5206.12.00.00 - Exceeding 14 nm but not exceeding 43 nm (300)

This HTS category, 5206.12.00.00, specifically classifies single yarns spun from uncombed cotton fibers where the yarn's fineness, measured in "nm" (Ne Millimeter), falls within a specific range. To be classified here, the yarn must have a fineness exceeding 14 nm but not exceeding 43 nm. This category applies to cotton yarn that is not intended for retail sale, meaning it's typically sold in bulk to manufacturers.

The defining characteristic of this category is the precise yarn fineness range. It is distinguished from its siblings by these numerical limits. For instance, 5206.11.00.00 covers yarns that are finer (not exceeding 14 nm), while 5206.13.00.00 and subsequent categories classify yarns that are coarser, exceeding 43 nm. This granular differentiation allows for accurate tracking of different types of cotton yarn based on their thread thickness, which impacts their end-use applications.

As this is a leaf node in the HTS classification system, there are no further subcategories within 5206.12.00.00. Therefore, the classification is final at this level, based solely on the material being cotton, the yarn being single and from uncombed fibers, not put up for retail sale, and falling within the specified fineness range of 14 nm to 43 nm.
