5105.10.00.00 - Carded wool (400)

This classification covers wool that has undergone a carding process, preparing it for further manufacturing into textiles. Carding is a mechanical process that disentangles, cleans, and aligns wool fibers, creating a web or sliver that is then condensed into a roving. This specific category is for wool that has been carded but not yet combed, resulting in fibers that are parallel but may still contain some short fibers and impurities.

Distinguished from its siblings, this category is solely focused on carded wool, unlike the broader "Wool tops and other combed wool" which includes wool that has been combed to remove shorter fibers and further align the longer ones. It also differs from "Fine animal hair, carded or combed" and "Coarse animal hair, carded or combed" by specifically referring to wool, which is defined by its crimp and fineness, rather than other types of animal hair.

As a leaf node, 5105.10.00.00 does not have further subdivisions. Therefore, classification within this code relies on accurately identifying the material as wool and confirming that it has undergone carding as its primary mechanical preparation. Examples include wool roving produced directly from the carding machine, intended for spinning into yarn or other textile applications.
