5205.44.00.21 - Compact (301)

This HTS category encompasses multiple (folded) or cabled yarns of combed cotton fibers, specifically where each single yarn within the fold or cable has a linear density exceeding 52 but not exceeding 80 nanometers (nm). These yarns are not intended for retail sale and contain 85 percent or more by weight of cotton. The "Compact" designation signifies a specific yarn spinning technology that results in a stronger, more uniform yarn with reduced hairiness.

This classification is distinguished from its sibling category, 5205.44.00.29 "Other," by the explicit mention of "Compact" spinning. While both categories cover multiple (folded) or cabled yarns of combed cotton within the specified linear density range, this specific sub-heading isolates yarns produced using the compact spinning method, which imparts distinct characteristics and often a higher value.

As this is a leaf node, there are no further subcategories under this HTS code. Therefore, the focus for classification under 5205.44.00.21 rests on confirming the material composition (85% or more cotton), the construction (multiple or cabled yarn of combed fibers), the specific linear density range of the single yarn (exceeding 52 nm but not exceeding 80 nm), and the method of spinning (compact).
