4102.29 - Other:

This HTS category, 4102.29, encompasses raw sheep or lamb skins that have been processed to remove their wool. These skins are preserved through methods such as salting, drying, liming, or pickling, but importantly, they have not undergone tanning or any further preparation that would render them leather. The "without wool on" qualifier specifically excludes skins where the wool remains attached, which would fall under a different classification.

Distinguishing this category from its sibling, 4102.21.00 (Pickled), it's important to note that while "pickled" is a preservation method, this broader category of "Other" includes all de-wooled sheep and lamb skins that have been preserved but do not fit into the specifically defined "pickled" subcategory. This could include skins preserved by other means or those that have undergone some limited preparation beyond basic preservation but are not yet tanned.

Within this "Other" category, further subdivisions exist to refine classification. The subcategory 4102.29.10 specifically addresses skins that have not been pretanned. This signifies a stage of processing prior to the development of recognizable leather. The existence of further "Other" subcategories, if applicable, would then account for any remaining de-wooled, preserved sheep and lamb skins that do not meet the criteria for being pretanned or other specifically defined stages of preparation.
