5205.31.00.00 - Not exceeding 14 nm per single yarn (300) 🖩

This HTS category, 5205.31.00.00, specifically classifies multiple (folded) or cabled cotton yarn, derived from uncombed fibers, where each single yarn within the ply or cable measures not exceeding 14 tex (equivalent to not exceeding 300 nm). These yarns must contain 85 percent or more by weight of cotton and are not intended for retail sale. Examples include multi-ply yarns used in industrial textiles, such as canvas or certain types of upholstery fabric, where the fineness of the individual strands is a key determinant.

The primary distinction of this subcategory lies in the fineness of the individual yarn components. Unlike its sibling categories, which cover single yarns exceeding 14 tex (e.g., 5205.32.00.00 for yarns between 14 and 43 tex, and so on for coarser yarns), 5205.31.00.00 is for the finest of these multiple-ply or cabled uncombed cotton yarns. This narrow range of yarn fineness is crucial for accurate duty assessment and trade statistics.

As this is a leaf node within the HTS, there are no further subcategories under 5205.31.00.00. Classification within this code is definitive based on the yarn construction (multiple or cabled), fiber content (85% or more cotton), fiber preparation (uncombed), and specifically, the linear density of the single yarn comprising the folded or cabled structure.
