5101.29.30.00 - Other wool, finer than 40s but not finer than 44s

This HTS category, 5101.29.30.00, specifically classifies "Other wool, finer than 40s but not finer than 44s." This refers to degreased wool that has not been carded or combed and has undergone no further processing beyond the degreased state. The key defining characteristic here is the wool's fineness, measured in "counts" which denote the number of hanks of yarn, each 560 yards long, that can be spun from one pound of wool.

This category distinguishes itself from its sibling, 5101.29.15.00, by being finer than 40s. It also differs from the sibling 5101.29.35.00 by being no finer than 44s, thus capturing a specific range of wool fineness within the broader classification of "other" degreased, uncarbonized wool. The designation "other wool" implies it is not the unimproved wool also classified within this section.

As this is a leaf node, there are no further subcategories. Classification within 5101.29.30.00 is therefore determined solely by the wool's fineness being within the specified range (greater than 40s and less than or equal to 44s) and meeting all other preceding criteria such as being degreased and unprocessed beyond that state.
