5101.19.50.00 - Other wool, finer than 44s

This HTS classification, 5101.19.50.00, pertains to greasy wool that is not carded or combed, and specifically excludes unimproved wool and wool finer than 46s. The core characteristic defining this category is its wool quality, measured by its fineness, which is a key determinant in wool processing and end-use applications. Greasy wool, as per the parent categories, means it still contains its natural oils, dirt, and impurities, and has not undergone any carding or combing processes.

This category is distinguished from its siblings by its specific fineness range. While 5101.19.20.00 covers unimproved wool and other wool not finer than 40s, and 5101.19.40.00 encompasses other wool finer than 40s but not finer than 44s, this category, 5101.19.50.00, captures greasy wool that is finer than 44s. This finer quality wool is typically associated with higher-value textile products.

As a leaf node, this classification does not have further subcategories. Therefore, the primary focus for classification into this category rests on confirming that the imported wool meets the criteria of being greasy, not carded or combed, and having a fineness exceeding 44s, while excluding the specific definitions covered by its siblings. Examples of wool that would fall here include raw merino wool or other fine crossbred wools in their natural, unprocessed state, with a staple length and fineness suitable for advanced textile manufacturing.
