5101.11.60.60 - Finer than 58s

This HTS classification, 5101.11.60.60, specifically covers greasy wool obtained by shearing that is finer than 58s in terms of its fiber diameter. This designation relates to the quality and fineness of the wool fibers, measured in terms of "counts" or micron diameter, where a higher number generally indicates finer wool. The "greasy" condition signifies that the wool retains its natural lanolin content, which is a protective coating that needs to be removed through scouring processes during manufacturing.

This category is distinguished from its sibling, 5101.11.60.30, by the specific fineness criterion. While both are greasy, shorn wool, the primary differentiating factor here is the fiber diameter; 5101.11.60.60 pertains to wool classified as finer than 58s, implying a higher quality and typically softer texture compared to wool classified as not finer than 58s. This distinction is crucial for tariff purposes as it can reflect differences in end-use applications and market value.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification at this level relies solely on the accurate determination of the wool's condition (greasy), origin (shorn wool), and specifically its fiber fineness being finer than the 58s threshold. This level of detail is essential for accurate import and export declarations, ensuring compliance with trade regulations and correct duty assessment.
