SITCSection 7
U.S. imports of connectors for optical fibers, bundles & cables (SITC 77256) totaled $81.7M in April 2026, traded with 52 countries.
Importers of Connectors for Optical Fibers, Bundles & Cables paid $7.4M in duties in April 2026 — an effective duty rate of 12% on $62.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataOptical fiber connectors — including LC, SC, ST, MTP/MPO, and FC types — are precision-engineered passive components that enable low-loss signal coupling in telecommunications networks, data centers, and fiber-to-the-premises deployments. Unlike copper electrical connectors, these devices are classified by their optical function rather than voltage rating, placing them in a distinct trade category that reflects the fiber-optic infrastructure build-out driving global demand. Connector performance specifications such as insertion loss, return loss, and polish type (UPC vs. APC) are commercially critical distinctions that importers and procurement teams should document alongside country-of-origin information.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Pre-terminated patch cords — fiber cables with connectors already installed — are generally classified as fiber-optic cables or cable assemblies rather than as connectors, because the cable imparts the essential character of the finished assembly. Loose connectors or connector kits without attached cable classify under the connector heading. The distinction matters for tariff purposes and should be confirmed based on the specific product configuration.
UPC (ultra-physical contact) and APC (angled physical contact) connectors differ in ferrule end-face geometry and are not interchangeable in the field. For trade documentation purposes, the polish type should be stated on the commercial invoice and packing list because it affects product identity, return-loss performance claims, and compatibility with end-use network equipment — all of which may be relevant to CBP's assessment of the goods as described.
