5101.29.40 - Other

This HTS classification, specifically 5101.29.40, pertains to wool that has been degreased but not carbonized, and which falls under the broader "Other" category within this sub-heading. This designation is applied to wool that has undergone the degreasing process to remove natural grease, waxes, and dirt, but has not been subjected to further processing such as carbonizing to remove vegetable matter. The "Other" descriptor indicates it does not fit into more specific sub-classifications that might exist at a higher level of detail, typically related to the fineness or intended use of the wool.

It is important to distinguish this category from its sibling, "Unimproved wool; other wool, not finer than 46s." While both relate to degreased, non-carbonized wool, the sibling specifically addresses wool that is either unimproved (meaning minimal processing beyond the basic removal of grease) or has a fiber fineness not exceeding 46s. This current category, 5101.29.40, therefore covers degreased, non-carbonized wool that does not meet the specific criteria of the sibling, suggesting it may have a different fineness or have undergone slightly more preparation beyond basic degreasing without reaching the carbonized stage.

The subcategories within 5101.29.40 further refine the classification based on the fiber fineness of the wool. The subdivision into "Not finer than 58s" (5101.29.40.30) and "Finer than 58s" (5101.29.40.60) allows for a more precise categorization of the wool's quality and potential applications. This distinction is crucial for customs purposes as the fineness of wool significantly impacts its market value and suitability for different textile manufacturing processes.
