Last updated: August 2026 dataOptical fiber cables composed of individually sheathed fibers serve as the physical backbone of broadband, telecommunications, and data-center infrastructure — a sector seeing sustained US import demand driven by network expansion. The entire heading resolves to a single 10-digit line (8544700000), so classification disputes typically center on whether fibers are individually sheathed versus bundled without individual sheathing, which would push the product to a different heading. Mexico is the leading supplier to the US market, with Vietnam and Japan also prominent sources. Importers sourcing from Vietnam or Indonesia should verify country-of-origin documentation carefully, as fiber cable assembly operations can span multiple countries.

The defining requirement is that each fiber within the cable must be individually sheathed. Cables where fibers are grouped in a common buffer tube without individual sheathing typically fall outside this heading. Importers should obtain technical specifications from the manufacturer confirming individual sheathing to support the classification.
Because fiber cable production often involves drawing fiber in one country and jacketing or connectorizing in another, a substantial-transformation analysis is required. Importers should obtain a detailed bill of materials and manufacturing process statement from the supplier to support the origin determination, particularly for cables assembled in Vietnam or Indonesia where multi-country production is common.
