5101.29.65.00 - Unimproved wool; other wool, not finer than 46s

This HTS category, 5101.29.65.00, specifically classifies unimproved wool that has been degreased but not carbonized, and is not finer than 46s count. "Unimproved" signifies that the wool has not undergone further processing beyond degreasing to remove natural oils and impurities. The "other wool" designation, combined with the specification "not finer than 46s," means this category encompasses wool fibers that fall within a broader range of coarser qualities, excluding the finer grades typically found in other subdivisions.

Distinguishing this category from its sibling, 5101.29.70.00, hinges on the specific type of wool covered. While 5101.29.70.00 might encompass other "other" degreased, non-carbonized wools not fitting into more specific sub-classifications, 5101.29.65.00 is precisely defined by its coarser grade (not finer than 46s) and its unimproved state. This level of detail is crucial for accurate tariff application, ensuring that wools of similar physical characteristics are consistently classified.

As this is a leaf node in the HTS database, there are no further subcategories to introduce. The classification ends at this specific description, indicating that any wool meeting all criteria – degreased, not carbonized, unimproved, and not finer than 46s – will be assigned to 5101.29.65.00. Examples within this category would include raw wool of various sheep breeds that, after grease removal, falls within the coarser counts, typically used in applications like carpet manufacturing or heavy textiles where extreme fineness is not a requirement.
