4102.10.10.00 - Not pretanned

This HTS category, 4102.10.10.00, specifically covers raw sheep or lamb skins that retain their wool. These skins can be in various states of preservation, including fresh, salted, dried, limed, or pickled, but importantly, they have not undergone tanning or any further preparation that would alter them into leather. The key defining characteristic is the presence of wool, which distinguishes them from other sheep and lamb skins.

The primary distinction from its sibling category, "Other" (referring to sheep and lamb skins without wool), lies solely in the retention of the wool covering. This category is for skins where the wool is still attached, regardless of whether it's been shorn, and excludes any skins that have been de-wooled as part of the preservation or preparation process.

As this is a leaf node in the HTS classification system, there are no further subcategories. The classification ends here, with the defining criteria being that the skins are from sheep or lambs, are not tanned, and still have their wool on. Examples include raw pelts intended for processing into wool products or as raw material for certain leather goods where the wool is a desired feature.
