5101.30.65.00 - Unimproved wool; other wool, not finer than 46s

This HTS category, 5101.30.65.00, specifically covers "other" unimproved wool that is not finer than 46s, after undergoing the carbonization process. Carbonization is a method used to remove vegetable matter and other impurities from wool by treating it with acid. The "other" designation here signifies wool that does not fall under any more specific carbonized wool classifications within this HTS subdivision. The "not finer than 46s" criterion refers to the wool's quality or fineness, indicating a coarser grade of wool, as measured by the count system.

Distinguishing this classification from its sibling, 5101.30.70.00 ("Other"), is crucial for accurate duty assessment. While both fall under "Other" carbonized wool, the preceding subheadings (which are not detailed here but would be present at higher levels of the hierarchy) would have defined more specific types of carbonized wool. This node, 5101.30.65.00, is for carbonized wool that is not finer than 46s and *doesn't fit* into those more narrowly defined categories, thereby encompassing a broader range of coarser carbonized wools.

As a leaf node in the HTS database, 5101.30.65.00 has no further subcategories. Therefore, classification into this code relies entirely on meeting the established criteria of being carbonized, unimproved wool that is not finer than 46s, and not being classifiable under any more specific provision. Examples might include carbonized wool from sheep breeds known for producing coarser fibers, intended for applications where extreme fineness is not a requirement, such as in felts, certain types of carpets, or industrial textiles. The key is the absence of finer wool characteristics and the presence of the carbonization treatment.
