4105.10.10.00 - Wet blues

This HTS classification, 4105.10.10.00, specifically covers "wet blues." These are sheep or lamb skins that have undergone a preliminary tanning process, typically using chromium salts, resulting in their characteristic blue color. The skins are still in a wet state and have had their wool removed. While they have been processed to a degree beyond raw hides, they have not yet been further prepared or finished into leather suitable for immediate use in manufacturing finished goods.

This category is distinguished from its sibling category, 4105.10.90.00 ("Other"), which would encompass wet-state sheep or lamb skins that do not meet the specific definition of "wet blues" or are processed using alternative tanning methods in the wet state. The "wet blues" classification is precisely for those skins treated with chromium salts, a distinct method that imparts specific properties and prepares them for subsequent tanning and finishing processes.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification is definitive for wet-blue sheep and lamb skins, without wool, whether or not split, but not further prepared. This means any sheep or lamb skins fitting this description and tanning method will fall under this specific code.
