4102.29.10 - Not pretanned

This HTS category encompasses raw sheep or lamb skins that have undergone preservation treatments such as salting, drying, liming, or pickling, but have not yet been tanned or further processed into parchment or similar materials. Crucially, these skins are characterized by the absence of wool. The "not pretanned" designation signifies that the skins are in an intermediate state, ready for subsequent tanning processes to produce leather.

The "Other" designation at this level distinguishes these skins from those specifically classified under other subheadings within Chapter 41. For instance, it differentiates from skins with wool on or those specifically excluded by note 1(c) to the chapter, ensuring a precise classification based on the removal of wool and the absence of further preparation beyond basic preservation.

Within this category, further subdivisions exist to refine classification. The subcategories "Hair sheep and cabretta skins" and "Other" allow for a more granular identification based on specific types of sheep or lamb skins. This distinction is important for trade statistics and potential duty rate variations, recognizing the unique characteristics and market values of different skin types.
