5101.30.30.00 - Other wool, finer than 44s but not finer than 46s 🖩

This HTS category, 5101.30.30.00, specifically classifies carbonized wool that has undergone no further processing beyond the carbonization stage. This means the wool has been treated to remove vegetable matter but has not been carded, combed, or subjected to any other preparatory steps for spinning. The key defining characteristic here is its fineness, specifically wool that is finer than 44s but not exceeding 46s in terms of wool count.

This classification distinguishes itself from its siblings primarily by its precise fineness range and the degree of processing. Category 5101.30.10.00 covers unimproved wool or other wool not finer than 40s, while 5101.30.15.00 addresses wool finer than 40s but not finer than 44s. Therefore, 5101.30.30.00 captures the intermediate fineness range between these two, while still being limited to carbonized wool only. The sibling category 5101.30.40.00 acts as a residual, encompassing other carbonized wools not otherwise specified.

As a leaf node, this classification does not have further subcategories. The classification criteria rely solely on the material (wool), its state of processing (carbonized, unprocessed beyond carbonization), and its fineness (finer than 44s but not finer than 46s). When classifying wool under this heading, customs professionals will need to accurately determine the wool count and confirm that no carding, combing, or other mechanical processing has occurred after carbonization.
