5206.33.00.00 - Exceeding 43 nm but not exceeding 52 nm per single yarn (300)

This HTS category, 5206.33.00.00, specifically classifies multiple (folded) or cabled cotton yarns, not put up for retail sale, where the single yarn component falls within a defined fineness range. These yarns are characterized by containing less than 85 percent by weight of cotton, and the fineness of each individual strand, when measured in "nm" (number of meters per gram of yarn), exceeds 43 but does not exceed 52. This fineness criterion is crucial for distinguishing this product from other cotton yarns.

The distinction from its sibling categories lies precisely in this yarn fineness. For instance, 5206.31.00.00 covers yarns with a single strand not exceeding 14 nm, while 5206.32.00.00 encompasses yarns between 14 nm and 43 nm. Conversely, 5206.34.00.00 and 5206.35.00.00 cover yarns exceeding 52 nm. Therefore, classification under 5206.33.00.00 depends strictly on measuring the "nm" of the constituent single yarn within the specified range.

As this is a leaf node within the HTS, there are no further subcategories that subdivide this specific classification. Classification is complete at this level based on the material composition (less than 85% cotton), construction (multiple or cabled yarn), presentation (not for retail sale), and the precise fineness of the single yarn (exceeding 43 nm but not exceeding 52 nm). This ensures precise identification for customs purposes.
