5101.11.20.00 - Unimproved wool; other wool, not finer than 40s 🖩

This HTS classification, 5101.11.20.00, specifically designates "Unimproved wool; other wool, not finer than 40s." This category encompasses raw, unshorn wool (often referred to as "unimproved wool" in this context) and other wool that has not undergone carding or combing. The defining characteristic for inclusion here is the wool's fineness, measured in English counts (often denoted as "s"). Wool classified under this code has a fineness of 40s or coarser, meaning it has a lower number of fibers per unit of length compared to finer wools. This typically results in a thicker, more robust fiber.

The primary distinction between this category and its siblings lies in the fineness of the wool. HTS code 5101.11.20.00 covers wool that is "not finer than 40s." In contrast, sibling category 5101.11.40.00 deals with wool that is finer than 40s but not finer than 44s, and 5101.11.50.00 covers wool that is finer than 44s. Therefore, the numerical "s" value is the critical differentiating factor. This classification is relevant for wool intended for applications where coarser fibers are suitable, such as upholstery, carpets, or heavier weight apparel.

As this HTS code is a leaf node, there are no further subcategories to introduce. Classification decisions at this level are final and do not branch out into more specific subdivisions. Any wool meeting the criteria of being unimproved or other wool, not finer than 40s, and being in its greasy state (including fleece-washed wool), will fall directly under this code.
