5101.29.15.00 - Unimproved wool; other wool, not finer than 40s

This HTS category, 5101.29.15.00, specifically classifies unimproved wool and other wool that is not finer than 40s. The "unimproved" designation signifies wool that has undergone minimal processing beyond the degreasing stage. This means the wool has had its natural grease and impurities removed, but has not been carded or combed, nor has it been carbonized. The key defining characteristic for this subcategory is the fineness of the wool fibers, measured in "counts" or "s," where a lower number indicates a coarser fiber.

Distinguishing this category from its siblings is crucial for accurate classification. HTS code 5101.29.30.00 covers "Other wool, finer than 40s but not finer than 44s," and 5101.29.35.00 encompasses "Other wool, finer than 44s." Therefore, 5101.29.15.00 is reserved for wool that is coarser than 40s, meaning it has a lower count (e.g., 36s, 32s, 28s, etc.) or falls within the broader "unimproved wool" classification that is not specifically defined by a finer count. This level of detail ensures that wool of varying fiber diameters is correctly categorized for trade purposes.

As 5101.29.15.00 represents a leaf node in the HTS database, there are no further subcategories. Classification within this code is determined by the physical characteristic of fiber fineness (not finer than 40s) and the processing stage (degreased, not carded, combed, or carbonized). This often includes wool sourced directly from sheep that has undergone basic cleaning and degreasing, suitable for further processing into yarns and fabrics where coarser wools are desired.
