5101.21.40.30 - Not finer than 58s

This HTS classification, 5101.21.40.30, specifically covers degreased shorn wool that has not undergone any further processing beyond the removal of grease. This means the wool is in its rawest state, having only been cleaned of natural oils and impurities. The critical defining characteristic for this category is that the wool's fineness is "not finer than 58s." This refers to the diameter of the wool fibers, measured in the English count system, where a higher number indicates finer fibers. Therefore, this classification is for wool fibers with a relatively coarser quality, not exceeding a 58s count.

This category is distinguished from its sibling, 5101.21.40.60, which covers wool that is "finer than 58s." The sole criterion for differentiation at this level is the fiber diameter. All other characteristics—being degreased, shorn wool, and unprocessed beyond degreasing—remain the same. This precise distinction is crucial for accurate duty assessment and trade statistics, as different fineness grades of wool are often subject to varying tariff rates.

As a leaf node, this classification does not have further subcategories. Classification under 5101.21.40.30 is the final determination for degreased shorn wool that meets the condition of not being finer than 58s and has not undergone any additional processing beyond the degreased state. Examples of products that might fall under this classification include bales of raw, degreased wool directly from sheep shearing that have been cleaned but not carded, combed, or otherwise treated to alter their inherent fiber characteristics beyond the removal of grease.
