Last updated: August 2026 dataBolducs are a specialized narrow-fabric construction in which warp yarns are held together solely by an adhesive rather than interlaced weft threads, producing a flat, ribbon-like tape used in packaging, garment finishing, and industrial bundling. The entire heading consolidates into a single 10-digit tariff line, 5806400000, simplifying classification but requiring importers to confirm the adhesive-assembly method distinguishes the product from woven narrow fabrics under adjacent headings. Because the construction is defined by process rather than fiber content, the fiber composition still influences applicable textile quota categories and visa requirements where relevant.

A bolduc consists entirely of warp yarns bonded by adhesive with no interlaced weft, whereas a woven narrow fabric requires actual interlacing of warp and weft. If the adhesive-assembly method cannot be confirmed, the product may be reclassified under a woven narrow-fabric heading, changing the applicable duty rate and textile category.
At the 10-digit US HTS level, heading 5806.40 resolves to a single line (5806400000) regardless of fiber content. However, fiber composition remains relevant for determining textile visa or export license requirements and for applying any applicable textile trade-remedy measures.
