Harmonized System
Ultra-fine single uncombed blended cotton yarn exceeding 80 metric number per single yarn is a specialty product used in fine lightweight fabrics where a cotton-blend specification is required. Italy and Denmark are the leading US suppliers — both European origins with established fine-spinning traditions — reflecting the technical demands of producing uncombed yarn at counts above 80 NM in a blended fiber system. The heading resolves to a single US tariff line (5206150000). The combination of high count, uncombed fiber, and sub-85% cotton content makes this a relatively narrow commercial niche, and importers should ensure mill documentation clearly states both the NM count and the fiber composition.

While combing is standard for high-count pure cotton yarns, certain blended fiber systems — particularly those incorporating synthetic or man-made fibers — can achieve fine counts without a combing step because the non-cotton component contributes to yarn strength and evenness. The classification distinction between combed and uncombed is based on the processing of the cotton fiber component specifically.
Importers should obtain a mill certificate or independent laboratory test report confirming the metric number per single yarn. A result at or below 80 NM classifies in 520614; a result above 80 NM classifies in 520615. Given that the two headings may carry different duty rates, accurate count documentation is essential before filing the entry summary.
