075) from non-plastic ones (9001100085). Duty rates and Section 301 exposure may differ between these lines, so correct material identification at entry is essential.
