5101.29.40.60 - Finer than 58s 🖩

This HTS category, 5101.29.40.60, specifically covers degreased wool that has not been carbonized and is classified as finer than 58s. This implies that the wool has undergone a process to remove natural grease and impurities, but has not been treated to remove cellulosic materials. The fineness of the wool is a critical determinant for classification within this heading, indicating a higher quality and finer fiber diameter suitable for more delicate textile applications.

The distinguishing feature of this category from its sibling, 5101.29.40.30 ("Not finer than 58s"), lies solely in the measured fineness of the wool fibers. While both are degreased, not carbonized, and otherwise unprocessed beyond degreasing, this classification is reserved for wool exhibiting a fiber diameter that meets the criteria for being "finer than 58s." This distinction is paramount for duty rate determination and statistical reporting, as finer wools often carry different trade implications.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification into 5101.29.40.60 is final based on the criteria of being degreased, not carbonized, not processed beyond degreasing, and having a fiber fineness finer than 58s. Examples of goods falling here include raw wool that has been washed to remove grease but otherwise remains in its natural state, intended for spinning into fine yarns for apparel and other high-end textile products.
